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)
