The instructions below assume that you have cloned the squeezelite-esp32 code that you want to build locally and that you have opened a command line/bash session in the folder that contains the code. Pull the most recent docker image for the environment: ``` -docker pull sle118/squeezelite-esp32-idfv43 +docker pull sle118/squeezelite-esp32-idfv435 ``` Then run the container interactively : ``` for windows: -docker run -v %cd%:/project -w /project -it sle118/squeezelite-esp32-idfv43 +docker run -v %cd%:/project -w /project -it sle118/squeezelite-esp32-idfv435 for linux: -docker run -it -v `pwd`:/workspace/squeezelite-esp32 sle118/squeezelite-esp32-idfv43 +docker run -it -v `pwd`:/workspace/squeezelite-esp32 sle118/squeezelite-esp32-idfv435 ``` The above command will mount this repo into the docker container and start a bash terminal.

The following is a summary of what is and is not supported: - -Supported: - - MPEG2, MPEG4 low complexity decoding (intensity stereo, M-S, TNS, PNS) - - spectral band replication (SBR), high-quality mode - - mono, stereo, and multichannel modes - - ADTS, ADIF, and raw data block file formats - -Not currently supported: - - main or SSR profile, LTP - - coupling channel elements (CCE) - - 960/1920-sample frame size - - low-power mode SBR - - downsampled (single-rate) SBR - - parametric stereo - -Highlights ----------- - - highly optimized for ARM processors (details in docs/ subdirectory) - - reference x86 implementation - - C and assembly code only (C++ not required for codec library) - - reentrant, statically linkable - - low memory (details in docs/ subdirectory) - - option to use Intel Integrated Performance Primitives (details below) - -Supported platforms and toolchains ----------------------------------- -This codec should run on any 32-bit fixed-point processor which can perform a full 32x32-bit -multiply (providing a 64-bit result). The following processors and toolchains are supported: - - x86, Microsoft Visual C++ - - x86, GNU toolchain (gcc) - - ARM, ARM Developer Suite (ADS) - - ARM, Microsoft Embedded Visual C++ - - ARM, GNU toolchain (gcc) - -ARM refers to any processor supporting ARM architecture v.4 or above. Thumb is not required. - -Generally ADS produces the fastest code. EVC 3 does not support inline assembly code for -ARM targets, so calls to MULSHIFT32 (smull on ARM) are left as function calls. This incurs -a significant performance penalty. For the fastest code on targets which do not normally use -ADS consider compiling with ADS, using the -S option to output assembly code, and -feeding this assembly code to the assembler of your choice. This might require some -syntax changes in the .S file. - -Adding support for a new processor is fairly simple. Simply add a new block to the file -real/assembly.h which implements the required inline assembly functions for your processor. -Something like - -... -#elif defined NEW_PROCESSOR - -/* you implement MULSHIFT32() and so forth */ - -#else -#error Unsupported platform in assembly.h -#endif - -Optionally you can rewrite or add assembly language files optimized for your platform. Note -that many of the algorithms are designed for an ARM-type processor, so performance of the -unmodified C code might be noticeably worse on other architectures. - -Adding support for a new toolchain is straightforward. Use the sample projects or the -Helix makefiles as a template for which source files to include. - -Multichannel ------------- -For multichannel, just set AAC_MAX_NCHANS in pub/aacdec.h to the desired max number -of channels (default = 2) and recompile. This increases RAM usage since more memory -is required to save state for multiple channels. See docs/memory.xls for details. - -Directory structure -------------------- -fixpt/ platform-independent code and tables, public API -fixpt/docs memory and CPU usage figures, callgraphs -fixpt/hxwrap Helix wrapper code and makefiles -fixpt/ipp source code which uses IPP for decoding (see the "IPP" section below) -fixpt/pub public header files -fixpt/real source code for RealNetworks' AAC decoder -fixpt/testwrap sample code to build a command-line test application - -Code organization ------------------ -fixpt/ - aacdec.c main decode functions, exports C-only API - aactabs.c common tables used by all implementations -fixpt/pub/ - aaccommon.h low-level codec API which aacdec.c calls - aacdec.h high-level codec API which applications call - statname.h symbols which get name-mangled by C preprocessor to allow static linking -fixpt/ipp source code for wrapper files which link in IPP libraries -fixpt/real full source code for RealNetworks AAC decoder, including SBR -fixpt/real/asm optimized assembly code files for certain platforms - -To build an AAC decoder library, you'll need to compile the top-level files and EITHER -real/*.c OR ipp/*.c and the appropriate IPP library. - -Decoder using Real code: aacdec.c + aactabs.c + real/*.c + real/asm/[platform]/*.s (if necessary) -Decoder using IPP code: aacdec.c + aactabs.c + ipp/*.c + ippac*.lib - -IPP ---- -For certain platforms Intel® has