Example techniques involve outputting multiple audio channels using a multiple driver playback device. An example playback device receives a first and second channel of audio content. The playback device plays back play back the first channel via a first group of audio transducers such that the first group of audio transducers form, via superposition, a first response lobe having a maximum in a first direction. Further, the playback device plays back the second channel via a second group of audio transducers such that the second group of audio transducers form, via superposition, a second response lobe having a maximum in a second direction that is separated by an angle of at least 45° from the first direction.

The present disclosure relates to reverberation generation for headphone virtualization. A method of generating one or more components of a binaural room impulse response (BRIR) for headphone virtualization is described. In the method, directionally-controlled reflections are generated, wherein directionally-controlled reflections impart a desired perceptual cue to an audio input signal corresponding to a sound source location. Then at least the generated reflections are combined to obtain the one or more components of the BRIR. Corresponding system and computer program products are described as well.

A combined ambient sound and secondary audio system comprises at least one microphone for receiving ambient sound, at least one receiver for receiving secondary audio from a secondary audio source not audible in the ambient sound. The system further includes a memory storing one or more sets processing parameters comprising instructions for processing the ambient sound and the secondary audio and a processor coupled to the memory, the microphone, and the receiver configured to generate combined ambient and secondary sound by combining the ambient sound and the secondary audio as directed by a selected set of processing parameters retrieved from the memory.

An audiovisual communication system includes a plurality of environment sound sources, a microphone array, an image processing device, an audio processing device and a denoise processing device. Each of the plurality of environment sound sources has an environment sound. A plurality of microphones of the microphone array receive the plurality of environment sounds and output a plurality of receiving audio signals according to the plurality of environment sounds respectively. The image processing device obtains an image including the plurality of environment sound sources and selects one of the plurality of environment sound sources in the image as a target sound source according to a selection command. The image processing device calculates a relative position between the target sound source and the microphone array according to a first coordinate. The audio processing device receives the plurality of receiving audio signals and calculates a target audio signal.

An audio reproduction system for reproducing audio data of at least one audio object and/or at least one sound source of an acoustic scene in a given environment comprising: at least two audio systems acting distantly apart from each other, wherein one of the audio systems is adapted to reproduce the audio object and/or the sound source in a first distance range to a listener and another of the audio systems is adapted to reproduce the audio object and/or the sound source in a second distance range to the listener, wherein the first and second distance ranges are different and possibly spaced apart from each other or placed adjacent to each other; and a panning information provider adapted to process at least one input to generate at least one panning information for each audio system to drive the at least two audio systems.

A device for generating a multitude of loudspeaker signals based on a virtual source object which has a source signal and a meta information determining a position or type of the virtual source object. The device has a modifier configured to time-varyingly modify the meta information. In addition, the device has a renderer configured to transfer the virtual source object and the modified meta information to form a multitude of loudspeaker signals.
