Many expert has researched reverberation effect processing in digital domain, and (in my opinion) can be classified on several mainstream methods. The pick-up then returns the signal to the amplifier or the processing circuits. Finally, a pickup coil picks the reverberated sound at the other end of the spring. Moreover, different springs arrangement with different characteristics would produce rich and unique resonant characteristics. In addition, the spring joints adds more complex reflections in the middle of its traveling path. Because of the different traveling speed of high and low frequency waves, the reflection produces more complex waves. During it’s travel, the amplitude is decreasing until deceasing.
The created vibration is then travels to the other end and bounce back and forth between two ends. The audio signal drives an input coil that vibrate the spring at one end. shows the basic construction of spring reverb tank.įigure 2. The first attempt to mimic a room reverberation without a real reverberation chamber is done by a spring reverb tank (see reference ). After that, he should place some loudspeakers at certain location and place a microphone at another location inside the chamber. In the old days, the only way to reproduce a reverberation effect is by using a real reverberation chamber.įor good effect, someone should build a large room with complex geometry with carefully selected wall material. The natural process shown in the Figure 1 is the illustration of reverberation. As the sound bounces back and forth in three dimensional space, the reflections creates more and more complex pattern. Real reverberation happens in a performance chamber when the walls and every object inside reflects the sound back and forth. Reverberation In Real Situation Introduction to Reverberationīefore getting into the design of DIY reverb pedal circuit, lets see the concept of reverberation first.
