Thank you

It preserves color of the voice (timbre) while pitch shifting so you
don't sound like you inhaled helium on higher pitch factors.

It is related to frequency.
I calculated it as diff=abs((df-f)/f), where df is desired frequency
and f is current frequency, and then that diff is compared to
threshold.

Currently it is:
0 - chromatic scale
1 - C major (white keys on piano)
2 - pentatonic scale
3 - harmonic E minor

Scales are defined in scales.xml file and can easily be added. When I
find some time I will add more of them. Also in one of next versions I
plan to make better GUI so that scale can be chosen by name.
