Abstract

A system for processing digitally-encoded audio data comprising a compressed audio source device providing a sequence of frames of compressed digital audio data. A compressed audio enhancement system configured to receive the sequence of frames of compressed digital audio data and to generate enhanced audio data by adding masked digital audio data to the sequence of frames of compressed digital audio data, where the masked digital audio data has an energy level sufficient to keep a kinocilia of a listener active. One or more speakers configured to receive the enhanced audio data and to generate sound waves using the enhanced audio data.
