METHOD AND DEVICES FOR VISUALIZATION OF MULTICHANNEL SIGNALS AND FOR CONTROLLING THE SPATIAL AUDIO IMAGE

摘要

A method for visualization of multi-channel audio signals, a method for converting audio information by using a spatial cue, and an apparatus thereof are provided to visualize reproducing processes of the multi-channel signals and apply variation of the spatial cue to generation of the multi-channel signals, thereby reproducing realistic multi-channel audio signals and adjusting a position of a visual audio source of an audio signal. An apparatus for visualization of multi-channel audio signals, and converting audio information by using a spatial cue comprises the following parts: a SAC(Spatial Audio Coding) which is constituted with a SI decoder(102) for decoding the spatial cue and SAC decoder(101) for synthesizing multi-channel signals; a spatializer(103) and a visualizer(104) for receiving the decoded spatial cue information; and a displayer(105) for receiving a panning angle and power gain information of each channel.
