Audio examples

A Resonator is one of the many underrated and esoteric effects that can sound fantastic. Once you use it - you will want use it over and over again. It is a very musical sounding natural effect which can be used with any audio signal source.
A resonator effect duplicates and modifies your audio signal, which can have a nice stereo effect. It is used quite frequently in electronic music to create "that sound". And now you can make it too!
If you use it with acoustic instruments like guitars, pianos, or strings, you will understand why this effect is what you need for your productions. 

The REASONATOR Rack Extension is a utility to create a perfect acoustic resonance emulation. Reasonator is a Classical Resonator effect with Decay controls, but with the addition of high frequency controls, LFO and Curve modulations. Device also include stereo width, pre and post Multi-mode filters. The structure of Reasonator allows for morphing between two resonators that have their own individual settings. Morphing between these two resonators helps to create new and interesting audio experiments.

Product details

All physical objects resonate. Some have simple uniform resonance while others have complex resonance. When you play any acoustic instrument, you get a natural Acoustic Resonance effect. This sound is what you finally hear from your instrument when any sound source at its fundamental frequency is triggered. Acoustical instruments can have multiple harmonics. Higher harmonics correspond to integer multiples of the fundamental frequency. Acoustic resonance effects are a type of phase shift, but is better known as a Comb Filter with a wide range. A Resonator is more of a special effect with its own character than the classical Comb Filter. Some resonators may generate sound by exciting adjacent air particles in the surrounding medium.
The term "Acoustic Resonance" is sometimes used to refer to mechanical resonance in the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, acoustic resonance can occur at frequencies outside the range of human hearing.
When a string is vibrating in air, the resulting sound waves in the air have frequency patterns related to the frequency patterns of the vibrating string. The guitar string collides with the surrounding air molecules and generates longitudinal pressure waves in that medium.
Acoustic resonance is important for instrument builders and also for hearing.
Resonators help to create additional accents to any type of signal source by using a resonance decay effect. This can add some resonance and reverb of new modulated frequencies created from the fundamental frequency. Resonators interact with human ears and with the environment. Resonators isolate and emphasise matching frequency components of incoming signals. For example, any room with walls and air can be a Resonator. 
 A Resonator is one of the many underrated and esoteric effects that can sound fantastic. Once you use it - you will want use it over and over again. It is a very musical-sounding, natural effect with any audio signal source. It is perfect for electronic and acoustic instruments, such as guitars, organ tubes, and strings.
