Resample to 32 bits

[expresspotato]

Hello,

We interface with a custom processor, who's I2S bit width is fixed at 32. In esp-adf, filter-resample only supports resampling to 16 bits. We need the resample filter to support 32 bits as a supported destination bit width.

Any plans?

@expresspotato One new rate conversion has beed released on https://components.espressif.com/components/espressif/esp_audio_effects/versions/1.0.1, it's support all bits.

So while this does produce 32 bit output, there appears to be a bug in esp-adf / esp-idf that results in distortion at 32 bits...
