SOX-LOWPASS

[GENERIC-FUNCTION]


OM-SoX
Function Reference
ARGUMENTS:
  - cutoff-frequency Cutoff-frequency (Hz) [default = 1000]
  - width Filter width (applies only to two-pole filters). Default unit: Hz [default = 100]
  - poles One- or Two-pole filtering [default = "onepole"]
&key
 
  - unit Select unit for bandwidth value (Hz/kHz/Octaves/Q-factor). Defaults to Hz. [default = "Hz"]
  - sox-append Append sox-effects/statistics to the processing chain.  

Description:

Apply a low-pass filter to the audio.

Optional single-pole or double-pole filtering.
A value of Q = 0.707 for 'width' yields a Butterworth response.
