Thanks for the prompt response.
I don't think I can use signals to store the samples though, right? Cause I need to store my data coming from the microphone into a memory, say like 8 samples of 32 bits. Then Call each sample, apply a filter and then read them back to the speakers when the specified control signals in the audio codec is set to high.

Okay, how does this look like? I added the read part a well.
