Abstract
An audio apparatus for generating a diffuse reverberation signal comprises a receiver () receiving audio signals representing sound sources and metadata comprising a diffuse reverberation signal to total source relationship indicative of a level of diffuse reverberation sound relative to total emitted sound in the environment. The metadata also for each audio signal comprises a signal level indication and a directivity data indicative of directivity of sound radiation from the sound source represented by the audio signal. A circuit () determines a total emitted energy indication based on the signal level indication and the directivity data, and a downmix coefficient based on the total emitted energy and the diffuse reverberation signal to total signal relationship. A downmixer () generates a downmix signal by combining signal components for each audio signal generated by applying the downmix coefficient for each audio signal to the audio signal. A reverberator () generates the diffuse reverberation signal for the environment from the downmix signal component.
