    摘要： A decoder for generating an un-mixed audio signal comprising a plurality of un-mixed audio channels is provided. Moreover, an encoder and an encoded audio signal is provided. The decoder comprises an un-mixing-information determiner for determining un-mixing information by receiving first parametric side information on the at least one audio object signal and second parametric side information on the at least one audio object signal, wherein the frequency resolution of the second parametric side information is higher than the frequency resolution of the first parametric side information. Moreover, the decoder comprises an un-mix module for applying the un-mixing information on a downmix signal, indicating a downmix of at least one audio object signal, to obtain an un-mixed audio signal comprising the plurality of un-mixed audio channels. The un-mixing-information determiner is configured to determine the un-mixing information by modifying the first parametric information and the second parametric information to obtain modified parametric information, such that the modified parametric information has a frequency resolution which is higher than the first frequency resolution.

    摘要： A decoder for generating an audio output signal comprising one or more audio output Channels from a downmix signal comprising three or more downmix Channels, wherein the downmix signal encodes three or more audio object Signals is provided. The decoder comprises an input Channel router (110) for receiving the three or more downmix Channels and for receiving side information, and at least two Channel processing units (121, 122) for generating at least two processed Channels to obtain the one or more audio output Channels. The input Channel router (110) is configured to feed each of at least two of the three or more downmix Channels into at least one of the at least two Channel processing units (121, 122), so that each of the at least two Channel processing units receives one or more of the three or more downmix Channels, and so that each of the at least two Channel processing units (121, 122) receives less than the total number of the three or more downmix Channels. Each Channel processing unit of the at least two Channel processing units (121, 122) is configured to generate one or more of the at least two processed Channels depending on the side information and depending on said one or more of the at least two of the three or more downmix Channels received by said Channel processing unit from the input Channel router.
