Abstract
Aspects of the invention provide methods, computer-readable media, and apparatuses for spatially manipulating sound that is played back to a listener over a set of output transducers, e.g., headphones. The listener can direct spatial attention to focus on a portion of an audio scene, analogous to a magnifying glass being used to pick out details in a picture. An input multi-channel audio signal that is generated by audio sources is obtained, and directional information is determined for each of the audio sources. The user provides a desired direction of spatial attention so that audio processing can focus on the desired direction and render a corresponding multi-channel audio signal to the user. A region of an audio scene is expanded around the desired direction while the audio scene is compressed in another portion of the audio scene.
