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.
