New Post: 10 band Equalizer

I'm trying to create a 10 band EQ (frequency based; beginning at 32hz, ending at 16khz). I found BiQuadFilter.PeakingEQ, but I cannot figure out what the "q" parameter is supposed to be.

Is it the peak width? If so, what is the best way to implement? Overlapping peaks?

Is PeakingEQ what I should be using or is there a better option?
