An audio digital CODEC is provided with various parameters that when changed affect the quality of the resultant audio. These psycho-acoustic parameters include the standard ISO parameters and additional parameters to aid in effecting a pure resulting audio quality. The psycho-acoustic parameters located in the audio digital CODEC can be monitored and controlled by the user. The parameters can be monitored by a speaker associated with the CODEC or headphones. The user can control the adjustment of the psycho-acoustic parameters through the use of knobs present on the front panel of the CODEC or graphic or digital representations. Adjustment of the parameters will provide real time change of the resulting audio sound that the user can monitor through the speaker or the headphones. Dynamic Psycho-acoustic Parameter Adjustment permits the user to dynamically chance the values of different parameters. The ability to chance the parameters can be embodied in front panel knobs or in the action of computer software as instructed by the user.

[ What is claimed is:] [1.]1. An audio CODEC for providing high quality digital audio comprising:an input for receiving an audio signal;an encoder connected to said input, said encoder having a plurality of conventional ISO/MPEG layer-II psycho-acoustic parameters, and a plurality of additional joint-stereo psycho-acoustic parameters, said encoder encoding said audio signal into a compressed digital signal in accordance with said plurality of joint stereo psycho-acoustic parameters along with said conventional ISO/MPEG layer-II psycho-acoustic parameters, each of said joint-stereo psycho-acoustic parameters being selectively programably adjustable by a user for adjusting a compressing of said compressed digital signal; anda decoder for decompressing said compressed digital signal into a digital audio output.
