A binaural room impulse response (BRIR) can be generated based on a position of a listener's head, and a plurality of head related impulse responses (HRIRs). Each of the plurality of HRIRs are selected for a respective one of a plurality of acoustic reflections which, when taken together, approximate reverberation of a room. Each of the acoustic reflections have a direction and a delay. The BRIR filter is applied to source audio to generate binaural audio output.

Disclosed are an audio encoding method, to which BRIR/RIR parameterization is applied, and a method and device for reproducing audio by using parameterized BRIR/RIR information. The audio encoding method according to the present invention comprises the steps of: when an input audio signal is a binaural room impulse response (BRIR), dividing the input audio signal into a room impulse response (RIR) and a head-related impulse response (HRIR); applying a mixing time to the divided RIR or an RIR, which is input without division when the audio signal is the RIR, and dividing the mixing time-applied RIR into a direct/early reflection part and a late reverberation part; parameterizing a direct part characteristic on the basis of the divided direct/early reflection part; parameterizing an early reflection part characteristic on the basis of the divided direct/early reflection part; parameterizing a late reverberation part characteristic on the basis of the divided late reverberation part; and when the input audio signal is the BRIR, adding the divided HRIR and information of the parameterized RIR characteristic to an audio bitstream, and transmitting the same.

Disclosed herein are system, method, and computer program product embodiments for replicating a remote venue in a local venue. An embodiment operates by receiving original audio. Thereafter, the original stream of audio is modified to produce modified audio based on an audio profile unique to a remote venue smaller than the local venue. The audio profile comprises a virtual representation of the remote venue including (i) a virtual audio source corresponding to the local venue's audio source and configured to produce the original audio and (ii) a virtual reverberation point corresponding to a real-world location in the remote venue and the portion of the local venue. As such, the modified audio is determined based on receipt of the original audio from the reverberation point. Thus, after correlating the modified audio to the local venue's audio source, the modified audio is provided by the audio source to the portion of the local venue.

Apparatuses, methods and computer programs are described comprising: providing an incoming call indication in response to an incoming call, the incoming call indication including an initial ambient audio signal comprising a combination of first ambient audio and second ambient audio; receiving an ambient audio control command; and adjusting the initial ambient audio signal to generate an adjusted ambient audio signal depending on the ambient audio control command.

A method including receiving an audio scene including at least one source captured using at least one near field microphone and at least one far field microphone. The method includes determining at least one room-impulse-response associated with the audio scene based on the at least one near field microphone and the at least one far field microphone, accessing a predetermined scene geometry corresponding to the audio scene, and identifying best match to the predetermined scene geometry in a scene geometry database. The method also includes performing RIR comparison based on the at least one RIR and at least one geometric RIR associated with the best matching geometry and rendering a volumetric audio scene based on a result of the RIR comparison.

Determination of a set of acoustic parameters for a headset is presented herein. The set of acoustic parameters can be determined based on a virtual model of physical locations stored at a mapping server. The virtual model describes a plurality of spaces and acoustic properties of those spaces, wherein the location in the virtual model corresponds to a physical location of the headset. A location in the virtual model for the headset is determined based on information describing at least a portion of the local area received from the headset. The set of acoustic parameters associated with the physical location of the headset is determined based in part on the determined location in the virtual model and any acoustic parameters associated with the determined location. The headset presents audio content using the set of acoustic parameters received from the mapping server.

Methods and apparatus assist listeners in distinguishing between electronically generated binaural sound and physical environment sound while the listener wears a wearable electronic device that provides the binaural sound to the listener. The wearable electronic device generates a visual alert or audio alert when the electronically generated binaural sound occurs.

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.

An audio system, method, and computer program product which includes a wearable audio device and a mobile peripheral device. Each device is capable of determining its respective absolute or relative position and orientation. Once the relative positions and orientations between the devices are known, virtual sound sources are generated at fixed positions and orientations relative to the peripheral device such that any change in position and/or orientation of the peripheral device produces a proportional change in the position and/or orientation of the virtual sound sources. Additionally, first order and second order reflected audio paths may be simulated for each virtual sound source to increase the realism of the simulated sources. Each sound path can be produced by modifying the original audio signal using head-related transfer functions (HRTFs) to simulate audio as though it were perceived by the user's left and right ears as coming from each virtual sound source.
