Well, that depends, because if the transfer functions differ

a lot, then you might get clicks, as the resulting waveform

might have a big jump between samples. If however you are

using well-behaved polynomials, then the difference between

the curves might be smooth enough. Also remember that

by just drawing transfer functions it is very easy to get

non-bandlimited signals. Polynomials are generally your

best bet.

Subject: [Csnd] dynamic wavetables, was: phase shaping

 

All this talk about phase shaping and rewriting tables got me thinking.

Is there something hindering us from algorithmically rewriting wavetables on the fly ?

I figure, if the rewriting is happening at the exact same rate as the table reading, we would not get unwanted clicks or discontinuities.

Or ?
