Audio object separation from mixture signal using object-specific time/frequency resolutions |
摘要 |
An audio decoder is proposed for decoding a multi-object audio signal consisting of a downmix signal X and side information PSI. The side information comprises object-specific side information PSI i for an audio object s i in a time/frequency region R(t R ,f R ), and object-specific time/frequency resolution information TFRI i indicative of an object-specific time/frequency resolution TFR h of the object-specific side information for the audio object s i in the time/frequency region R(t R ,f R ). The audio decoder comprises an object-specific time/frequency resolution determiner 110 configured to determine the object-specific time/frequency resolution information TFRI i from the side information PSI for the audio object s i . The audio decoder further comprises an object separator 120 configured to separate the audio object s i from the downmix signal X using the object-specific side information in accordance with the object-specific time/frequency resolution TFRI i . A corresponding encoder and corresponding methods for decoding or encoding are also described. |
