摘要：
Systems and methods for pre-conditioning a received audio signal prior to audio equalization of the audio signal are provided. The system (100) includes a spectral tilt estimator (110) for estimating a spectral tilt of the received audio signal, and a compensative filter synthesizer (115) for synthesizing a compensative filter based upon the spectral tilt estimated by the spectral tilt estimator. The filter comprises at least one compensative filter coefficient for mitigating the spectral tilt of the received audio signal prior to audio equalization of the audio signal.