created highly-optimized object code libraries of DSP -routines. These are called the Intel® Integrated Performance Primitives (IPP). If IPP -libraries are available for a platform, this AAC decoder can link them in and use them -instead of the RealNetworks source code. To use IPP, you still need to build the top-level -files (aacdec.c, aactabs.c). You also build the files in ipp/*.c. These are just thin -wrappers which provide the glue logic between the top-level decode functions in -aacdec.c and the optimized DSP primitives in the IPP libraries. IPP libraries are not -included in this module. You must obtain them WITH A LICENSE directly from Intel. -Further info on the latest versions of IPP (as of the date of this readme) is available -from the URL below: - -http://www.intel.com/software/products/ipp/ - -This site explains how to obtain IPP and the terms under which IPP libraries may be used. -The code in this module is merely wrapper code which calls IPP functions.

Subject to the terms and -conditions of this License, Licensor hereby grants You, effective on the date -You accept this License (via downloading or using Covered Code or otherwise -indicating your acceptance of this License), a worldwide, royalty-free, -non-exclusive copyright license, to the extent of Licensor's copyrights cover -the Original Code, to do the following: - -2.1 You may reproduce, display, perform, modify and Deploy Covered Code, -provided that in each instance: - -(a) You must retain and reproduce in all copies of Original Code the copyright -and other proprietary notices and disclaimers of Licensor as they appear in the -Original Code, and keep intact all notices in the Original Code that refer to -this License; - -(b) You must include a copy of this License with every copy of Source Code of -Covered Code and documentation You distribute, and You may not offer or impose -any terms on such Source Code that alter or restrict this License or the -recipients' rights hereunder, except as permitted under Section 6; - -(c) You must duplicate, to the extent it does not already exist, the notice in -Exhibit A in each file of the Source Code of all Your Modifications, and cause -the modified files to carry prominent notices stating that You changed the files -and the date of any change; - -(d) You must make Source Code of all Your Externally Deployed Modifications -publicly available under the terms of this License, including the license grants -set forth in Section 3 below, for as long as you Deploy the Covered Code or -twelve (12) months from the date of initial Deployment, whichever is longer. You -should preferably distribute the Source Code of Your Deployed Modifications -electronically (e.g. download from a web site); and - -(e) if You Deploy Covered Code in object code, executable form only, You must -include a prominent notice, in the code itself as well as in related -documentation, stating that Source Code of the Covered Code is available under -the terms of this License with information on how and where to obtain such -Source Code. You must also include the Object Code Notice set forth in Exhibit A -in the "about" box or other appropriate place where other copyright notices are -placed, including any packaging materials. - -2.2 You expressly acknowledge and agree that although Licensor and each -Contributor grants the licenses to their respective portions of the Covered Code -set forth herein, no assurances are provided by Licensor or any Contributor that -the Covered Code does not infringe the patent or other intellectual property -rights of any other entity. Licensor and each Contributor disclaim any liability -to You for claims brought by any other entity based on infringement of -intellectual property rights or otherwise. As a condition to exercising the -rights and licenses granted hereunder, You hereby assume sole responsibility to -secure any other intellectual property rights needed, if any. For example, if a -third party patent license is required to allow You to make, use, sell, import -or offer for sale the Covered Code, it is Your responsibility to acquire such -license(s). - -2.3 Subject to the terms and conditions of this License, Licensor hereby grants -You, effective on the date You accept this License (via downloading or using -Covered Code or otherwise indicating your acceptance of this License), a -worldwide, royalty-free, perpetual, non-exclusive patent license under -Licensor's Applicable Patent Rights to make, use, sell, offer for sale and -import the Covered Code, provided that in each instance you comply with the -terms of this License. - -3. Your Grants. In consideration of, and as a condition to, the licenses granted -to You under this License: - -(a) You grant to Licensor and all third parties a non-exclusive, perpetual, -irrevocable, royalty free license under Your Applicable Patent Rights and other -intellectual property rights owned or controlled by You, to make, sell, offer -for sale, use, import, reproduce, display, perform, modify, distribute and -Deploy Your Modifications of the same scope and