public static function GetSpectrumData(numSamples: int, channel: int, window: FFTWindow): float[];
public static float[] GetSpectrumData(int numSamples, int channel, FFTWindow window);

Parameters

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.
