I created this 11 second clip in Ableton Live, using the granular synthesis method.
The initial sample was a single keystroke on a piano, which was sped up and then pitched down, keeping its shortened length.
Then, the sample was chopped into various small pieces, with which three different waves of sound were created. Many effects came into play, but most notably – reverb, ring modulation, equalizer, filters – low and high passes, with automation on many of the effects.
I will upload more original audio demonstrations later on.
