Class Methods

*new(sfpath)

sfpath - the path for a mono sound file to analyze

Instance Methods

ana(filPath, fftSize, winType, hop)

filPath - the path to save the analysis to

fftSize - size of the FFT - should be a power of two (default: 2048)

winType - the FFT window type (see FFT - default is 1, Hann)

hop - the amount of offset from one FFT analysis frame to the next, measured in multiples of the 

analysis frame size. Defaults to 0.25.

Usage:

a = PVAna.new("sounds/a11wlk01.wav");

a.ana("sounds/a11wlk01.scpv", 2048, 1, 0.25);
