AudioLowPassFilter 音频低通滤波器

# AudioLowPassFilter 音频低通滤波器

Inherits from [Behaviour](../Behaviour/Behaviour.html)

The Audio Low Pass Filter filter passes low frequencies of an

AudioSource, or all sound reaching an AudioListener, and attenuates
frequencies higher than the Cutoff Frequency.

音频低通滤波器， 通过音频源的低频率，或所有声音达到 AudioListener，并且衰减频率比截止频率高。

> 音频低通滤波器（AudioLowPassFilter），它的用途是使低于某个特定频率的信号全部通过，而对高于此频率的成分予以衰减，其中这个特定的频率我们称之为截止频率（cutofffrequency）

Note: This filter is only available on the PRO version.

注意：AudioHighPassFilter 仅在专业版可用。

### Variables**变量**

* [cutoffFrequency](AudioLowPassFilter.cutoffFrequency.html)
  Lowpass cutoff frequency in hz. 10.0 to 22000.0. Default =
  5000.0.
  低通截止频率在 10.0～22000.0hz。默认=5000.0。
* [lowpassResonaceQ](AudioLowPassFilter.highpassResonaceQ.html)
  Determines how much the filter's self-resonance is
  dampened.
  定义了滤波器的自共振衰减多少。
