A complex panning method for near-field imaging
A complex panning method for near-field imaging
Conventional amplitude panning can be used to produce images of distant objects. An extended panning method is presented that can also produce image cues for the near-field region, by the control of Inter-aural Level Difference cues in the low frequency range below ~1000Hz. The approach has grown from an adaptive panning method that corrects for the dependence of image direction on head orientation. Stereo panning functions are derived from a general formulation. A single first order filter is required for each image. The method is tested by simulating a range of configurations using measured Head Related Transfer Functions, and also with listening tests. The results confirm the ability of the method to control near-field cues, while also compensating image direction for head rotation.

Abstract
Conventional amplitude panning can be used to produce images of distant objects. An extended panning method is presented that can also produce image cues for the near-field region, by the control of Inter-aural Level Difference cues in the low frequency range below ~1000Hz. The approach has grown from an adaptive panning method that corrects for the dependence of image direction on head orientation. Stereo panning functions are derived from a general formulation. A single first order filter is required for each image. The method is tested by simulating a range of configurations using measured Head Related Transfer Functions, and also with listening tests. The results confirm the ability of the method to control near-field cues, while also compensating image direction for head rotation.
