I was looking at the miniSharc DSP board and realised that you can put multiple processing chains in series by feeding an I2S output back into an I2S input. You could e.g. use 1 chain for overall processing and next split into 1 chain per driver for driver specific processing. After some thinking I got to the following question: is there any benefit in daisy chaining 2 or more FIR filters? I think not, because: if you have a FIR filter per driver output, you can better assign the memory/taps to 1 FIR filter (per output). This way you get more correction potential (lower frequencies) at the same or less latency. Right?
