ABSTRACT:
A transform based compression mechanism to establish a single compression technique which is applicable for all audio compression ranging from very low bit rate speech to CD/Audio quality music. Additionally, a multiconferencing unit (multi-point bridge) is provided which takes advantage of the transform based compression algorithm by providing a simple, low cost way of combining multiple parties without the need for transcoding.
