Generating audio-responsive video images in real-time for a live symphony performance
MetadataShow full item record
Multimedia performances, uniting music and interactive images, are a unique form of entertainment that has been explored by artists for centuries. This audio-visual combination has evolved from rudimentary devices generating visuals for single instruments to cutting-edge video image productions for musical groups of all sizes. Throughout this evolution, a common goal has been to create real-time, audio-responsive visuals that accentuate the sound and enhance the performance. This paper explains the creation of a project that produces real-time, audioresponsive and artist interactive visuals to accompany a live musical performance by a symphony orchestra. On April 23, 2006, this project was performed live with the Brazos Valley Symphony Orchestra. The artist, onstage during the performance, controlled the visual presentation through a user interactive, custom computer program. Using the power of current visualization technology, this digital program was written to manipulate and synchronize images to a musical work. This program uses pre-processed video footage chosen to reflect the energy of the music. The integration of the video imagery into the program became a reiterative testing process that allowed for important adjustments throughout the visual creation process. Other artists are encouraged to use this as a guideline for creating their own audio-visual projects exploring the union of visuals and music.
