Abstract: An audio processing method may involve receiving audio signals and associated spatial data, listener position data, loudspeaker position data and loudspeaker orientation data, and rendering the audio data for reproduction, based, at least in part, on the spatial data, the listener position data, the loudspeaker position data and the loudspeaker orientation data, to produce rendered audio signals. The rendering may involve applying a loudspeaker orientation factor that tends to reduce a relative activation of a loudspeaker based, at least in part, on an increased loudspeaker orientation angle. In some examples, the rendering may involve modifying an effect of the loudspeaker orientation factor based, at least in part, on a loudspeaker importance metric. The loudspeaker importance metric may correspond to a loudspeaker's importance for rendering an audio signal at the audio signal's intended perceived spatial position.

Abstract: Systems, methods, and computer program products of preparing an audio signal for playback on a monaural playback device A system receives an audio signal including one or more components, the one or more components including sound from one or more audio sources. The system processes the audio signal to create a monaural signal. The processing includes introducing one or more monaural cues into at least one component of the one or more components. The monaural signal maintains a presence of the one or more monaural cues. The system then provides the monaural signal to the monaural playback device or to a storage device. The one or more monaural cues are such that, if the monaural signal is played back to a listener using the monaural playback device, the listener experiences a perceived differentiation in direction of the one or more components and/or the one or more audio sources.

Abstract: In some embodiments, a method for performing at least one of enhancement, decoding, or rendering of a multichannel audio signal in response to compression feedback or feedback from a smart amplifier. For example, the compression feedback may be indicative of amount of compression applied to each of multiple frequency bands, of the audio signal or an enhanced audio signal generated in response thereto. The enhancement (e.g., bass enhancement) may include dynamic routing of audio content of the input audio signal between channels of an enhanced audio signal generated in response thereto. The enhancement and compression may be performed on a per speaker class basis. 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 or laptop computer, tablet, soundbar, mobile phone, or other device with small speakers) configured to perform any embodiment of the method.

Abstract: Some implementations involve receiving a content stream that includes audio data, receiving at least one type of level adjustment indication relating to playback of the audio data and controlling a level of the input audio data, based on the at least one type of level adjustment indication, to produce level-adjusted audio data. Some examples involve determining, based at least in part on the type(s) of level adjustment indication, a multiband limiter configuration, applying the multiband limiter to the level-adjusted audio data, to produce multiband limited audio data and providing the multiband limited audio data to one or more audio reproduction transducers of an audio environment.

Abstract: A method of processing of a sequence of video frames from a camera capturing a writing surface for subsequent transmission to at least one of a remote videoconferencing client and a remote videoconferencing server. The method comprises receiving the sequence of video frames from the camera; and selecting an image area of interest in the video frames, comprising selecting one of a sub-area of the video frames and an entire area of the video frames. The method also comprises, for each current video frame of the sequence of video frames, generating a pen stroke mask by applying adaptive thresholding to the image area of interest. The method also comprises generating an output video frame using the pen stroke mask. Corresponding systems and computer readable media are disclosed.

Abstract: Some implementations involve determining a noise metric and/or a speech intelligibility metric and determining a compensation process corresponding to the noise metric and/or the speech intelligibility metric. The compensation process may involve altering a processing of audio data and/or applying a non-audio-based compensation method. In some examples, altering the processing of the audio data does not involve applying a broadband gain increase to the audio signals. Some examples involve applying the compensation process in an audio environment. Other examples involve determining compensation metadata corresponding to the compensation process and transmitting an encoded content stream that includes encoded compensation metadata, encoded video data and encoded audio data from a first device to one or more other devices.

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.
