Abstract

This paper presents a detailed description of the development of a real-time spring reverb effect interface which is built based on the solution of a complex physical modelling implementation of helical springs. Impulse responses for various helical springs with different physical parameters are computed offline using an implicit finite difference scheme. These are then used to manipulate a real-time input sound by means of a partitioned convolution implementation, which allows for the use of long impulse responses with low latency. Furthermore, a smooth transition is carried out when changing from one impulse response to another, thus providing the means for real-time manipulation of the physical parameters of the spring and consequently the effect’s quality.
