Hi list,<br><br>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:
<br><br>- 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)?
<br><br>- 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?
<br><br>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.<br><br>RIch<br>
