摘要： An encoder (1201) for encoding a pluralityofaudio signals comprises a selector (1303) which selects a subset of time-frequency tiles to be downmixed and a subset oftiles to be non-downmix. A downmix indication is generated which indicates whether tiles are encoded as downmixed encoded tiles or as non-downmixtiles. An encoded signal comprising the encoded tiles and the downmix indication is fed to a decoder (1203) which includes a receiver (1401) for receiving the signal. A generator (1403) generates output signals from the encoded time-frequency tiles where the generation of the output signals includes an upmixing for tiles that are indicated by the downmix indication to be encoded downmixed tiles. The invention may provide more flexible and/or improved encoding/ decoding and may specifically provide improved scalability, especially at higher data rates.
