I see the problem and I'm thinking I'm going to need to pull some CVS 
updates from the Nyquist repository.  But, still checking...

Roger, sorry to email you directly, but I just need to ask about the 
snd-biquad function.

It looks to me like the snd-biquadfilt function was renamed to 
snd-biquad in the 3.02 release, but it wasn't changed in dspprims.lsp. 
Or it was going to be changed to snd-biquadfilt but didn't make it into 
tran/biquadfilt*.
