Visual Enhancement Using Multiple Audio Streams in Live Music Performance

The use of multiple audio streams from digital mixing consoles is presented for application to real-time enhancement of synchronised visual effects in live music performances. The audio streams are processed simultaneously and their temporal and spectral characteristics can be used to control the intensity, duration and colour of the lights. The efficiency of the approach is tested on rock and jazz pieces. The result of the analysis is illustrated by a visual OpenGL 3-D animation illustrating the synchronous audio-visual events occurring in the musical piece.
