Hey srtuss, what planet are you from? This is amazing!

...In the case of this Ditty, the band-filtering and envelope-following of the modulator signal has been precomputed, and stored as an array. These amplitude fluctuations can then be played back like a tape. Since the original "vocals" are already a robot voice, it can be encoded at a very low resolution and still sound very close to the original.

Thanks for the comment! It works on the principle of a vocoder. A vocoder is a device that takes 2 input signals, "modulator" and "carrier" which it both splits up into an array of frequency bands, by filters. The vocoder tracks the amplitude of each modulator band, following it's envelope. Then the volume of each carrier band gets controlled by that envelope. In effect, the formant or "vowel" of the modulator gets superimposed onto the carrier. Typically the modulator is human voice, and the carrier is synthesizer sound, which creates the impression of the synthesizer speaking the words.

Wow! How does this work? Where is all the data? And how does a filter transforms a noisy sound into a sample?
