Summary:A spectral tilt of an audio signal is used to determine whether a speaker will introduce perceptible distortion during playback of the audio signal. The spectral tilt may be indicated by determining a ratio between energy in a distortion-producing frequency band and energy in a distortion-masking frequency band. Based on the determined spectral tilt, the distortion-producing frequency band may be attenuated to reduce the distortion introduced by the speaker. Additionally, the distortion-masking frequency band may be amplified to reduce perceptibility of the distortion produced by the speaker.
