The "join" and "squeezelite" commands can alos be types at the prompt to start manually. Use "help" to see the list.
The squeezelite options are very similar to the regular squeezelite options. Differences are :
- the output is -o [BT <sinkname>] | [I2S]
- if you've compiled RESAMPLE option, normal soxr options are available using -R [-u <options>]. Note that anything above LQ or MQ will overload the CPU

The "join" and "squeezelite" commands can also be typed at the prompt to start manually. Use "help" to see the list.
The squeezelite options are very similar to the regular Linux ones. Differences are :
- the output is -o [\"BT -n <sinkname>\"] | [I2S]
- if you've compiled with RESAMPLE option, normal soxr options are available using -R [-u <options>]. Note that anything above LQ or MQ will overload the CPU
- if you've used RESAMPLE16, <options> are (b|l|m)[:i], with b = basic linear interpolation, l = 13 taps, m = 21 taps, i = interpolate filter coefficients
To add options that require quotes ("), escape them with \". For example, so use a BT speaker named MySpeaker and resample everything to 44100 (which is needed with Bluetooth) and use 16 bits resample with medium quality, the command line is:
# Additional misc notes
- for all libraries, add -mlongcalls
nvs_set autoexec2 str -v "squeezelite -o \"BT -n 'MySpeaker'\" -b 500:2000 -R -u m -Z 192000 -r \"44100-44100\""
# Additional misc notes to do you build
- for all libraries, add -mlongcalls.
- audio libraries are complicated to rebuild, open an issue if you really want to
- libmad, libflac (no esp's version), libvorbis (tremor - not esp's version), alac work
- libfaad does not really support real time, but if you want to try
