NAME

           mkss
          - calculate average spectrum for spectral subtraction

SYNOPSIS

       mkss [options...] {filename}

DESCRIPTION

       mkss is a tool to estimate noise spectrum for spectral subtraction on
       Julius. It reads a few seconds of sound data from microphone input,
       calculate the average spectrum and save it to a file. The output file
       can be used as a noise spectrum data in Julius (option "-ssload").

       The recording will start immediately after startup. Sampling format is
       16bit, monoral. If outpue file already exist, it will be overridden.

OPTIONS

        -freq  Hz
          Sampling frequency in Hz (default: 16,000)

        -len  msec
          capture length in milliseconds (default: 3000)

        -fsize  sample_num
          frame size in number of samples (default: 400)

        -fshift  sample_num
          frame shift in number of samples (default: 160)