extent as Licensor's licenses -under Sections 2.1 and 2.2; and - -(b) You grant to Licensor and its subsidiaries a non-exclusive, worldwide, -royalty-free, perpetual and irrevocable license, under Your Applicable Patent -Rights and other intellectual property rights owned or controlled by You, to -make, use, sell, offer for sale, import, reproduce, display, perform, -distribute, modify or have modified (for Licensor and/or its subsidiaries), -sublicense and distribute Your Modifications, in any form and for any purpose, -through multiple tiers of distribution. - -(c) You agree not use any information derived from Your use and review of the -Covered Code, including but not limited to any algorithms or inventions that may -be contained in the Covered Code, for the purpose of asserting any of Your -patent rights, or assisting a third party to assert any of its patent rights, -against Licensor or any Contributor. - -4. Derivative Works. You may create a Derivative Work by combining Covered Code -with other code not otherwise governed by the terms of this License and -distribute the Derivative Work as an integrated product. In each such instance, -You must make sure the requirements of this License are fulfilled for the -Covered Code or any portion thereof, including all Modifications. - -4.1 You must cause any Derivative Work that you distribute, publish or -Externally Deploy, that in whole or in part contains or is derived from the -Covered Code or any part thereof, to be licensed as a whole at no charge to all -third parties under the terms of this License and no other license except as -provided in Section 4.2. You also must make Source Code available for the -Derivative Work under the same terms as Modifications, described in Sections 2 -and 3, above. - -4.2 Compatible Source Licenses. Software modules that have been independently -developed without any use of Covered Code and which contain no portion of the -Covered Code, Modifications or other Derivative Works, but are used or combined -in any way wtih the Covered Code or any Derivative Work to form a larger -Derivative Work, are exempt from the conditions described in Section 4.1 but -only to the extent that: the software module, including any software that is -linked to, integrated with, or part of the same applications as, the software -module by any method must be wholly subject to one of the Compatible Source -Licenses. Notwithstanding the foregoing, all Covered Code must be subject to the -terms of this License. Thus, the entire Derivative Work must be licensed under a -combination of the RPSL (for Covered Code) and a Compatible Source License for -any independently developed software modules within the Derivative Work. The -foregoing requirement applies even if the Compatible Source License would -ordinarily allow the software module to link with, or form larger works with, -other software that is not subject to the Compatible Source License. For -example, although the Mozilla Public License v1.1 allows Mozilla code to be -combined with proprietary software that is not subject to the MPL, if -MPL-licensed code is used with Covered Code the MPL-licensed code could not be -combined or linked with any code not governed by the MPL. The general intent of -this section 4.2 is to enable use of Covered Code with applications that are -wholly subject to an acceptable open source license. You are responsible for -determining whether your use of software with Covered Code is allowed under Your -license to such software. - -4.3 Mere aggregation of another work not based on the Covered Code with the -Covered Code (or with a work based on the Covered Code) on a volume of a storage -or distribution medium does not bring the other work under the scope of this -License. If You deliver the Covered Code for combination and/or integration with -an application previously provided by You (for example, via automatic updating -technology), such combination and/or integration constitutes a Derivative Work -subject to the terms of this License. - -5. Exclusions From License Grant. Nothing in this License shall be deemed to -grant any rights to trademarks, copyrights, patents, trade secrets or any other -intellectual property of Licensor or any Contributor except as expressly stated -herein. No right is granted to the trademarks of Licensor or any Contributor -even if such marks are included in the Covered Code. Nothing in this License -shall be interpreted to prohibit Licensor from licensing under different terms -from this License any code that Licensor otherwise would have a right to -license. Modifications, Derivative Works and/or any use or combination of -Covered Code with other technology provided by Licensor or third parties may -require additional patent licenses from Licensor which Licensor may grant in its -sole discretion. No patent license is granted separate from the Original Code or -combinations of the Original Code with other software or hardware. - -5.1. Trademarks. This License does not grant any rights to use the trademarks or -trade names owned by Licensor ("Licensor Marks" defined in Exhibit C) or to any -trademark or trade name belonging to any Contributor. No Licensor Marks may be -used to endorse or promote products derived from the Original Code other than as -permitted by the Licensor Trademark Policy defined in Exhibit C. - -6. Additional Terms. You may choose to offer, and to charge a fee for, warranty, -support, indemnity or liability obligations and/or other rights consistent with -the scope of the license granted herein ("Additional Terms") to one or more -recipients of Covered Code. However, You may do so only on Your own behalf and -as Your sole responsibility, and not on behalf of Licensor or any Contributor. -You must obtain the recipient's agreement that any such Additional Terms are -offered by You alone, and You hereby agree to indemnify, defend and hold -Licensor and every Contributor harmless for any liability incurred by or claims -asserted against Licensor or such Contributor by reason of any such Additional -Terms. - -7. Versions of the License. Licensor may publish revised and/or new versions of -this License from time to time. Each version will be given a distinguishing -version number. Once Original Code has been published under a particular version -of this License, You may continue to use it under the terms of that version. You -may also choose to use such Original Code under the terms of any subsequent -version of this License published by Licensor. No one other than Licensor has -the right to modify the terms applicable to Covered Code created under this -License. - -8. NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in part -pre-release, untested, or not fully tested works. The Covered Code may contain -errors that could cause failures or loss of data, and may be incomplete or -contain inaccuracies. You expressly acknowledge and agree that use of the -Covered Code, or any portion thereof, is at Your sole and entire risk. THE -COVERED CODE IS PROVIDED "AS IS" AND WITHOUT WARRANTY, UPGRADES OR SUPPORT OF -ANY KIND AND LICENSOR AND LICENSOR'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS -"LICENSOR" FOR THE PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY -DISCLAIM ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT -NOT LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY, OF -SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR PURPOSE, OF ACCURACY, OF QUIET -ENJOYMENT, AND NONINFRINGEMENT OF THIRD PARTY RIGHTS. LICENSOR AND EACH -CONTRIBUTOR DOES NOT WARRANT AGAINST INTERFERENCE WITH YOUR ENJOYMENT OF THE -COVERED CODE, THAT THE FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR -REQUIREMENTS, THAT THE OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR -ERROR-FREE, OR THAT DEFECTS IN THE COVERED CODE WILL BE CORRECTED. NO ORAL OR -WRITTEN DOCUMENTATION, INFORMATION OR ADVICE GIVEN BY LICENSOR, A LICENSOR -AUTHORIZED REPRESENTATIVE OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY. You -acknowledge that the Covered Code is not intended for use in high risk -activities, including, but not limited to, the design, construction, operation -or maintenance of nuclear facilities, aircraft navigation, aircraft -communication systems, or air traffic control machines in which case the failure -of the Covered Code could lead to death, personal injury, or severe physical or -environmental damage. Licensor disclaims any express or implied warranty of -fitness for such uses. - -9. LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO EVENT -SHALL LICENSOR OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, SPECIAL, -INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE OR -YOUR USE OR INABILITY TO USE THE COVERED CODE, OR ANY PORTION THEREOF, WHETHER -UNDER A THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE OR STRICT -LIABILITY), PRODUCTS LIABILITY OR OTHERWISE, EVEN IF LICENSOR OR SUCH -CONTRIBUTOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND -NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY REMEDY. SOME -JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY OF INCIDENTAL OR -CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY TO YOU. In no event -shall Licensor's total liability to You for all damages (other than as may be -required by applicable law) under this License exceed the amount of ten dollars -($10.00). - -10. Ownership. Subject to the licenses granted under this License, each -Contributor retains all rights, title and interest in and to any Modifications -made by such Contributor. Licensor retains all rights, title and interest in and -to the Original Code and any Modifications made by or on behalf of Licensor -("Licensor Modifications"), and such Licensor Modifications will not be -automatically subject to this License. Licensor may, at its sole discretion, -choose to license such Licensor Modifications under this License, or on -different terms from those contained in this License or may choose not to -license them at all. - -11. Termination. - -11.1 Term and Termination. The term of this License is perpetual unless -terminated as provided below.

