A system and method is provided to produce a flatter frequency response from an audio source that has a non-flat frequency response and, as such, has missing spectral content. The system and method achieves a flatter frequency response by characterizing the frequency response of the audio source based upon a reference input signal. This reference input signal is used to establish a reference frequency response, which is stored in a memory and used to select equalizer settings. The system restores missing spectral content by way of summing multiple input signals from the audio source. The system then normalizes the frequency response based on characterizations of the signal by utilizing equalizer settings from memory.
