Streaming OPUS example

Postby Mutski » Thu May 09, 2024 5:30 am

Hi all

Looking for any examples of streaming audio using OPUS codec. The codec examples in the ADF are for reading from a SD card and using the AAC codec and there's little documentation around it anyway. I'm trying to read from a TLV320 audio codec chip (got this working ok), compress the audio using OPUS codec, and send via UDP. Then receive it on another ESP32 and spit it back out again - basically a 2 way walkie talkie device.

At the moment I've got it working great using uncompressed data straight out of the TLV320 but I'd like to get the bandwidth down a bit. Anybody got any examples? Google isn't helping me today.

Cheers

Matt

It also seems that the ADF only has encoding functions and nothing to decode the Opus?
