Abstract

A system for processing audio data is provided. The system includes a spectral shaping system that receives sample audio data and adaptive gain dat and generates spectral characteristic data for one or more spectral bands. The system also includes an audio processing system that receives the spectral characteristic data and which processes the audio data so as to provide the spectral characteristic data for the spectral bands of the audio data.
