The squeezelite options are very similar to the regular squeezelite options. Differences are :
- the output is -o [BT <sinkname>] | [I2S] The "join" and "squeezelite" commands can also be typed at the prompt to start manually. Use "help" to see the list.
- 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 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 - 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 nvs_set autoexec2 str -v "squeezelite -o \"BT -n 'MySpeaker'\" -b 500:2000 -R -u m -Z 192000 -r \"44100-44100\""
- for all libraries, add -mlongcalls
