    摘要: A headset accessory comprises circuitry and is configured to mechanically attach to an audio headset. The circuitry of the headset may be operable to establish a link to the audio headset that supports conveyance of bias voltage, bias current, and/or information between the circuitry of the accessory and circuitry of the audio headset. The headset accessory may be configured to attach to a housing of the headset on a surface of the housing opposite an ear cup. A state of the circuitry of the accessory may be controlled based on the information received from the audio headset via the link. The information may include characteristics of audio being processed by the audio headset. The circuitry of the headset accessory may comprise non-volatile memory, and the non-volatile memory may store parameter settings for configuring audio processing circuitry of the audio headset.

    摘要: Methods and systems for designing binaural room impulse responses (BRIRs) for use in headphone virtualizers, and methods and systems for generating a binaural signal in response to a set of channels of a multi-channel audio signal, including by applying a BRIR to each channel of the set, thereby generating filtered signals, and combining the filtered signals to generate the binaural signal, where each BRIR has been designed in accordance with an embodiment of the design method. Other aspects are audio processing units configured to perform any embodiment of the inventive method. In accordance with some embodiments, BRIR design is formulated as a numerical optimization problem based on a simulation model (which generates candidate BRIRs) and at least one objective function (which evaluates each candidate BRIR), and includes identification of a best one of the candidate BRIRs as indicated by performance metrics determined for the candidate BRIRs by each objective function.

    摘要: A computer-implemented method for generating spatial audio with uniform reverberation in a real-time communication session is performed by a real-time communication software application running on an electronic communication device. The method includes removing the reverberation of recorded speech signals from far-end participants by the dereverberation approach, rendering the direct sound parts by filtering the output signals by head-related transfer functions of desired directions, generating reverberant sound parts by convolving the output signals from with uniform room impulse responses or an artificial reverberator, combining direct and reverberant sound components to generate spatialized speech signals. When speakers and listeners are located in two virtual conference rooms, the reverberation of the two rooms are coupled. The reverberant sound parts are then generated by convolving the output signals and coupled RIRs from the two rooms.
