External Master Clock vs I2S
Using ADAU1772, we create a Master Clock with our fpga. It is a little off, 12.262 MHz. I did not change anything in the PLL SigmaStudio tab, wrote the EEPROM with the fpga, and we got the intended si

Is it possible to offload FIR processing to the RPi 4 NEON SIMD from the ADAU1701?
So my thought is this: since the Sharc came out, there have been advances in process and architecture making the number of coefficients that can be processed through NEON on ARM greatly increased over
