Abstract

Typical audio compression/decompression systems require a software application or browser plugin on the end user's computer because their decompression requires a great deal of processing, particularly of series of trigonometric functions. The invention provides a method and system in which audio data is decompressed using simple linear operations, which allows music quality audio to be decompressed in real time. This also allows the decompression to be performed in a Java environment, so executable audio applets can be posted on Web sites, and be universally accessible.
