STM32H7 Audio Interface Programming in C

Firstly you MUST have an STM32H7 development board of some type, and experience with programming C/C++ using CubeIDE. PLEASE DO NOT APPLY IF YOU DO NOT HAVE THIS - YOU ARE WASTING YOUR TIME I want to use an STM32H7 device (actually the STM32H7B0VBT6 but all H7s are similar) to create an audio interface multiplexor. The H7 receives six channels of I2S based 96kHz 32bit audio through the I2S1, I2S2, I2S3, I2S6 and SAI2(2 data pins = 2 channels) from ADC convertors. The H7 is the master, ADCs the slave. SAI1 is then used in TDM slave mode to transfer 4 channels of 96kHz 32bit audio through each of the two SAI data pins, these being the six I2S channels and two spare for future use. The whole STM32H7 is fed from a master 12.288 MHz clock and an external 96kHz clock to which all data is synchronised. Obviously a lot more details will be needed to complete the task but looking for people who have done this sort of thing before as it's not easy.
