Abstract: Systems and methods are provided for utilizing a heterogeneous computing platform of an IHS (Information Handling System) to identify an audio headset worn by a user of the IHS. An orchestrator device of the IHS uses resources of the heterogeneous computing platform to capture a plurality of images of a user of the IHS, such as using integrated and/or external cameras of the IHS. Based on the captured images of the user, a determination is made regarding whether the user is wearing an audio headset and the audio headset worn by the user is identified. The IHS is then configured for audio outputs to the identified audio headset worn by the user.

Abstract: An audio headset receives one or more audio signals carrying one or more audio channels and processes the audio channels to generate stereo signals for output to a left and a right speaker of the audio headset. The processing determines a number of the audio channels carried in the received audio signal(s), adjusts level(s) of the audio channels based on the determined number of audio channels and/or adjusts gain and/or phase of the audio channels to control a perceived location of a listener wearing the headset relative to a source of sounds carried in the stereo signals.

Abstract: Methods and systems are provided for matrixed audio settings. In an audio system that includes at least one audio output element for outputting audio signals, a first user input that includes a selection of audio mode may be received, and based on the selected audio mode and pre-set mapping data, one or more audio settings from a plurality of audio settings supported in the system may be determined, for use during generating, processing, and/or outputting of the audio signals. The mapping data defines for each supported audio mode valid values for each of corresponding one or more audio settings from the plurality of audio settings. At least one user control element may be configured to enable receiving a second user input that includes a selection between the determined one or more corresponding audio settings. The audio system, or at least the audio output element thereof, may be a headset.

Abstract: The present disclosure relates to reverberation generation for headphone virtualization. A method of generating one or more components of a binaural room impulse response (BRIR) for headphone virtualization is described. In the method, directionally-controlled reflections are generated, wherein directionally-controlled reflections impart a desired perceptual cue to an audio input signal corresponding to a sound source location. Then at least the generated reflections are combined to obtain the one or more components of the BRIR. Corresponding system and computer program products are described as well.

Abstract: A virtual stereo synthesis method includes acquiring at least one sound input signal on a first side and at least one sound input signal on a second side, separately performing ratio processing on a preset head related transfer function (HRTF) left-ear component and a preset HRTF right-ear component of each sound input signal on the second side, to obtain a filtering function of each sound input signal on the second side, separately performing convolution filtering on each sound input signal on the second side and the filtering function of the sound input signal on the second side, to obtain the filtered signal on the second side, and synthesizing all of the sound input signals on the first side and all of the filtered signals on the second side into a virtual stereo signal where the method may alleviate a coloration effect, and reduce calculation complexity.

Abstract: An audio-signal processing device includes a decoding unit that decodes a compressed audio stream to obtain audio signals for a predetermined number of channels; a signal processing unit that generates 2-channel audio signals including left-channel audio signals and right-channel audio signals, on the basis of the predetermined-number-of-channels audio signals; and a coefficient setting unit that sets filter coefficients corresponding to the impulse responses for the digital filters, on the basis of format information of the compressed audio stream. The signal processing unit uses digital filters to convolve impulse responses for paths from sound-source positions of the channels to the left and right ears of a listener with the corresponding predetermined-number-of-channels audio signals and adds corresponding results of the convolutions for the channels to generate the left-channel audio signals and the right-channel audio signals.
