Program Audio Switch serves for overlapping between various audio sources on PC computer, i.e. it can alternatively toggle on/off audibility of two or more audio sources. As it allows hearing of only one sound at a time, the program can best serve for audible comparison of different recordings of the same song. For example:

1. comparison of grabbing quality from audio CDs (CD Copy, Easy CD Extractor, ...) as it can simultaneously play the reproduction from CD and the very same song previously grabbed in Wav format;

2. comparison of the noise removal quality from gramophone records performed by various programs (Cool Edit Pro, Sound Forge, ...); at the same time the songs can be reproduced in Wav format obtained by those programs;

3. comparison of compression quality of different compressors (Xing, Fraunhofer, ...), various types of compression (Layer III, Twin VQ, AAC, ...) and various bit-rates (128 kb/s, 192 kb/s, ...),....

Program Audio Switch can operate in two ways: 1) by overlapping between Wave Out and Aux (CD Audio, Line In, ...) sound source, and 2) by overlapping between more (up to 9) instances of WinAMP program.

Overlapping of various audio sources by Audio Switch program can be performed manually by pressing one button or letting the computer perform automatic periodical overlapping with set time interval. The order of switching of certain audio sources can be sequential or random.

Audio Switch program can also serve for audio testing with statistic representation of results, especially in combination with automatic overlapping and random switching sequence.

Audio Switch program is 32-bit Windows application and it requires PC computer with installed Windows 95, 98, NT 4.0 or Win2000 operating system. For simultaneous reproduction of several audio sources, especially several compressed songs, the PC computer should have the fastest possible CPU (approx.: Pentium 100 MHz for one compressed song, Pentium 233 MMX for 2-3 compressed songs, ...). For program operation, a sound card is necessary, if possible one of those enabling simultaneous reproduction of several Wave sources.

If program option Switch between 9x WinAMP is going to be implemented, the corresponding program WinAMP should be installed, its version 2.0 or later. Program Audio Switch has been tested conclusively with WinAMP version 2.6.
