Rich, I think you are writing to the wrong list :-) We can probably help
you with the SMS stuff if you
formulate it in general terms but not so much with pd internals ;-)

Hi list,
I've been working on getting a real-time spectral-model synthesizer
going, so far it handles 1TRC SDIF files quite well! Now I am onto
synthesizing the noise residual, but want to ask a couple questions
first:
- Is there any other processing that needs to be done to the 1STF
data, or is it ready to hand to [ifft~] as is? I assume that I need
to apply a window first, but maybe this is already done. Also, would
pd's [rifft~] suffice (It adds the second half of the fft by symmetry)?
- With the partial data, I interpolate the frequencies for every
sample because I am handed a frame for roughly every 10ms. However, a
1STF frame should cover 512 samples, which is roughly the same time.
Should I just set pd's blocksize to the fft size and send it a new
1STF frame every time I synthesize a new 1TRC frame, or will I need to
interpolate the 1STF data to get smooth transitions still?
If you can help clarify these issues for me, it is much appreciated.
Sorry if it is listed somewhere in Serra's publications, or in the
code. I looked, couldn't find what I needed to know.
