Abstract
A method of processing audio data for replay on a mobile device with a first speaker and a second speaker, wherein the audio data comprises a respective audio signal for each of the first and second speakers, includes: determining a device orientation of the mobile device; if the determined device orientation is vertical orientation, applying a first processing mode to the audio signals for the first and second speakers; and if the determined device orientation is horizontal orientation, applying a second processing mode to the audio signals for the first and second speakers. Applying the first processing mode involves: determining respective mono audio signals in at least two frequency bands based on the audio signals for the first and second speakers; in a first one of the at least two frequency bands, routing a larger portion of the respective mono audio signal to one of the first and second speakers; and in a second one of the at least two frequency bands, routing a larger portion of the respective mono audio signal to the other one of the first and second speakers. Applying the second processing mode involves applying cross-talk cancellation to the audio signals for the first and second speakers.
