METHOD AND SYSTEM OF AUDIO POWER REDUCTION AND THERMAL MITIGATION USING PSYCHOACOUSTIC TECHNIQUES

摘要

Method of audio power reduction and thermal mitigation using psychoacoustic techniques starts by receiving a decoded audio signal in a reproduction system. Decoded audio signal is a signal that is decompressed and to be played back by a speaker. A masking curve is generated based on psychoacoustic models and the decoded audio signal. The masking curve is applied to the decoded audio signal to remove unheard frequencies and to generate a power-reduced audio signal. Other embodiments are also described.
