  • Publication number: 20180151185
    Abstract: An audio encoder comprises a multi-channel receiver which receives an M-channel audio signal where M>2. A down-mix processor down-mixes the M-channel audio signal to a first stereo signal and associated parametric data and a spatial processor modifies the first stereo signal to generate a second stereo signal in response to the associated parametric data and spatial parameter data for a binaural perceptual transfer function, such as a Head Related Transfer Function (HRTF). The second stereo signal is a binaural signal and may specifically be a (3D) virtual spatial signal. An output data stream comprising the encoded data and the associated parametric data is generated by an encode processor and an output processor. The HRTF processing may allow the generation of a (3D) virtual spatial signal by conventional stereo decoders. A multi-channel decoder may reverse the process of the spatial processor to generate an improved quality multi-channel signal.

  • Patent number: 9973871
    Abstract: An audio renderer comprises a receiver (801) receiving input data comprising early part data indicative of an early part of a head related binaural transfer function; reverberation data indicative of a reverberation part of the transfer function; and a synchronization indication indicative of a time offset between the early part and the reverberation part. An early part circuit (803) generates an audio component by applying a binaural processing to an audio signal where the processing depends on the early part data. A reverberator (807) generates a second audio component by applying a reverberation processing to the audio signal where the reverberation processing depends on the reverberation data. A combiner (809) generates a signal of a binaural stereo signal by combining the two audio components. The relative timing of the audio components is adjusted based on the synchronization indication by a synchronizer (805) which specifically may be a delay.

  • Publication number: 20170125030
    Abstract: An encoder generates data representing an audio scene by a first downmix and data characterizing audio objects. In addition, a direction dependent diffuseness parameter indicative of a degree of diffuseness of a residual downmix is provided where the residual downmix corresponds to a downmix of audio components of the audio scene with the audio objects being removed. A rendering apparatus comprises a receiver receiving the data from the encoder. A circuit generates signals for a spatial speaker configuration from the audio objects. A transformer generates non-diffuse sound signals for the spatial speaker configuration by applying a first transformation to the residual downmix and another transformer generates signals for the spatial speaker configuration by applying a second transformation to the residual downmix by applying a decorrelation to the residual downmix. The transformations are dependent on the direction dependent diffuseness parameter. The signals are combined to generate an output signal.

  • Patent number: 9626975
    Abstract: An audio signal processor receives a plurality of encoded multi-channel audio signals. A multi-channel decoder (105) decodes a first encoded multi-channel signal to generate a first decoded multi-channel signal. A generator (109) generates an encoded further audio signal by selecting audio encoding data from at least a second encoded multi-channel audio signal such that a number of channels of the encoded further audio signal comprising audio encoding data from the second encoded multi-channel audio signal is less than a number of channels in the second encoded multi-channel signal. Thus, a channel reduction is performed in the encoded data domain. A further decoder (111) generates a further decoded signal by decoding the further encoded audio signal. A combiner (107) combines the first decoded multi-channel signal and the further decoded signal to generate a multi-channel output signal. An exciting user experience can be provided while maintaining low complexity and resource usage.

  • Patent number: 9478228
    Abstract: An encoder (1201) for encoding a plurality of audio signals comprises a selector (1303) which selects a subset of time-frequency tiles to be downmixed and a subset of tiles to be non-downmix. A downmix indication is generated which indicates whether tiles are encoded as downmixed encoded tiles or as non-downmix tiles. An encoded signal comprising the encoded tiles and the downmix indication is fed to a decoder (1203) which includes a receiver (1401) for receiving the signal. A generator (1403) generates output signals from the encoded time-frequency tiles where the generation of the output signals includes an upmixing for tiles that are indicated by the downmix indication to be encoded downmixed tiles. The invention may provide more flexible and/or improved encoding/decoding and may specifically provide improved scalability, especially at higher data rates.

  • Patent number: 9462387
    Abstract: An audio system comprises a receiver (301) for receiving an audio signal, such as an audio object or a signal of a channel of a spatial multi-channel signal. A binaural circuit (303) generates a binaural output signal by processing the audio signal. The processing is representative of a binaural transfer function providing a virtual sound source position for the audio signal. A measurement circuit (307) generating measurement data indicative of a characteristic of the acoustic environment and a determining circuit (311) determines an acoustic environment parameter in response to the measurement data. The acoustic environment parameter may typically be a reverberation parameter, such as a reverberation time. An adaptation circuit (313) adapts the binaural transfer function in response to the acoustic environment parameter. For example, the adaptation may modify a reverberation parameter to more closely resemble the reverberation characteristics of the acoustic environment.
