Function Reference
ARGUMENTS:
  - mode Mode: lowpass, highpass, band-pass, band-reject [default = "bandpass"]
  - low-boundary Low-Boundary frequency (in Hz) [default = 0]
  - high-boundary High-Boundary frequency (in Hz) [default = 20000]
&key
 
  - attenuation Stop-band attenuation (in db, between 40 and 180) [default = 120]
  - transition-bandwidth Transition bandwidth (in Hz)  
  - filter-taps Number of filter taps  
  - kaiser-beta Beta value for Kaiser window  
  - sox-append Append sox-effects/statistics to the processing chain.  

Description:

Apply a sinc kaiser-windowed low-pass, high-pass, band-pass, or band-reject FIR filter with 120dB stopband attenuation.

The default stop-band attenuation of 120dB can be overridden via <attenuation>.
Alternatively, the kaiser-window 'beta' parameter can be given directly via <kaiser-beta>.
The default transition band-width of 5% of the total band can be overridden with <transition-bandwidth> (in Hz).
Alternatively, the number of filter taps can be given directly via <filter-taps>.
