reverb Flashcards
list 3 reverb parameters and explain what they are
Reverb type – What kind of reverb emulation it is. There are Halls, Rooms, Chambers, Plates, etc.
Size – What the physical size of the space is. This can range from small through to large.
Diffusion – How far apart are the reflections from each other.
Pre-delay – Sets a time delay between the direct signal and the start of the reverb
Decay time -Also known as RT60, which is how long it takes for the signal to reduce in amplitude 60 decibels.
Mix (Wet/Dry) – Sets the balance between the dry signal and the effect signal. When you have the reverb effect on an insert you need to adjust the wet and dry ratio, when you are sharing the reverb in a send and return configuration you want the mix to be 100% wet.
Early Reflection level – Controls the level of the first reflection you hear. Early reflections help determine the dimensions of the room.
what type of recordings would you use reverb on?
close-mic techniques or recordings made in dry spaces
how can you record natural reverb?
capturing ambient mic’ing techniques
more reverb is captured if a mic is further away
what are the best polar patterns for recording reverb?
omnidirectional or figure of 8
up until the 1950’s reverb was made by playing a dry signal in a room, how exactly would they do this?
This was achieved by placing a loudspeaker at one end of a room and an omni-directional microphone at the other. The height and angle of the microphones affect the amount of reverb. The room would be constructed from reflective material like stone or concrete to increase the amount of reverb. The room needs to be sound-proof to prevent noise from getting in. The signal from this microphone would then be added to the dry mix. Often this reverb is controlled in the mix with a keyed gate . Some studios used garages or stairwells
how does plate reverb work?
theres a mic suspended one end and a speaker the other, in between are two plates, the sound is played through the speaker and reverberates off of the plates and is recorded onto the mic at the other end
what is a limitation of plate reverb?
very expensive
what sort of sound did plate reverb produce?
very dense reverb
what reverb was developed in the 1950’s and how did it work?
spring reverb, similar fashion to plate but a spring is used instead of a metal sheet
what is an advantage of spring reverb?
it’s a lot smaller
what sort of sound does spring reverb produce?
thundering, twangy sound
when did digital reverb start to appear?
1980’s
who were the pioneer manufacturers of digital reverb?
yamaha and lexicon
what is the main advantage of digital reverb?
the character of reverb can be easily changed by adjusting parameters on-screen, or even via MIDI
