User interface for multi-channel sound panner

摘要

A method and apparatus for multi-channel panning is provided. Multi-channel panning allows the operator to view how a manipulated source signal will be heard by a listener at a reference point in a sound space. The panner user interface (UI) displays a separate visual element for each channel of source audio, thus the operator can see how each channel will be heard by a listener at a reference point in the sound space. Each visual element may depict the apparent point of origination of its corresponding source channel. Each visual element may depict the apparent width of origination of its corresponding source channel. Each visual element may depict the amplitude gain of its corresponding source channel. An operator can choose a mix of attenuating or collapsing behavior when panning. Moreover, the visual elements depict the relative proportions of attenuating and collapsing behavior.
