APT Quiz 4 - Reverb

Direct Sound

The original impulse of sound in an environment.

Early Reflections

The first echoes that bounce back in a space, indicating the size of the space.

Reverb

The series of diminishing late reflections in a space.

Acoustic chamber

Signal is fed to a speaker in a space and microphones capture the resulting sound

Spring reverb

Often found in guitar amps

Plate reverb

Large sheet of metal is vibrated

Algorithmic reverb

Computer code based on hypothetical rooms or types

Convolution reverb

Utilizes the impulse response of a room derived from a single sound to generate a pattern of reverb

Select ALL benefits of using a parallel (send/return) procedure for adding reverb:

- reduced CPU power required over applying as Insert

- allows blending of multiple sources into a single reverb

- easier to edit parameters applied to multiple instruments

When using a parallel process you should always leave the processor's Wet / Dry Blend control at 100% and adjust the blend using the send / return.

True

The send level should always be at unity and the return should be set to the desired reverb level.

False

Algorithm

Chooses the reverb type (i.e. the hypothetical space it is trying to emulate)

Decay

Reverb Time, RT60

Pre Delay

The gap between the direct sound and the onset of reverb

Diffusion

Adjusts the density of the reverb

Wet / Dry Blend

Adjusts the balance of the unprocessed and processed signal

LPF

Rolls of the high frequencies

HF Cut

Chooses how fast the high frequencies decay
