DIRECTIONAL LOUDNESS MAP BASED AUDIO PROCESSING

DIRECTIONAL LOUDNESS MAP BASED AUDIO PROCESSING

An audio encoder (300) for encoding (310) an input audio content (112) comprising one or more input audio signals (112, 1121, 1122, 112s, 112a, 112b). The audio encoder (300) is configured to provide one or more encoded audio signals (320) on the basis of one or more input audio signals (112, 1121,...

Beschreibung
Zusammenfassung:An audio encoder (300) for encoding (310) an input audio content (112) comprising one or more input audio signals (112, 1121, 1122, 112s, 112a, 112b). The audio encoder (300) is configured to provide one or more encoded audio signals (320) on the basis of one or more input audio signals (112, 1121, 1122, 1123, 112a, 112b), or one or more signals derived therefrom (110, 1101, 1102, 110a, 110b). Additionally, the audio encoder (300) is configured to adapt (340) encoding parameters in dependence on one or more directional loudness maps which represent loudness information (142, 1421, 1422, 142a, 142b) associated with a plurality of different directions (121) of the one or more signals to be encoded.
