AudioListener.GetSpectrumData

static function GetSpectrumData (samples : float[], channel : int, window : FFTWindow) : void

Description

Returns a block of the listener (master)'s spectrum data

Number of values (numSamples) must be a power of 2. (ie 128/256/512 etc). Min = 64. Max = 8192. Use window to reduce leakage between frequency bins/bands. Note, the more complex window type, the better the quality, but reduced speed.
