  1. Above filter_biquad(), I'd add what these xs and ys mean. Yes, you do follow the established standard naming convention when dealing with IIR filters, but not all pulseaudio hackers are DSP specialists. I.e. please add something like:

"Here x0, x1 and x2 are the most recent input sample, the previous one and the second-previous one. y0, y1 and y2 are the output samples corresponding to x0, x1 and x2." Ok.
