Abstract: Audio systems and methods are provided that enhance a portion of audio content relative to other portions of the audio content. The systems and methods select the portion to be enhanced and calculate an intelligibility metric of the selected portion, such as a dialogue portion. The systems and methods determine a gain based at least in part upon the intelligibility metric and apply the gain to the selected portion to provide an enhanced portion. The systems and methods provide an audio signal, based at least in part upon the enhanced portion, to an output for conversion to an acoustic signal, such as by an acoustic transducer.

Abstract: An audio system with first and second discrete audio drivers that are in a listening space, wherein each driver is configured to radiate sound into the listening space, and wherein the radiated sound from each driver at a listening location in the listening space has a frequency, phase, and magnitude. The audio system is configured to modify a phase of the sound radiated by at least one of the first or second drivers such that a phase response difference between the first and second drivers at the listening location is closer to zero degrees than it was before the modification.

Abstract: Audio systems and methods are provided that receive a playback signal and produce an acoustic signal based upon the playback signal, and include microphone signal(s) for capturing and processing user voice signals. An echo reference signal is based upon the playback signal, and an echo canceler reduces echo components from the microphone signal(s). Functionality of the echo canceler is modified, such as by freezing an adaptive filter, in response to a non-linear condition in the audio playback, or a likelihood of such a non-linear condition.

Abstract: Audio speaker systems and methods are provided to detect movement of the speaker system or other device. An audio program content signal is converted into an acoustic signal, and the acoustic signal causes an echo signal. The echo signal is received and a relationship of the echo signal to the audio program content signal is quantified. A quantified value is compared to a stored quantified value and, based upon the comparison, a change in physical position is selectively indicated.

Abstract: Processing a signal includes: receiving data that includes an input signal; filtering the input signal to generate a filtered signal, such that if the input signal includes at least one instance of a nonlinear distortion of a desired signal then the filtered signal includes a signature signal corresponding to the nonlinear distortion, the nonlinear distortion characterized by a time duration that is within a predetermined range; and detecting whether or not the filtered signal includes the signature signal.
