I wouldn't call it a vocoder yet. "Vocoder core" comes closer,
as it's only the filterbanks, VCAs and envelope followers
that make the core of a vocoder. The naked veroboard which was
shown on the picture some weeks ago. Nothing like voiced/unvoiced
detection, or silence bridging yet - this will be added of course.
What - you're telling us that you get that degree of speech
intelligibility ∗without∗ voiced/unvoiced decoder ??
Yes, and without mixing in part of the speech signal or any other
tricks that were used by some of the classic vocoders.
As for the samples, see them as a snapshot of the current state of
development, nothing more. A good friend of mine (who designed
the MAM vocoder) came to visit, and we played and tweaked
around all evening, and I had a DAT running and extracted a few
mp3 sniplets.
The number of bands is rather limited at the moment, too.
(Though the one who counted seven some weeks ago was way
wrong.)
The MOTM version is intended to have considerably more
channels. The idea is that I'm playing around and optimizing
a rather small vocoder, so the big one will be designed
without much unpleasant surprises.
And yes, I have just told you that you only heard the small one
so far (;->).
