Is it possible to add Opus for better quality audio? #11

Closed happytm closed 9 months ago

I know it will reduce range with higher data rate Opus require but audio quality would be improved.

I am asking as you implemented Opus codec in your android app version. Can it be done for standalone implementation?

Thanks.

That's good idea, I've published OPUS codec (fixed point number version) as Arduino library https://github.com/sh123/esp32_opus_arduino (also added into Arduino libraries registry), loopback i2s example (record->encode->decode->playback) works OK for the first glance, will try to add it to this project.

Thank you very much.

Added OPUS, could be selected between Codec2/OPUS from settings, seems to work between two transceivers, but did not test very extensively.
