1. A method of decoding playback stream presentations from a data stream, the method comprising:
receiving and decoding a first rendered playback stream presentation, said first rendered playback stream presentation being a set of M1 signals intended for reproduction on a first audio reproduction system;
receiving and decoding a set of transform parameters suitable for transforming an intermediate playback stream presentation into an anechoic binaural presentation, wherein the intermediate playback stream presentation is one of the first rendered playback stream presentation, a down-mix of the first rendered playback stream presentation, and an up-mix of the first rendered playback stream presentation;
receiving one or more sets of dialogue signal estimation parameters suitable for transforming the intermediate playback stream presentation into one or more estimated dialogue signals;
applying said transform parameters to said intermediate playback stream presentation to produce the anechoic binaural presentation;
applying the one or more sets of dialogue estimation parameters to the intermediate playback stream presentation to generate the one or more estimated dialogue signals;
cancelling the one or more estimated dialogue signals from the intermediate playback stream presentation to produce one or more dialogue reduced signals;
applying the one or more dialogue reduced signals to one or more acoustic environment simulation processes to produce one or more simulated acoustic environment signals; and
combining the one or more simulated acoustic environment signals with the anechoic binaural presentation.
