Abstract
An audio decoder is proposed for decoding a multi-object audio signal including a downmix signal X and side information PSI. The side information includes object-specific side information PSIfor an audio object sin a time/frequency region R(t,f), and object-specific time/frequency resolution information TFRIindicative of an object-specific time/frequency resolution TFRof the object-specific side information for the audio object sin the time/frequency region R(t,f). The audio decoder includes an object-specific time/frequency resolution determinerconfigured to determine the object-specific time/frequency resolution information TFRIfrom the side information PSI for the audio object s. The audio decoder further includes an object separatorconfigured to separate the audio object sfrom the downmix signal X using the object-specific side information in accordance with the object-specific time/frequency resolution TFRI. A corresponding encoder and corresponding methods for decoding or encoding are also described.
