音频处理g

Hello Dialog team,

I'm trying to acquire data prom two PDM microphones and transmit it further (over USB to PC, or via SPI to SD card, or somwhere else).

In the apu_demo I found example, how to record one sample and process it, but documentation for APU is slightly unclear, so I'm not understand, how to process audio without stopping audio manager every time, when buffer is full. Can you share more applicable example, please?

Hi Egor,

Hi Egor,

Thanks for your question. With the current APU demo of the SDK, you can store data into QSPI flash. How to process audio without stopping audio manager every time, when buffer is full, is something that is not support in this example. However, I’ll ask internally if we have anything else to be shared.

Thanks, PM_Dialog
