[PD] Converting PCM to delta sigma

[Martin Dupras]

I was wondering if anyone has tried converting PCM signals to
delta-sigma and vice-versa in PD? Are there any examples of how one
would do that?

To be clear, I don't need it to be realtime as such; what I'd like to
do is be able to copy the PCM values of one array as a delta-sigma
version in another.

Any ideas or pointers?

Thanks,
