I still wonder how much lip sync went on with Pink's performance at the Grammys.
anyone evr really tried this thing? does it do it on real time?
http://en.wikipedia.org/wiki/VocoderThe vocoder examines speech by measuring how its spectral characteristics change over time. This results in a series of numbers representing these modified frequencies at any particular time as the user speaks. In simple terms, the signal is split into a number of frequency bands (the larger this number, the more accurate the analysis) and the level of signal present at each frequency band gives the instantaneous representation of the spectral energy content. Thus, the vocoder dramatically reduces the amount of information needed to store speech, from a complete recording to a series of numbers. To recreate speech, the vocoder simply reverses the process, processing a broadband noise source by passing it through a stage that filters the frequency content based on the originally recorded series of numbers.For musical applications, a source of musical sounds is used as the carrier, instead of extracting the fundamental frequency. For instance, one could use the sound of a synthesizer as the input to the filter bank, a technique that became popular in the 1970s.
Amazingly even in the 1980's an acquaintance who was a synthesizer enthusiast demoed this 'VoCoder' contraption to a friend and I, where you could speak or sing into a microphone, and press keys on the synthesizer (single notes or even full chords) and your voice would come out in that pitch.

If you remember that song that starts "Is this the real life....? Or is this fantasy?"