Upon termination, You agree to immediately stop any -further use, reproduction, modification, sublicensing and distribution of the -Covered Code and to destroy all copies of the Covered Code that are in your -possession or control. All sublicenses to the Covered Code which have been -properly granted prior to termination shall survive any termination of this -License. Provisions which, by their nature, should remain in effect beyond the -termination of this License shall survive, including but not limited to Sections -3, 5, 8, 9, 10, 11, 12.2 and 13. No party will be liable to any other for -compensation, indemnity or damages of any sort solely as a result of terminating -this License in accordance with its terms, and termination of this License will -be without prejudice to any other right or remedy of any party. - -12. Miscellaneous. - -12.1 Government End Users. The Covered Code is a "commercial item" as defined in -FAR 2.101.

(a) If for any reason a court of competent jurisdiction finds -any provision of this License, or portion thereof, to be unenforceable, that -provision of the License will be enforced to the maximum extent permissible so -as to effect the economic benefits and intent of the parties, and the remainder -of this License will continue in full force and effect.

The following is a summary of what is and is not supported: - -Supported: - - MPEG2, MPEG4 low complexity decoding (intensity stereo, M-S, TNS, PNS) - - spectral band replication (SBR), high-quality mode - - mono, stereo, and multichannel modes - - ADTS, ADIF, and raw data block file formats - -Not currently supported: - - main or SSR profile, LTP - - coupling channel elements (CCE) - - 960/1920-sample frame size - - low-power mode SBR - - downsampled (single-rate) SBR - - parametric stereo - -Highlights ----------- - - highly optimized for ARM processors (details in docs/ subdirectory) - - reference x86 implementation - - C and assembly code only (C++ not required for codec library) - - reentrant, statically linkable - - low memory (details in docs/ subdirectory) - - option to use Intel Integrated Performance Primitives (details below) - -Supported platforms and toolchains ----------------------------------- -This codec should run on any 32-bit fixed-point processor which can perform a full 32x32-bit -multiply (providing a 64-bit result). The following processors and toolchains are supported: - - x86, Microsoft Visual C++ - - x86, GNU toolchain (gcc) - - ARM, ARM Developer Suite (ADS) - - ARM, Microsoft Embedded Visual C++ - - ARM, GNU toolchain (gcc) - -ARM refers to any processor supporting ARM architecture v.4 or above. Thumb is not required. - -Generally ADS produces the fastest code. EVC 3 does not support inline assembly code for -ARM targets, so calls to MULSHIFT32 (smull on ARM) are left as function calls. This incurs -a significant performance penalty. For the fastest code on targets which do not normally use -ADS consider compiling with ADS, using the -S option to output assembly code, and -feeding this assembly code to the assembler of your choice. This might require some -syntax changes in the .S file. - -Adding support for a new processor is fairly simple. Simply add a new block to the file -real/assembly.h which implements the required inline assembly functions for your processor. -Something like - -... -#elif defined NEW_PROCESSOR - -/* you implement MULSHIFT32() and so forth */ - -#else -#error Unsupported platform in assembly.h -#endif - -Optionally you can rewrite or add assembly language files optimized for your platform. Note -that many of the algorithms are designed for an ARM-type processor, so performance of the -unmodified C code might be noticeably worse on other architectures. - -Adding support for a new toolchain is straightforward. Use the sample projects or the -Helix makefiles as a template for which source