Dynamic range compression question

Hello to all,

I am a complete beginner.
I use a LyraT v.4.3 and am looking for a way to include a dynamic range compressor in the pipeline. Classic with threshold, attack time etc.
Unfortunately I have not found an example function.
Is there a possibility to run the streamed contents in the passthru
for example over a Compressor?
Thanks in advance

DRC(Dynamic range compression) is not ready, would you like try ALC(https://github.com/espressif/esp-adf/tr ... peline_alc), this feature is similar, so evaluate if it meets your needs.

Hello and thank you for the answer,

is it possible to add the use_alc_set_volume to the passthru example?
I have tried so far to combine it and use the I2s_stream reader instead of the wav_decoder etc, but I don't get the same effect as when using the SD card.
