Another quickie:
What's the best way to tell a biquad filter "do nothing right now", i.e. pass all samples unchanged? Is there a preferred arrangement of the coefficients for that? I tried setting a lowpass filter with the cutoff frequency at 50khz, but it didn't work for some reason -- it still filtered audibly. (And even if it had worked, it would have been burning CPU for no reason.)
Thanks for any advice,
