    摘要： Some methods involve receiving, by a control system that is configured for implementing a plurality of renderers, audio data and listening configuration data for a plurality of listening configurations, each listening configuration of the plurality of listening configurations corresponding to a listening position and a listening orientation in an audio environment, and rendering, by each renderer and according to the listening configuration data, the received audio data to obtain a set of renderer-specific loudspeaker feed signals for a corresponding listening configuration. Each renderer may be configured to render the audio data for a different listening configuration. Some such methods may involve decomposing each set of renderer-specific loudspeaker feed signals into a renderer-specific set of frequency bands and combining the renderer-specific frequency bands of each renderer to produce an output set of loudspeaker feed signals.

    摘要： Some methods involve receiving, by a control system configured for implementing a plurality of Tenderers, audio data and listening configuration data for a plurality of listening configurations, each listening configuration of the plurality of listening configurations corresponding to a listening position and a listening orientation in an audio environment, and rendering, by each Tenderer and according to the listening configuration data, the received audio data to obtain a set of Tenderer-specific loudspeaker feed signals for a corresponding listening configuration. Each Tenderer may be configured to render the audio data for a different listening configuration. Some such methods may involve decomposing each set of renderer-specific loudspeaker feed signals into a Tenderer-specific set of frequency bands and combining the renderer-specific frequency bands of each Tenderer to produce an output set of loudspeaker feed signals. Some such methods may involve outputting the output set of loudspeaker feed signals to a plurality of loudspeakers.

    摘要： An audio processing method may involve receiving media input audio data corresponding to a media stream and headphone microphone input audio data, determining a media audio gain for at least one of a plurality of frequency bands of the media input audio data and determining a headphone microphone audio gain for at least one of a plurality of frequency bands of the headphone microphone input audio data. Determining the headphone microphone audio gain may involve determining a feedback risk control value, for at least one of the plurality of frequency bands, corresponding to a risk of headphone feedback between at least one external microphone of a headphone microphone system and at least one headphone speaker and determining a headphone microphone audio gain that will mitigate actual or potential headphone feedback in at least one of the plurality of frequency bands, based at least partly upon the feedback risk control value.

    摘要： Embodiments for a speaker system that produces a near-field sound pattern for rendering immersive audio content in a portable device. An array of drivers projects sound upwards from a top surface of the portable device to form upward-firing speakers; a set of speakers projects sound downwards from a bottom surface of the portable device to form downward-firing speakers. A decoder/renderer component receives immersive audio content, decodes height audio signals from the content and sends direct audio signals to the downward-firing speakers. A crossover performs a high-pass filter function to pass high frequency components of the decoded height audio signals to the upward-firing speakers and low frequency components of the decoded height audio signals to the downward-firing speakers.
