AudioSource.GetSpectrumData 获取声谱数据

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

Description描述

Returns a block of the currently playing source's spectrum data

返回当前播放源的声谱数据块。

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.

取样值必须是2的幂（如128/256/512等）。最小=64，最大=8192。使用FFTWindow以减少泄漏，频谱在bins/bands之间。注意，更复杂的窗型，质量越好，但减慢速度。
