Dual Spring Reverb is an effect plugin that uses a physical model of helical spring vibration to recreate the classic sound of spring reverbs.
Innovative and creative spring reverb
Dual Spring Reverb is the first ever plugin to model wave propagation in helical springs. The audio engine is built entirely upon the simulation of the inherent physical equations. This gives creative control of the setup of the springs, allowing you to design your own unique sound. Dual Spring Reverb will sit perfectly on your guitar, synth, or drum tracks, adding dripping tones with a colourful spectrum.
Dual Spring Reverb是有史以来第一个模拟螺旋弹簧中波浪传播的插件。音频引擎完全建立在对固有物理方程的模拟之上。这样就可以创造性地控制弹簧的设置，让你设计出自己独特的声音。Dual Spring Reverb将完美地放置在您的吉他、合成器或鼓轨道上，添加色彩丰富的滴落音调。
Customisable spring setup
Dual Spring Reverb has two separate springs which can be configured independently. Both springs have controls for the echo time and chirp cutoff frequency, and you can set the chirps to spread out over time. In addition there are global controls for the level of ‘boing’, the damping and tone, as well as a 7-band mode equalizer. Stereo output is taken from the ends of each spring and these are mixed together via a cross-fade. Altogether this allows for a huge range of spring tones that can be tailored to your individual material.
Pure physical modelling
The plugin uses a purely mathematical model of spring vibration to create sound. Our modelling starts from a description of wave propagation in elastic helical structures. The physical properties such as length, wire radius, and pitch angle are then mapped to the perceptual parameters as detailed above. From there we create a discrete modal system which is updated over time. Further background details can be found in this technical paper.
