My friend showed me this plug. The demo works fine in mono, you can also listen to the demo. http://www.soniccharge.com/bitspeek

I would like to create something similar. Obviously we have the down-sampling aspects covered courtesy of previous threads.

I am convinced I have played a Kyma sound that does 70% of what this plug does, I have been rummaging the re-synthesis and vocoding patches, yet have not quite found what I am looking for.

'Linear prediction' on the private forums did not turn up any gems.

Suggestions welcomed, sorry if re-treading old ground..
:-)

P.S. Topic Fail: Bitspeek

Oh apparently Frequency and Time Scaling is where I should of been looking...

Perhaps Vocoder would be worth experimenting with?

Also, when creating a gallery from within the TAU editor, there are patches that use oscillators with amplitude/timing/pitch/formant from a PSI file, so loading a vocal in there & clicking on "gallery" might give you half of the bitspeek. The LPC is not accounted for, though, there's no equivalent to that in Kyma that I'd be aware of.

I am sure harnessing the potential of analysis and oscillator banks via TAU or otherwise has to be the way forward, I am still shakey on the terminology.

I decided to stop being lazy and read around a little.

Hmm, from reading that first article, the basic technique used for LPC is pretty similar to the RE/EX resynthesis, the EX file representing the glottal pulse (or "buzzer" in that article), the RE file doing the formant filtering (the "tube" in that article). For the data reduction effect, you could used short loops in the RE/EX files that step through the file (equivalent to the article's "frames per second").
