Abstract: Systems and methods for automatic characterization of perceived transducer distortion are described. The system includes a controller configured to receive a distortion level; a signal generator configured to generate a test signal for a frequency band in response to the distortion level, the test signal including at least two simultaneous tones, the at least two simultaneous tones having different frequencies within the frequency band; an audio transducer configured to generate an audio signal based on the test signal; and a distortion tuner configured to receive the audio signal and to determine the distortion level of the system based on a detected amount of distortion in the audio signal.

Abstract: In some embodiments, a method for performing enhancement on an audio signal to generate an enhanced audio signal in response to feedback indicative of amount of compression applied to at least one frequency band of the enhanced audio signal. In typical embodiments, the enhancement is or includes bass enhancement. Examples of other types of enhancement performed in other embodiments include dialog enhancement, upmixing, frequency shifting, harmonic injection or transposition, subharmonic injection, virtualization, and equalization Other aspects are systems (e.g., programmed processors) and devices (e.g., devices having physically-limited bass reproduction capabilities, such as, for example, a notebook, tablet, mobile phone, or other device with small speakers) configured to perform any embodiment of the method.
