For our studio, I went ahead and purchased several Spring reverb tanks of different sizes. A good place that explains about them and sells them is Amplified Parts. I have two medium, one long and one short reverb tank. Doing so allow me to mix and match and tailor the reverb I want to generate….
Pre-delay, delays the entrance of the reverb. So if, for example, pre-delay is set to 0 milliseconds, then the reverb begins exactly when this sound does. This could end up muddying up the mix. The longer the Pre-delay is, the more space between the entrance of the sound and the entrance of the reverb and that space will clean it up considerably.
Decay parameter represents how long it takes the reverb to fade to where you can no longer hear it. For example, if Decay is set on 4s then it takes 4s until the reverb tail falls below a level that we could hear it. The longer the decay time is, the more it pushes a track further…
Why we use reverb? To fit a track in a specific physical acoustic space. Change or highlight the sound texture. Make the track larger or wider than it really is. Artificial stereo space. Position the track in the mix. The more the reverb the farther away in the mix is the instrument. .
