  • Publication number: 20190174246
    Abstract: A spatial audio processing apparatus comprises a receiver (101) for receiving audio scene data describing an audio scene comprising spatial audio components and associated position data. The audio components may be provided as audio objects. A distance unit (105) provides a position indication which includes a focus distance that is indicative of a distance from a reference position in the audio scene. An adapter (103) adapts a perceptual emphasis property, such as an audio level, frequency distribution, or degree of diffuseness, of a spatial audio component relative to at least one other spatial audio component of the audio scene in response to a difference measure reflecting a difference between the focus distance and a distance in the audio scene from the reference position to a position of the spatial audio component. An audio renderer (107) renders the resulting audio scene using the received position data. The approach may emphasize audio at the focus distance in the audio scene.

  • Publication number: 20180192222
    Abstract: An audio signal processing apparatus comprises a receiver (101) which receives an audio signal comprising audio data for at least a first audio object associated with a three dimensional image. The audio signal also comprises depth position data indicative of a target depth position for the first audio object. A determiner (107) determines a visual rendering depth range for a target three dimensional display for presenting the three dimensional image and a mapper (109) for mapping the target depth position to a rendering depth position for the audio object where the mapping is dependent on the visual rendering depth range. The visual rendering depth range may specifically be a depth range in which the three dimensional display can accurately render objects and the mapper (109) may amend the positions of audio object sound sources such that these match the depth positions of corresponding visual objects presented by the three dimensional display.

  • Publication number: 20160241984
    Abstract: An audio apparatus generates drive signals for a plurality of loudspeakers (101) and comprises a receiver (103) for receiving an audio signal. A divider (105) divides typically a low frequency part of the audio signal into a plurality of audio subbands thereby providing a subband signal for each audio subband of the audio subbands. An analyzer (109) generates acoustic room response indications for each loudspeaker (101) for at least one subband. The indications may be indicative of a coupling of the individual loudspeaker to any room resonances in the individual subbands. A generator (107) generates the drive signals from the subband signals with the generator (107) being arranged to distribute at least a first subband signal of a first subband to the drive signals in response to the acoustic room response indications for the first subband.

  • Patent number: 9332371
    Abstract: A system for determining loudspeaker position estimates comprises motion sensors (201,203) and a movement processor (205) arranged to determine motion data for a user movable unit where the motion data characterizes movement of the user moveable unit. A user input interface (207) receives user inputs and a user processor (209) processes them into user activations which indicate that at least one of a current position and orientation of the user movable unit is associated with a loudspeaker position. An analyzing processor (211) then generates loudspeaker position estimates in response to the motion data and the user activations. The system thus performs speaker position estimations based on (i) the motion data of the user moveable unit being pointed towards or positioned on a speaker and (ii) the user activations.

  • Patent number: 9282417
    Abstract: An apparatus for spatial sound reproduction comprises a receiver (101) for receiving a multi-channel audio signal. An analyzer (107) determines a spatial property of the multi-channel audio signal, such as a spatial complexity or organization. A selection processor (109) then selects a reproduction mode from a plurality of sound reproduction modes where the multi-channel sound reproduction modes employ different spatial rendering techniques. A reproduction circuit (103) then drives a set of loudspeakers (105) to reproduce the multi-channel audio signal using the selected reproduction mode. The switching between the reproduction modes may be fast (e.g. in the order of 100 ms to 10 secs) thereby allowing a short term adaptation of the reproduction mode to the signal characteristics. The approach may in particular provide an improved spatial experience to a listener.

  • Publication number: 20150358756
    Abstract: An audio apparatus comprises a receiver (201) which receives an audio signal. A generator (203) generates a multi-channel signal including a primary signal and a secondary signal. For example, the multi-channel signal may include a center speech signal and an ambient signal. A driver (205) generates drive signals for a set of loudspeakers (109-15) which for a loudspeaker will include at least a first signal component from the primary 5 signal and a second signal component from the secondary signal. A position circuit (207) determines the position of the loudspeaker (109) and the driver (205) adjusts a level of the primary signal component relative to a level of the secondary signal component in response to the first position relative to a reference position. The approach may allow automated adaptation of the audio rendering to specific loudspeaker configurations and may in particular 10 support optimized rendering for a plurality of listening zones.

  • Patent number: 9036841
    Abstract: A speaker system includes a first speaker (203) and a second speaker (205). A driving circuit receives an audio signal and has a first drive circuit (209) generating a first drive signal for the first speaker (203) in response to a first filtering of the audio signal with a first passband. A second drive circuit (211) generates a second drive signal for the second speaker (205) in response to a second filtering having a second passband which includes a frequency band below the first passband. A delay (213) delays the second drive signal relative to the first drive signal. The sound from the second speaker is directionally radiated with a directional radiation pattern having a notch towards the listening position (111). The system uses the precedence effect and non-direct low frequency audio radiation to ensure that directional cues are predominantly provided by the first speaker (203) which may be small and positioned remote from the second speaker (205).

  • Patent number: 8837743
    Abstract: A surround sound system comprises a receiver (301) for receiving a multichannel spatial signal that comprises at least one surround channel. A directional ultrasound transducer (305) is used for emitting ultrasound towards a surface to reach a listening position (111) via a reflection of the surface. The ultrasound signal may specifically reach the listening position from the side, above or behind of a nominal listener. A first drive unit (303) generates a drive signal for the directional ultrasound transducer (301) from the surround channel. The use of an ultrasound transducer for providing the surround sound signal provides an improved spatial experience while allowing the speaker to be located e.g. to the front of the user. In particular, an ultrasound beam is much narrower and well defined than conventional audio beams and can accordingly better be directed to provide the desired reflections. In some scenarios, the ultrasound transducer (305) may be supplemented by an audio range loudspeaker (309).
