Publication number: 20230209302Abstract: An audio apparatus for generating a diffuse reverberation signal comprises a receiver (501) 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 (505, 507) 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 (509) 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.Type: ApplicationFiled: June 21, 2021Publication date: June 29, 2023Inventors: Jeroen Gerardus Henricus KOPPENS, Patrick KECHICHIAN
