SPECDRUNK takes a "random walk" through the analysis windows: it moves through the file file reading windows, but jumps backwards or forwards at random. The size of the random jumps cannot be greater than max_step. The process never reads backwards through the file and proceeds until the specified output duration has been generated. PARAMETERS max step Range (in windows) for the walk: maximum size of jump to next window. Leaps that would go beyond the file length are reflected back inside. Range: 1 - 64 (?) CDP
manual gives 64
max., but more is possible; however it's less than no.

OPTIONno repeats Ignore window repeats, i.e. steps of zero length. NOTES If the range (max step) is small (e.g. 10 windows), the output tends to linger around the start-point in the file, progressing very slowly away from it in an arbitrary direction. This results in a mix of time-stretching and slow wandering through the source. If large, the drunken walk tends to leap about wildly in the file, scrambling the source sound.
