MKSS(1)

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
Sampling frequency (Hz, default=16000) length to record in milliseconds (default: 3000). frame size in number of samples (default: 400). frame shift in number of samples (default: 160).

USAGE
Start mkss and stay quiet for 3 seconds. Then the average noise spectrum will be recorded to the specified file. When you start Julius, specify option "-ssload thatfile", and you can use microphone input with spectral subtraction.
