Abstract: A soundbar speaker for transmitting reflected sound waves off an upper surface down to a listening environment, comprising: a cabinet containing a plurality of audio drivers, direct-firing drivers within the cabinet oriented to transmit sound along a horizontal axis substantially perpendicular to a front surface of the cabinet, and a pair of upward-firing slotted drivers placed proximate to ends of an top surface of the cabinet and oriented at an inclination angle relative to the horizontal axis. The slotted drivers are configured to create an overlapping reflected sound projection for high frequency sound when reflected down to a listening position located at a distance in front of the speaker pair. Such a speaker projects reflected sound that provides wider horizontal or side-to-side dispersion to better cover the listening area.

Abstract: In some embodiments, a method for processing an audio signal in an audio processing apparatus is disclosed. The method includes receiving an audio signal and a parameter, the parameter indicating a location of an auditory event boundary. An audio portion between consecutive auditory event boundaries constitutes an auditory event. The method further includes applying a modification to the audio signal based in part on an occurrence of the auditory event. The parameter may be generated by monitoring a characteristic of the audio signal and identifying a change in the characteristic.

Abstract: Media input audio data corresponding to a media stream and microphone input audio data from at least one microphone may be received. A first level of at least one of a plurality of frequency bands of the media input audio data, as well as a second level of at least one of a plurality of frequency bands of the microphone input audio data, may be determined. Media output audio data and microphone output audio data may be produced by adjusting levels of one or more of the first and second plurality of frequency bands based on the perceived loudness of the microphone input audio data, of the microphone output audio data, of the media output audio data and the media input audio data. One or more processes may be modified upon receipt of a mode-switching indication.

Abstract: Embodiments are described for calibrating a speaker in a device having a microphone by inputting an original audio signal to a processing component and an output stage of the device for playback through the speakers, receiving playback sound output from the speakers through the microphone to generate a microphone signal, and inputting the microphone signal into the processing component to calibrate the speakers for optimal playback of the original audio signal, wherein the processing component is configured to compare the original audio signal to the microphone signal and correct the microphone signal by one or more audio processing functions in accordance with a refresh schedule.
