1. A method for adaptive variable bit rate audio compression encoding comprising the steps of:

  • examining an audio level of a single frame of an audio signal from at least one sub-band filter in at least one encoder;

    detecting information in the single frame of examined audio level;

    retrieving the detected information from the single frame of examined audio level of the at least one sub-band filter;

    applying the retrieved information to a digital signal processor device for processing the information;

    comparing the processed information in a software program with a psycho-acoustic model in the at least one encoder;

    the at least one encoder assigning a bit rate to said single frame based on the compared audio data.
