Voice synthesis on ISR

Yes! Now at least for me this gives much better HW/result value. Good job!

Speech is as good as before, greetings! Your player with voice effects should find place in games and demos.
Great work!

All in all seems like black magic to me

Wouldn't it be great to add this to the AGD engine?

For a singing voice, since it has a single pitch, if you take the IDFT at the fundamental frequency to produce the waveform, do you need more than a single SCC channel? Since an SCC waveform can convey up to 16 harmonics (ignoring stepping noise) it seems to me like it should be able to reproduce the formants with relative accuracy… What are the additional channels used for?

So you would scan over an array of fundamental frequency + waveform for each frame, 2040 bytes/s. The waveforms can perhaps be shared when their DFT is similar to reduce the storage requirements.

I wonder how it would sound, seems like it should be fairly good due to the high rate and accurate reproduction of the pitch, but maybe it’ll be a bit autotune-ey :). Still cool. Good for Cher :P.

No, the idea is to use the wave form to better match the spectral maxima without using other channels
At the time I have fiddled around this concept without any acceptable result.
One of the problems was that usually the speech had more formants at not multiple frequencies.
The advantage would be that you leave the other channels free.
I will return on the subject if have time.
