Room Size: simulated spacePredelay: How much time before first reflectionReverberance: Length of tailDamping: high frequencies decay more quicklyTone Low: reduce low freqTone high: reduce high freqWet gain: increase volume of reverbDry gain: increase volume of signalStereo width: channel separationWet only: remove original signal

Reverb Settings

1. Duplicate a sound file (Ctr/Cmd A, Ctrl/Cmd C + tracks > add new > mono track, Ctrl/Cmd V)

2. Reverse Track 2 (Effects > Reverse)3. Apply reverb Effects > Reverberation > Manage> Factory

Delay Type: regular, bouncing ball (reduces time as repeats), reverse bouncing ball (increases time as repeats)Delay Level Per Echo: Amount of change in amplitude in each delayDelay Time: time between repeatsPitch Change Effect: delay will change frequency/tempoLQ Pitch Shift: Changes frequency while maintaining timePitch change per echo: in semitones

Number of Echoes: how many times repeatsAllow duration to change: ***need room in file for delay

Chorus: Multiple delays with deviations to create effect of chorus singing

Automatic Double Tracking: ADT: automated chorus-style effect

Phaser (Phase Shifter)

Uses constructive and destructive interference ”swept” by LFO

Stages: more = stronger effectDry/Wet: 0 = unprocessed, 255 = only delay. Most = 128LFO Freq: adjusts sweep rateLFO start: starts in cycleDepth: How high sweep isFeedback: feeds signal back into phaserGain: increase output amplitude
