Environmental sound is recorded using one or more microphones. A source of the recorded environmental sound is classified. The recorded environmental sound is weighted based on the classification of the source and the source media sound using a weighting mode to determine whether to mix the recorded environmental. The recorded environmental sound is mixed with source media sound to produce a mixed sound based on the determination. The mixed sound is played over one or more speakers.

The application relates to an apparatus, method and computer program for representing a sound space for use in mediated reality applications. The apparatus including circuitry configured for: obtaining one or more values for one or more acoustic parameters for a plurality of locations within a sound space; and generating an image file representing the sound space where an intensity value for a pixel represents the value for an acoustic parameter at a location corresponding to the pixel such that the data in the image file enables the sound space to be rendered.

An audio mixer includes a reception portion and a controller. The reception portion receives a user's operation. The controller performs: display processing that displays a screen indicating a correspondence between a plurality of channels and a bus on a display; and setting processing that, when a specific operation is received through the reception portion and the channel is specified, associates the specified channel with a specific bus and outputs signals other than a signal of the associated channel from the specific bus.

Improved methods and/or apparatus for decoding an encoded audio signal in soundfield format for L loudspeakers. The method and/or apparatus can render an Ambisonics format audio signal to 2D loudspeaker setup(s) based on a rendering matrix. The rendering matrix has elements based on loudspeaker positions and wherein the rendering matrix is determined based on weighting at least an element of a first matrix with a weighting factor g=1/√{square root over (L)}.
