1. A method for dialogue enhancing audio content having one or more audio components, wherein each component is associated with a spatial location, comprising:
receiving a first audio signal presentation of the audio components intended for reproduction on a first audio reproduction system;
receiving a first set of presentation transform parameters configured to enable transformation of said first audio signal presentation into said second audio signal presentation intended for reproduction on a second audio reproduction system;
receiving a second set of presentation transform parameters configured to enable transformation of said first audio signal presentation into an acoustic environment simulation input signal;
receiving a set of dialogue estimation parameters configured to enable estimation of dialogue components from the first audio signal presentation;
applying the first set of presentation transform parameters to the first audio signal presentation to form the second audio signal presentation;
applying the second set of presentation transform parameters to the first audio signal presentation to form the acoustic environment simulation input signal;
applying an acoustic environment simulation to the acoustic environment simulation input signal to generate an acoustic environment simulation output signal;
applying the set of dialogue estimation parameters to the first audio signal presentation to form a dialogue presentation of the dialogue components; and
summing the dialogue presentation with the second audio signal presentation and the acoustic environment simulation output signal to form a dialogue enhanced audio signal presentation for reproduction on the second audio reproduction system;
wherein the second audio signal presentation is an anechoic binaural audio signal presentation.
