For the 16 gpio in parallel in dma mode: can we go above 56Khz? what would be the maximum khz?

it depends on your algorithms - how fast you process
16 i2s/dma channels - will take data down to 40 mhz. minimum 2 samples per bit -- 20 mhz, but you won't have time to process this stream

So finally it can work for 16 I2S/DMA channels for simultaneous 15Mhz per IR receiver?
The processing can be done by the other Core while the first is dedicated to the sampling
Does it makes sense?

I do not have an answer to this question, you can try,
take the data and see the time of their processing

if necessary ring buffer and continuous flow is made
