#X text 18 26 Input sound is analyzed and a certain number of bin snapshots
are taken \, based on the probability and framegrains parameters. Each
bin grain snapshot is sent out as a list with two members: [amplitude
\, frequency]. In this example the grain data is used to drive a sample
player. One could easily replace this with a synth or even drive an
external MIDI synth. This is something like a pitch-follower except
that it follows the entire spectrum (limited by the topfreq parameter)
rather than just looking for the fundamental. Since this is based on
FFT analysis the resolution is worse for lower frequencies. Frequency
resolution can be improved by upping the FFT size.;
