Using signal processing in real-time trumpet performance
Thomas J. Plsek, Daniel Brantigan · The Journal of the Acoustical Society of America · 2001
The real time use of signal processing for trumpet instrument performance provides an opportunity, as well as challenges, to create a type of hyper-instrument quite unlike most conceptions of the term. These include the expansion of the available sound palette, the problem of real-time parameter control, microphone techniques, and repertoire considerations. The various types of processing used includes reverb, pitch change, delays—short time and longer looping types, distortions, and combinations of the above. Normally, the processed signal is layered onto the acoustical output of the instrument, but by using such devices as the Yamaha Silent Brass one can diminish the presence of the acoustical signal of the instrument in the final output. By creatively managing the acoustic instrument and the electronic equipment, a vast array of musical resources become available to the performer enabling him/her to enhance existing performance environments, as well as find and develop new ones.
