I would like to use my STM32F746G-Discovery board as a stereo effect unit. I have used STM32Cube to initialize the audio codec. How do I implement a callback routine that reads stereo data from line-in and processes it to line-out through an audio buffer? I want to use 32-bit bitdepth and 96kHz samplerate. I want the callback routine to run automatically and continiously and to have an optional buffer length to be able to control the latency. Thanks in advance.
