AB  - The unique sonic quality of spring reverberation, and its historical importance in many musical genres, motivated implementing this sound with modern digital signal processing techniques. Spring reverberation produces chirplike responses. Rather than attempt to reproduce the physical vibrations of springs, this research uses a parametric model to duplicate their sound. The basic model consists of a spectral delay filter placed into a feedback loop with a long delay line and a selectable loop gain. A delay line is modulated with a strongly correlated random-number sequence. Parameters such as delay time, chirp shape, and decay rate can be adjusted.
