Sound Examples

These examples are intended for demonstrating various audio signal encoding techniques and their effect on sound quality. The examples are in WAV, MP3 and Ogg Vorbis format.

Suitable programs for playing the example are xmms for Linux (www.xmms.org), QuickTime Player for MacOS, and Winamp for MS Windows (www.winamp.com), among others. For playing Ogg Vorbis files, a Vorbis plug-in may be needed (see www.vorbis.com).
