Basic practical approach for understanding reverberation :
Think of a rectangle room, you as listener in the middle (horizontal). Now place the instruments in front of you.
Think of the dry amount and the wet reverbed signal separately. For now, only take care about the rear wall as the reverb reflection. In this basic reverb model the following will happen:
A ) near instruments
- dry signal comes without delay and most less eq-ed (talking about only negative/subtractive eq-ing).
- The wet amount comes much delayed in milliseconds, because the sound has to travel to the rear wall and the again back to your ears.
- The reverb tail is much more dull, because higher frequencies loose quicker energy than lower frequencies while traveling thru air.
- The tail basically is smaller eq-ed than the dry signal. Also the wet amount is much quieter than the dry signal.
- The dry signal will arrive mostly punctual, non-wide. Thru absorption the reverb tail isn't that long.
B ) distant instruments
- dry signal comes about half time delayed of the drys wet signal. It is about the
same half eq-diff (distant dry vs. near dry) like near's dry-wet difference, since all the way only one time to travel.
- The wet part comes in at almost the same time with the dry part.
- The reverb here is the brightest/original of all possible - in relation the the dry signal.
- The signals are very wide. And also more long, because less absorption.
- The dry signal is of course much quieter than the dry signal of the near instrument.
- To maximize the distant effect, you can also eq the wet signal a bit larger than the dry signal.
C ) By combining A and B, you now can place instruments in between
D ) Place the instruments in panning maybe like a band (meh). Low bass always middle ( you cannot hear panning below 100 Hz). The more distant the place, the less wide (but only slightly) can be the panning.
E ) Bass reflections are mostly annoying and should be filtered
F ) same rules for delay
G ) You can think about this also for the left and right wall. Basically I would recommend here a simply a delay with filters (multi tap device). It's the same, just rotated by 90 degree.
H ) Using multiple EQs is totally ok. This is digital.
I ) Advanced stuff: transients, ear space difference / haas
J ) Crazily advanced stuff: Rotate your head now
K ) Just use a modern reverb plugin and move "distance" slider
