In order to achieve an enhanced audio experience, audio information, for example a movie soundtrack having binaural components, may be stored on a mobile device prior to the beginning of a movie presentation in a theater. Responsive to an audio sync signal presented to the mobile device, the audio information may be played back from the mobile device in a manner synchronized to display of the movie on a theater screen. The audio sync signal may be a high-frequency signal emitted by a loudspeaker in the theater. The audio information may be customized for a user. For example, via use of a binaural audio system, a user of a first mobile device may experience a movie presentation in a theater in a first language, and user of a second mobile device may experience the same movie presentation in the theater in a second language.
