Question about pvsanal and pvspitch

1. pvsanal outputs an fsig. What is an fsig?
2. does pitchtrack output a number every k period or does it do an analysis from beginning to end?

Many thanks for help.

An fsig is a variable type

An fsig is a variable type to contain spectral data. It is updated every time a new window is requested. fsigs start with an f character.

Not sure i understand Q2: it will analyse a window at a time (unless sliding). Certainly these are on-the-fly opcodes and so not beginning to end analysis
