Returns

OutSpectrum - The resulting spectrum

Parameters

Parameter	Description
SoundWave	The wave to generate the spectrum for
Channel	The channel of the sound to calculate. Specify 0 to combine channels together
StartTime	The beginning of the window to calculate the spectrum of
TimeLength	The duration of the window to calculate the spectrum of
SpectrumWidth	How wide the spectrum is. The total samples in the window are divided evenly across the spectrum width.
