Embodiments relate to binaural spatialization of more than two sound sources on two audio channels of an audio system. Sound signals each emitted from a corresponding sound source are collected, and a respective virtual position within an angular range of a sound scene is assigned to each sound source. Multi-source audio signals are generated by panning each sound signal according to the respective virtual position. A first multi-source audio signal is spatialized to a first direction to generate a first left signal and a first right signal. A second multi-source audio signal is spatialized to a second direction to generate a second left signal and a second right signal. A binaural signal is generated using the first left signal, the second left signal, the first right signal, and the second right signal. The binaural signal is such that each sound source appears to originate from its respective virtual position.

An apparatus comprising at least one processor and at least one memory, the memory comprising machine-readable instructions, that when executed cause the apparatus to: store in a non-volatile memory multiple sets of predetermined spatial audio processing parameters for differently moving sound sources; provide in a man machine interface an option for a user to select one of the stored multiple sets of predetermined spatial audio processing parameters for differently moving sound sources; and in response to the user selecting one of the stored multiple sets of predetermined spatial audio processing parameters for differently moving sound sources, the apparatus is further caused to use the selected one of the stored multiple sets of predetermined spatial audio processing parameters to spatially process audio from one or more sound sources.

A method and corresponding system for correcting for deviations in a performance that includes a plurality of audio sources, the method comprising detecting a parameter relating to an audio source, determining if the parameter deviates from a predetermined characteristic and in response to it being determined that the parameter deviates from the predetermined characteristic, causing display of a user interface configured to control the parameter, to allow a user to correct the deviation.

Apparatus is configured to associate each of one or more spatially-distributed audio sources in a virtual space, each audio source providing one or more audio signals representing audio for playback through a user device, with a respective fade-in profile which defines how audio volume for the audio source is gradually increased from a minimum level to a target volume level as a function of time. It is configured also to identify, based on user position, a current field-of-view within a virtual space and, in response to detecting that one or more new audio sources have a predetermined relationship with respect to the current field-of-view, fading-in the audio from the or each new audio source according to the fade-in profile for the respective audio source so as to increase their volume gradually towards the target volume level defined by the fade-in profile.

The present technology relates to an acoustic signal processing apparatus, an acoustic signal processing method, and a program for expanding a range of listening positions in which an effect of a transaural reproduction system can be obtained. First and second output signals for localizing a sound image in front of or behind and on the left of a first position located on the left of a listening position are output from first and second speakers, respectively. Third and fourth output signals for localizing a sound image in front of or behind and on the right of a second position located on the right of the listening position are output from third and fourth speakers, respectively. The first speaker is disposed in a first direction in front of or behind the listening position and on the left of the listening position. The second speaker is disposed in the first direction and on the right of the listening position. The third speaker is disposed in the first direction and on the left of the listening position and on the right of the first speaker. The fourth speaker is disposed in the first direction of the listening position and on the right of the second speaker. The present technology can be applied, for example, to an acoustic processing system.

This specification describes a method comprising determining whether an estimated position of an audio capture device which captures audio data is within boundaries of a predetermined area, and in response to a determination that the estimated position is not within the boundaries of the predetermined area, associating the captured audio data with an adjusted position.
