AUDIO DECODER CONFIGURED TO CONVERT AUDIO INPUT CHANNELS FOR HEADPHONE LISTENING

摘要

The proposed technology provides an audio decoder (100) configured to receive input signals representative of at least two audio input channels. The audio decoder is configured to provide direct signal paths and cross-feed signal paths (10) for the input signals. The audio decoder is configured to apply head shadowing filters (20) in the direct signal paths and cross-feed signal paths for simulating head shadowing of loudspeakers placed at different angles to an intended listener. The audio decoder is also configured to apply phase shift filters (30) in the direct signal paths and cross-feed signal paths for introducing a phase difference between the direct signal paths and the cross-feed signal paths representing a phase difference occurring between the ears of the intended listener. The audio decoder is further configured to sum (40) the direct and cross-feed signal paths to provide output signals.