files to include. - -Multichannel ------------- -For multichannel, just set AAC_MAX_NCHANS in pub/aacdec.h to the desired max number -of channels (default = 2) and recompile. This increases RAM usage since more memory -is required to save state for multiple channels. See docs/memory.xls for details. - -Directory structure -------------------- -fixpt/ platform-independent code and tables, public API -fixpt/docs memory and CPU usage figures, callgraphs -fixpt/hxwrap Helix wrapper code and makefiles -fixpt/ipp source code which uses IPP for decoding (see the "IPP" section below) -fixpt/pub public header files -fixpt/real source code for RealNetworks' AAC decoder -fixpt/testwrap sample code to build a command-line test application - -Code organization ------------------ -fixpt/ - aacdec.c main decode functions, exports C-only API - aactabs.c common tables used by all implementations -fixpt/pub/ - aaccommon.h low-level codec API which aacdec.c calls - aacdec.h high-level codec API which applications call - statname.h symbols which get name-mangled by C preprocessor to allow static linking -fixpt/ipp source code for wrapper files which link in IPP libraries -fixpt/real full source code for RealNetworks AAC decoder, including SBR -fixpt/real/asm optimized assembly code files for certain platforms - -To build an AAC decoder library, you'll need to compile the top-level files and EITHER -real/*.c OR ipp/*.c and the appropriate IPP library. - -Decoder using Real code: aacdec.c + aactabs.c + real/*.c + real/asm/[platform]/*.s (if necessary) -Decoder using IPP code: aacdec.c + aactabs.c + ipp/*.c + ippac*.lib - -IPP ---- -For certain platforms Intel® has created highly-optimized object code libraries of DSP -routines. These are called the Intel® Integrated Performance Primitives (IPP). If IPP -libraries are available for a platform, this AAC decoder can link them in and use them -instead of the RealNetworks source code. To use IPP, you still need to build the top-level -files (aacdec.c, aactabs.c). You also build the files in ipp/*.c. These are just thin -wrappers which provide the glue logic between the top-level decode functions in -aacdec.c and the optimized DSP primitives in the IPP libraries. IPP libraries are not -included in this module. You must obtain them WITH A LICENSE directly from Intel. -Further info on the latest versions of IPP (as of the date of this readme) is available -from the URL below: - -http://www.intel.com/software/products/ipp/ - -This site explains how to obtain IPP and the terms under which IPP libraries may be used. -The code in this module is merely wrapper code which calls IPP functions.

Then within that group, a look-up table is + used to determine which codeword the symbol is. + The table is created by ordering the codeword in the table according to their + normalized shifted binary value, i.e., all the codewords are left + shifted to meet the maximum codelength. Example, max codelength is + 10, the codeword with lenth 3 will left shift by 7. + The binary values of after the shift are sorted. + Then the sorted table is divided into several partition. + At the VLC decoding period, input is read in at max codelenght. + The partition is decided using if-else logic. + Inside each partition, a look-up table is used to map the input value + to a correct symbol. Table entries can appear to be repeated according + to the humming distance between adjacent codewords. + +------------------------------------------------------------------------------ + REQUIREMENTS + + +------------------------------------------------------------------------------ + REFERENCES + + (1) MPEG-2 NBC Audio Decoder + "This software module was originally developed by AT&T, Dolby + Laboratories, Fraunhofer Gesellschaft IIS in the course of development + of the MPEG-2 NBC/MPEG-4 Audio standard ISO/IEC 13818-7, 14496-1,2 and + 3.

