The software product is built at support of the grant of Ministry of education of Russian Federation Т02-03.1-816.

Purpose: the program is intended for an evaluation of quality of a method of a scrambling used at problem solving of a guard of audio information.

Capabilities:
1. Recording of input audiosignal and noise interference for consequent analysis.
2. Loading ready acoustical files, one of which acts in a role speech audio-signal, and second - noise interference.
3. Ploting the chart maps of a spectrum input audio-signal and noise interference in a understandable simple view for a consequent evaluation by the user.
4. To calculate values of a signal-to-noise ratio, quotient of perception, information quantity and intelligibility audio-signal as on each frequency, on which one the research, and as a whole on all audio-signals were conducted.
5. To conduct an evaluation of quality of a scrambling it is ground of received performances, according to the Governmental Standart 50840 /29/.
6. To variate the established by default values of frequencies, thereby variating data-ins, that allows during activity to effect more detail analysis and evaluation.
