USB Audio Example - 44100 Support

Question asked by dmann on May 20, 2011

Hello,

 

I am using a custom BF525 board that has a codec/cystal combination for a sample rate of 44.1kHz. I have had success in modifying the USB Audio example for the BF527 to work with our custom hardware, but the USB playback and record are still at the project default of 48KHz. So the USB audio sample rate is 48kHz, but the actual codec rate locked at 44.1K.

 

Can anyone provide some guidance on what changes might be necessary to modify the BF525/BF526 audio example to be in sync with a 44.1K codec that has no USB control mode? Are there any examples out there?

 

I had noticed that there was a #define for using 44_1 in one of the usb_audio source files, but was curious to whether or not this mode has been completed. 

 

Thanks,

 

Doug
