Zusammenfassung:A first playback stream presentation intended for reproduction on a first audio reproduction system and transform parameters may be received and decoded. The second playback stream presentation may be intended for reproduction on headphones. The transform parameters may be applied to an intermediate playback stream presentation to obtain the second playback stream presentation. The intermediate playback stream presentation may be the first playback stream presentation, a downmix of the first playback stream presentation, or an upmix of the first playback stream presentation. A cross-talk-cancelled signal may be obtained by processing the second playback stream presentation with a cross-talk cancellation algorithm. The cross-talk-cancelled signal may be processed by a dynamic equalization or gain stage wherein an amount of equalization or gain may be dependent on a level of the first playback stream presentation or the second playback stream presentation.
