Abstract: A method for generating a spatial audio stream, the method including: obtaining at least two audio signals from at least two microphones; extracting from the at least two audio signals a first audio signal, the first audio signal including at least partially speech of a user; extracting from the at least two audio signals a second audio signal, wherein speech of the user is substantially not present within the second audio signal; and encoding the first audio signal and the second audio signal to generate the spatial audio stream such that a rendering of speech of the user to a controllable direction and/or distance is enabled.

Abstract: A method for generating a parametric spatial audio stream, the method including: obtaining at least one mono-channel audio signal from at least one close microphone; obtaining at least one of: at least one reverberation parameter; at least one control parameter configured to control spatial features of the parametric spatial audio stream; generating, based on the at least one reverberation parameter, at least one reverberated audio signal from a respective at least one mono-channel audio signal; generating at least one spatial metadata parameter based on at least one of: the at least one mono-channel audio signal; the at least one reverberated audio signal; the at least one control parameter; and the at least one reverberation parameter; and encoding the at least one reverberated audio signal and the at least one spatial metadata parameter to generate the spatial audio stream.

Abstract: Examples of the disclosure relate to apparatus, methods and computer programs for spatial processing audio scenes with improved intelligibility for speech or other key sounds. In examples of the disclosure at least one audio signal including two or more channels is obtained. The audio signal is processed with program code to identify at least a first portion of the audio signal wherein the first portion predominantly includes audio of interest. The first portion is processed using a first process. The second portion is processed using a second process including spatial audio processing. The first process includes no spatial audio processing or a low level of spatial audio processing compared to the second process and the second portion predominantly includes a remainder. The processed first portion and second portion can be played back using two or more loudspeakers.

Abstract: Examples of the disclosure relate to speech enhancement that can be adapted for varying sound scenes. In examples of the disclosure a control parameter for speech enhancement is obtained. The control parameter indicates a user preference for speech enhancement. One or more audio signals are obtained and the one or more audio signals are processed to determine a sound classification based at least on the one or more audio signals. The control parameter and the sound classification are used to determine a processing parameter. Speech enhancement is enabled on the one or more audio signals. The speech enhancement uses the processing parameter such that the processing parameter is configured to control proportions of speech and remainder in an output signal.

Abstract: An apparatus for generating a spatialized audio output based on a listener position, the apparatus including circuitry configured to: obtain two or more audio signal sets; obtain a listener position within an audio environment, wherein the audio environment includes one or more area having one or more inside and outside regions in relation to the respective audio signal set positions; obtain metadata based on a processing of the at least two audio signals; determine, for the listener position within an audio environment outside the inside region, a second listener position; determine modified metadata for the second listener position based on the metadata; determine at least two modified audio signals for the second listener position based on the at least two audio signals; determine spatial metadata for the listener position; and output the at least two modified audio signals and the spatial metadata.

Abstract: Examples of the disclosure relate to apparatus, methods and computer programs for repositioning spatial audio streams. The apparatus is configured to receive a plurality of spatial audio streams wherein the spatial audio streams include one or more audio signals and associated spatial metadata. The apparatus is also configured to receive obtaining repositioning information relating to at least one of the plurality of spatial audio streams and repositioning the at least one of the plurality of spatial audio streams based on the repositioning information.

Abstract: An apparatus for spatial audio signal decoding associated with a plurality of speaker nodes (201, 203, 205, 207, 209) placed within a three dimensional space, the apparatus comprising at least one processor and at least one memory including a computer program code. The at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to determine a non-overlapping virtual surface arrangement (400), the virtual surface arrangement (400) comprising a plurality of virtual surfaces (421, 423, 431, 433) with corners positioned at at least three speaker nodes of the plurality of speaker nodes (201, 203, 205, 207, 209) and sides connecting pairs of corners configured to be non-intersecting with at least one defined virtual plane within the three dimensional space.
