ABSTRACT:
An adjustable CODEC receives a signal and compresses a received audio signal based on a psycho-acoustic compression system. The psycho-acoustic compression system includes several psycho-acoustic parameters which may be adjusted by the user to optimize the compression system for a specific application, transmission medium, or end user, for example. The compression and the adjustment of compression parameters may occur simultaneously in real time without interruption of the compressed signal. Additionally, the parameters may be adjusted in smart groups of a plurality of parameters that are, for example, sympathetic or are often adjusted together. An additional signal may also be combined with the compressed signal and the resultant combined signal may be transmitted over a single transmission path. For example, the additional signal may be multiplexed into the compressed data stream for TDMA transmission. Additionally, the parameters selected at a local, user-adjusted CODEC may be transmitted to a plurality of remote CODEC for remote use.
