Channel-Optimized Multiple-Description Scalar Quantizer Examples

Please note that these .wav files are not compressed. The average streaming rate required to play them is 705,600 bits/second so they may not play well at your site. If that is the case, you can create a local version of the demo by clicking here to download demo.zip to a local machine, unzipping it, and running demo.htm.
