STM32F407 USB recording

I have tried STM32F407 pass through sample. It works well now, so I can play music to 3.5mm audio jack or  let microphone pass through to headphone.

I'm wondering if I can enable USB  path recording when I record sound from on board mems microphone  ?

thanks

Hi Jacky,

Yes, using a recording DAW like Audacity you could record sound from the mems microphone on your board.  With your board connected to your computer, you would just set your input to the mems microphone.

Thanks,

Hi Kevin

   Got it!  I only could fine AWE audio Class as output path, but there is no AWE audio audio Class as input path shown in windows control panel. How should I enable AWE audio Class input path that I can record sound from mems microphone on my board.

Thanks,

Jacky

Unfortunately, the STM32F407 BSP from DSP Concepts only implemented USB playback. You will not be able to do USB recording unless you modify the BSP firmware to support it.

Hi Chris,

   Understood! Have DSP concepts implement USB record on "STM32F769I" ?

Hi Jacky,

Yes USB record works on the STM32F769I, but you would need the correct BSP for that board.  I'll email you shortly to take this discussion offline.

Thanks,

Kevin