This means, that a single + block of IMDCT data does not correspond to the original block on which the + IMDCT was performed. When subsequent blocks of inverse transformed data + are added (still using 50% overlap), the errors introduced by the + transform cancels out.Thanks to the overlapping feature, the IMDCT is very + useful for quantization. It effectively removes the otherwise easily + detectable blocking artifact between transform blocks. + + N = twice the length of input vector X + y = vector of length N, will hold fixed point IDCT + p = 0:1:N-1 + + 2 N/2-1 + y(p) = --- SUM X(m)*cos(pi/(2*N)*(2*p+1+N/2)*(2*m+1)) + N m=0 + + The window that completes the TDAC is applied before calling this function. + The IMDCT can be calculated using an IFFT, for this, the IMDCT need be + rewritten as an odd-time odd-frequency discrete Fourier transform. Thus, + the IMDCT can be calculated using only one n/4 point FFT and some pre and + post-rotation of the sample points. + + + where X(k) is the input with N frequency lines + + X(k) ---------------------------- + | + | + Pre-rotation by exp(j(2pi/N)(k+1/8)) + | + | + N/4- point IFFT + | + | + Post-rotation by exp(j(2pi/N)(n+1/8)) + | + | + ------------- x(n) In the time domain + + +------------------------------------------------------------------------------ + REQUIREMENTS + + This function should provide a fixed point IMDCT with an average + quantization error less than 1 % (variance and mean). + +------------------------------------------------------------------------------ + REFERENCES + + [1] Analysis/Synthesis Filter Bank design based on time domain + aliasing cancellation + Jhon Princen, et. al. + IEEE Transactions on ASSP, vol ASSP-34, No. 5 October 1986 + Pg 1153 - 1161 + + [2] Regular FFT-related transform kernels for DCT/DST based + polyphase filterbanks + Rolf Gluth + Proc.

This means, that a single + block of MDCT data does not correspond to the original block on which the + MDCT was performed. When subsequent blocks of data are added (still using + 50% overlap), the errors introduced by the transform cancels out. + Thanks to the overlapping feature, the MDCT is very useful for + quantization.

This module consists of +an inverse modified discrete cosine transform (IMDCT), and a window and an +overlap-add function. In order to adapt the time/frequency resolution of the +filterbank to the characteristics of the input signal, a block switching tool +is also adopted. N represents the window length, where N is a function of the +window_sequence. For each channel, the N/2 time-frequency values are +transformed into the N time domain values via the IMDCT. After applying the +window function, for each channel, the first half of the sequence is added to +the second half of the previous block windowed sequence to reconstruct the +output samples for each channel outi,n. + +The adaptation of the time-frequency resolution of the filterbank to the +characteristics of the input signal is done by shifting between transforms +whose input lengths are either 2048 or 256 samples. By enabling the block +switching tool, the following transitions are meaningful: + +from ONLY_LONG_SEQUENCE to { LONG_START_SEQUENCE + ONLY_LONG_SEQUENCE + +from LONG_START_SEQUENCE to { LONG_STOP_SEQUENCE + EIGHT_SHORT_SEQUENCE + +from LONG_STOP_SEQUENCE to { LONG_START_SEQUENCE + ONLY_LONG_SEQUENCE + +from EIGHT_SHORT_SEQUENCE to { LONG_STOP_SEQUENCE + EIGHT_SHORT_SEQUENCE + +Window shape decisions are made by the encoder on a frame-by-frame-basis. +The window selected is applicable to the second half of the window function +only, since the first half is constrained to use the appropriate window +shape from the preceding frame. +The 2048 time-domain values x'(i)(n), (i window, n sample) to be windowed are +the last 1024 values of the previous window_sequence concatenated with 1024 +values of the current block. The formula below shows this fact: + + | x(i-1)(n+1024) for 0 < n < 1024 + x'(i)(n) { + | x(i)(n) for 1024 < n < 2048 + + +Buffer Time_data data from previous Frequency to Time conversion, used +for overlap and add + +Once the window shape is selected, the window_shape syntax element is +initialized. Together with the chosen window_sequence all information needed +for windowing exist. +With the window halves described below all window_sequences can be assembled. +For window_shape == 1, the window coefficients are given by the Kaiser - +Bessel derived (KBD) window. +Otherwise, for window_shape == 0, a sine window is employed. + +The window length N can be 2048 or 256 for the KBD and the sine window. +All four window_sequences explained below have a total length of 2048 +samples. +For all kinds of window_sequences the window_shape of the left half of +the first transform window is determined by the window shape of the previous +block. + +In the case of EIGHT_SHORT_SEQUENCE the processing is done in-place and +in descendent order to avoid using extra memory. +The ordering is as follows: + + Pn: Previous data for window n + Cn: Current data for window n + + + 128 freq. + samples + FREQ ++++++ +IN =========================== + \ + \ + -> 256 time + samples + + P8 C8 + 8 #######++++++ + P7 C7 + 7 #######++++++ + : : + : : + P2 C2 + 2 #######++++++ + P1 C1 + 1 #######++++++ + TIME +OUT ============================================================== + +------------------------------------------------------------------------------ + REQUIREMENTS + + This module shall implement a scheme to switch between window types + +------------------------------------------------------------------------------ + REFERENCES + + [1] ISO 14496-3:1999, pag 111 + +------------------------------------------------------------------------------ + PSEUDO-CODE + + + + IF ( wnd_seq == EIGHT_SHORT_SEQUENCE) + THEN + + FOR ( i=0; i=0; wnd--) + + pFreqInfo = &Frequency_data[ wnd*SHORT_WINDOW]; + + CALL IMDCT( pFreqInfo, SHORT_BLOCK1); + MODIFYING(pFreqInfo) + + + IF (wnd == 0) + THEN + pShort_Window_1 = &Short_Window[wnd_shape_prev_bk][0]; + ELSE + pShort_Window_1 = &Short_Window[wnd_shape_this_bk][0]; + ENDIF + + pShort_Window_2 = + &Short_Window[wnd_shape->this_bk][SHORT_WINDOW_m_1]; + + FOR( i=0, j=SHORT_WINDOW; i>16; + + +#else + +#define limiter( y, x) z = ((x + ROUNDING )>>SCALING); \ + if ((z>>15) != (z>>31)) \ + { \ + z = (z >> 31) ^ INT16_MAX; \ + } \ + y = (Int16)(z); + +#endif + + +/*---------------------------------------------------------------------------- +; DEFINES +; Include all pre-processor statements here.

This module consists of +a modified discrete cosine transform (MDCT), (windowing and DCT). +In order to adapt the time/frequency resolution of the filterbank to the + characteristics of the input signal, a block switching tool is also +adopted. N represents the window length, where N is a function of the +window_sequence. For each channel, the N time values are transformed into the +N/2 frequency domain values via the MDCT. + +The adaptation of the time-frequency resolution of the filterbank to the +characteristics of the input signal is done by shifting between transforms +whose input lengths are either 2048 or 256 samples. By enabling the block +switching tool, the following transitions are meaningful: + +from ONLY_LONG_SEQUENCE to { LONG_START_SEQUENCE + ONLY_LONG_SEQUENCE + +from LONG_START_SEQUENCE to { LONG_STOP_SEQUENCE + EIGHT_SHORT_SEQUENCE + +from LONG_STOP_SEQUENCE to { LONG_START_SEQUENCE + ONLY_LONG_SEQUENCE + +from EIGHT_SHORT_SEQUENCE to { LONG_STOP_SEQUENCE + EIGHT_SHORT_SEQUENCE + +Window shape decisions are made by the encoder on a frame-by-frame-basis. +The window selected is applicable to the second half of the window function +only, since the first half is constrained to use the appropriate window +shape from the preceding frame. +The 2048 time-domain values x'(i)(n), (i window, n sample) to be windowed are +the last 1024 values of the previous window_sequence concatenated with 1024 +values of the current block. The formula below shows this fact: + + | x(i-1)(n+1024) for 0 < n < 1024 + x'(i)(n) { + | x(i)(n) for 1024 < n < 2048 + + + +Once the window shape is selected, the window_shape syntax element is +initialized. Together with the chosen window_sequence all information needed +for windowing exist. +With the window halves described below all window_sequences can be assembled. +For window_shape == 1, the window coefficients are given by the Kaiser - +Bessel derived (KBD) window. +Otherwise, for window_shape == 0, a sine window is employed. + +The window length N can be 2048 or 256 for the KBD and the sine window. +All four window_sequences explained below have a total length of 2048 +samples. +For all kinds of window_sequences the window_shape of the left half of +the first transform window is determined by the window shape of the previous +block. +------------------------------------------------------------------------------ + REQUIREMENTS + + This module shall implement a scheme to switch between window types and + in turn perform time to frequency transformations + + +------------------------------------------------------------------------------ + REFERENCES + + [1] ISO 14496-3:1999, pag 111 + +------------------------------------------------------------------------------ + PSEUDO-CODE + + IF ( wnd_seq == EIGHT_SHORT_SEQUENCE) + THEN + + + FOR ( wnd=0;
