3. Spatial arrangement
Professional engineers use reverberation not only to give the volume to a sound, but also to move it off or nearer to a listener. A clumsy example of it is the use of some sort of scaling preset like “cave”. The long fading tail of the reverberation creates an illusion of the distance of the sound processed by this reverberation.
It goes without saying that such processing can significantly mud a mix as it takes a good deal of space at mixing services. That’s why it should be used only in key points and in limited quantity.
Thanks to the reverberation effect you can move the sound away and closer with the help of attenuation of high frequency and pre-delay time settings.
When high frequency attenuation happens fast, the sound seems to be farther as the air absorbs high frequencies a lot faster than low and middle. If you don’t suppress high frequencies, sound source distance effect won’t happen, and it can be heard just as a special effect.
Pre-delay time is the time which lasts from the burst of a clean sound to the beginning of the similar burst processed by a reverberator. Otherwise speaking, it is one of the factors which on mixing build up the distance to the imaginary surface reflecting the sound.
Consequently, when pre-delay time lasts long, the processed sound seems to be in a volume space but at the same time closer to a listener. When the pre-delay time is little or zero, the sound seems to be far in a volume space.
4. Processed reverberation
All the manipulations with the sound processed by reverberation belong to great deal of tricks of this kind.
One of the most remarkable effects is reversed reverberation. To get it, it is necessary to reverse the original sound, to process it with the reverberation picked up beforehand and reverse it backwards. After such processing the reverb tail won’t fade away after the burst of a sound, but, on the contrary, it will keep rising before it.
Other techniques include reverberated signal processed by different effects. For instance, you can connect a phaser or an octaver to the insert of the send processing channel. Therefore, professionals get a clear original sound and the reverb tail processed by special effects afterwards.
On the whole, there are a vast number of techniques for use of reverberation. Only 4 methods of them have been listed out in this article. I advise you to keep experimenting with reverberation constantly to find permanently new and new kinds which you can get as a result of effect processing.
