mkss - compute average spectrum from mic input for SS

NAME
       mkss - compute average spectrum from mic input for SS
 
SYNOPSIS
       mkss [options..] filename
 
DESCRIPTION
       mkss  is  a tool for estimating noise spectrum for spectral subtraction
       on Julius.  It reads a few seconds of sound data from microphone input,
       and  saves the average spectrum to a file.  The output file can be used
       as a noise spectrum data in Julius (option "-ssload").
 
       Output format is RAW (no header), 16bit  (signed  short,  big  endian),
       monoral.  If the file already exist, it will be overridden.
 
OPTIONS
       -freq threshold
              Sampling frequency (Hz, default=16000)
 
       -len msec
              length to record in milliseconds (default: 3000).
 
       -fsize samplenum
              frame size in number of samples (default: 400).
 
       -fshift samplenum
              frame shift in number of samples (default: 160).
 
USAGE
       Start  mkss and stay quiet for 3 seconds.  Then the average noise spec-
       trum will be recorded to the specified file.  When  you  start  Julius,
       specify  option  "-ssload  thatfile",  and you can use microphone input
       with spectral subtraction.
