nRF5340 LC3 Sample Rate

[gfgf2400a]

Hi,

From nRF5340 audio example kconfig, there is a note that "now 48kHz is the only sample rate supported". Is this correct? My application would only work for lower bitrate that required the lowest sample rate of 8kHz and 16 bit audio depth. Please clarify. Thanks, Dennis

Hi, 

See the CONFIG_AUDIO_SAMPLE_RATE_HZ:

I2S supports 16, 24, and 48 kHz sample rates for both input and output. USB supports only 48 kHz for input.

Regards,
Amanda H.

Hi,

And thank you for your support! I have tried to change the sample rate from 48kHz to 24kHz. When compiling, the code resets to the 48kHz sample rate - and my device has not changed any qualifications. 

Can the change in sample rate be done in any other way? And is there some other files that need to be changed?

I regards, thank you
