The downmix signal encodes two or more audio object signals. The decoder has a window-sequence generator for determining a plurality of analysis windows, each having a plurality of time-domain downmix samples of the downmix signal and a window length indicating the number of the time-domain downmix samples. Moreover, the decoder has a t/f-analysis module for transforming the plurality of time-domain downmix samples of each analysis window from a time-domain to a time-frequency domain depending on the window length of said analysis window, to obtain a transformed downmix. Furthermore, the decoder has an un-mixing unit for un-mixing the transformed downmix based on parametric side information on the two or more audio object signals to obtain the audio output signal. Moreover, an encoder is provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encoder, decoder and methods for backward compatible dynamic adaption of time/frequency resolution spatial-audio-object-coding","description":"A decoder for generating an audio output signal having one or more audio output channels from a downmix signal having a plurality of time-domain downmix samples is provided.
