Replacing/Bypassing Audio codec on the nrf5340 Audio DK

[sudha_mqa]

Hello!

As part of a development initiative we are trying to use the nRF5340 Audio DK and run a different codec on it, bypassing the LC3 altogether. This new codec will be built using the existing toolchain on the chip and linked in to the build. 

Can you please suggest how we can go about this? Most forums have recommended this as the best place to go

Thank you!

Hi Sudha,

It is indeed possible to use software codecs other than the LC3 or SBC.. There is a middle layer for that.. You will need to check and update:

applications/nrf5340_audio/src/audio/sw_codec_select.h 

applications/nrf5340_audio/src/audio/sw_codec_select.c

Best Regards,

Swathy

Thank you. However, this audio needs to be sent over bluetooth and the packet size varies from that of LC3. What changes need to be made in the bluetooth layer to do this?
