Embodiment Construction

[0049]Examples of the present disclosure relate to an apparatus 101 , method and computer program for controlling noise reduction in an audio signal comprising audio captured by a plurality of microphones. The apparatus 101 comprises means for obtaining 301 one or more audio signals comprising audio captured by a plurality of microphones 203 and dividing 303 the obtained one or more audio signals into a plurality of intervals . The apparatus may also be configured to determine 305 one or more parameters related to one or more noise characteristics of different intervals, and to control 307 the application of noise reduction.

[0050] Thus, the apparatus 101 may enable different noise reduction methods to be applied to different intervals within the obtained audio signal. This may take into account differences in the perceptibility of noise in different frequency bands, the perceptibility of switching between different noise reduction methods in different frequency bands, and...

Abstract

Examples of the disclosure relate to apparatuses, methods and computer programs for controlling noise reduction in audio signals comprising audio captured by a plurality of microphones. The apparatus comprises a means for obtaining one or more audio signals, wherein the one or more audio signals comprise audio captured by a plurality of microphones and divides the obtained one or more audio signals into a plurality of intervals. The means may also be configured for determining one or more parameters relating to one or more noise characteristics for different intervals and controlling noise reduction applied to the different intervals based on the determined one or more parameters within the different intervals.

Description

technical field [0001] Examples of the present disclosure relate to apparatuses, methods and computer programs for controlling noise reduction. Some relate to apparatus, methods and computer programs for controlling noise reduction in an audio signal including audio captured by a plurality of microphones. Background technique [0002] An audio signal comprising audio captured by multiple microphones may be used to provide a spatial audio signal to a user. The quality of these signals can be adversely affected by unwanted noise captured by multiple microphones. Contents of the invention [0003] According to various but not all examples of the present disclosure, there is provided an apparatus comprising means for: obtaining one or more audio signals, wherein the one or more audio signals comprise audio; dividing the obtained one or more audio signals into a plurality of intervals; determining one or more parameters related to the one or more noise characteristics of the ...
