摘要： Arrangement for distributing head related transfer function filters. In the arrangement a user device sends a request for a head related transfer function filter to the service being used. The service verifies if the user of the device has a subscription for a head related transfer function filters in the service being used and retrieves a filter as a response to a positive verification result. The service may filter audio channels and transmit filtered audio further. In an alternative embodiment the service transmits the filter to the user device for filtering the audio.

摘要： This disclosure provides methods, devices, and systems for speech enhancement. The present implementations more specifically relate to utilizing multiple modalities to suppress audio originating from a distractor audio source without distorting audio originating from a target audio source. In some aspects, a speech enhancement system may receive a multi-channel audio signal via a microphone array and may further receive an image associated with a respective frame of the audio signal. The speech enhancement system detects one or more target faces in the image and determines whether the audio frame originates from a target audio source. For example, the speech enhancement system may compare a respective direction of each target face with a direction-of-arrival (DOA) of the audio frame. The speech enhancement system may selectively steer a beam associated with a multi-channel beamformer toward the DOA of the audio frame based on whether the audio frame originates from a target face.

摘要： Multiple virtual source locations may be defined for a volume within which audio objects can move. A set-up process for rendering audio data may involve receiving reproduction speaker location data and pre-computing gain values for each of the virtual sources according to the reproduction speaker location data and each virtual source location. The gain values may be stored and used during “run time,” during which audio reproduction data are rendered for the speakers of the reproduction environment. During run time, for each audio object, contributions from virtual source locations within an area or volume defined by the audio object position data and the audio object size data may be computed. A set of gain values for each output channel of the reproduction environment may be computed based, at least in part, on the computed contributions. Each output channel may correspond to at least one reproduction speaker of the reproduction environment.

摘要： A system 3 synchronises a plurality of virtual reality headsets 2 to corresponding multichannel audio. System 3 has a plurality of independently operable virtual reality headsets each having one or more images preloaded thereon and a distribution device 4 in the form of a server is in Wi-Fi communication via a wireless access point 5 with each virtual reality headset where the server 4 triggers the one or more preloaded images on each headset. A sound rack device 6 is in Wi-Fi communication with server 4 and configured to send time codes signals thereto. A sound mixer 7 is in cable communication with the sound rack device 6 and receives audio file data corresponding to virtual reality image content therefrom simultaneously with the server 4. The server 4 is cable connected to the wireless access point 5 and configured to simultaneously message each headset 2. At least one speaker element is provided for each channel of audio being connected to the mixer 7 such that upon receipt of the audio file, the mixer 7 is configured to relay each channel audio signal to respective speakers 8 in synchronisation with the VR headset images.
