ReadonlybinFrequency spacing between neighbouring bins
ReadonlysampleReadonlywindowNumber of bins in a spectrum (windowSize / 2 + 1)
The average of the spectra starting at several times — a steadier read than one window, e.g. a few reads just after an attack.
The frequency of a bin
The magnitude spectrum of the window starting at startFrame.
Samples past the end of the signal read as silence.
The magnitude spectrum of the window starting at a time in milliseconds
Magnitude spectra of a signal at arbitrary positions.
One FFT and window are built per analyser and reused for every read, so reading many positions of a long take is cheap.
