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: The present technique relates to an information processing device, an information processing method, and a program that allow a user to adjust a personalized transfer function.
The information processing device according to the present technique comprises an adjustment unit that adjusts personalized transfer characteristics, which are transfer characteristics of sound in a measurement environment and are personalized to a user, in response to an operation performed by the user. The information processing device according to the present technique further comprises a presentation unit that presents, to the user, contents of reference information referred to at the time of adjusting the personalized transfer characteristics, along with the personalized transfer characteristics.

摘要: In some embodiments, virtualization methods for generating a binaural signal in response to channels of a multi-channel audio signal, which apply a binaural room impulse response (BRIR) to each channel including by using at least one feedback delay network (FDN) to apply a common late reverberation to a downmix of the channels. In some embodiments, input signal channels are processed in a first processing path to apply to each channel a direct response and early reflection portion of a single-channel BRIR for the channel, and the downmix of the channels is processed in a second processing path including at least one FDN which applies the common late reverberation. Typically, the common late reverberation emulates collective macro attributes of late reverberation portions of at least some of the single-channel BRIRs. Other aspects are headphone virtualizers configured to perform any embodiment of the method.

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.

摘要: Techniques for calibrating listening devices are disclosed herein. The techniques include emitting a predetermined audio signal using an outward-facing transducer located on a first portion of a head-mounted device worn by the user, receiving the predetermined audio signal at a microphone located on a second portion of the head-mounted device, the second portion being different from the first portion, determining a transfer function for the user based on the received predetermined audio signal, and applying the transfer function to audio signals transmitted to the user.

摘要: Various embodiments set forth techniques for directional sound modification. In one aspect, a system includes a plurality of audio sensors configured to acquire sound from an environment and at least one processor coupled to the plurality of audio sensors. The at least one processor is configured to determine a direction within the environment, generate an audio signal based on sound acquired from the direction within the environment, and transmit the audio signal to at least one audio output device to generate audio output. The audio output combines with sound from the direction within the environment to produce a modified sound.
