This is a minimum introduction to computer system Signal Workshop. This system was developed for forensic acoustics investigations. The main acoustics (signal) components this system deals with are so named sonoobjects. Each type of sonoobject has special properties. Expert can select some sonoobjects by their traces on dynamic spectrogram and then separate them, delete, gain there power (loudness) or listen separately.
Phase-amplitude spectra films and there main properties.
Some new properties and resolutions of sound traces.
Selecting and hearing some voice overtones traces.
