EFFECTS AND PLUG-INS IN AN OVERVIEW 199
Produces a typical "floating/shimmering sound" by modulated detuning of a signal to
"thicken up" its sound or spread it across the stereo field. Detuning is achieved via a short
delay, the length of which can be varied by the modulation. This produces the so-called
"Doppler" effect.
Parameters
-Time: Delay time in milliseconds. This may be understood as the "base" modulation that is
stretched or compressed by the modulator.
- Rate: Modulation speed
- Depth: Modulation amplitude. Low values modulate only a little; higher values create a
clear vibrato.
 Flanger
Algorithmically similar to chorus, but different in that the delay time is significantly lower and
delay works with repetitions (feedback). A flanger sounds more "cutting" and up-front than
a chorus.
Parameters
- Rate: Modulation speed
- Feedback: Delay feedback
- Depth: Modulation of amplitude
 Phaser
A modulation effect just like chorus & flanger, but in this case no detuning takes place.
Filter components periodically alter the signal's "phase response" (principle of the "phase
shifter"). Characteristic notches are produced in the frequency spectrum response to
create so-called "comb filter effects". The phaser effect is suitable for pads and
"psychedelic" sounds.
Parameters
- Rate: Modulation speed
- Feedback: Feedback of filter steps
- Depth: Modulation amplitude
 Room reverb/hall reverb
In the case of reverb, there are two realistic simulations of natural reverberation. Sounds
receive "atmosphere" to appear lively and "authentic". Room reverb simulates a small
space with high echo density. Hall reverb mimics the typical reverb of large concert halls.
Since natural spaces never sound "static" (air molecules are constantly moving and the
reflection process is quite complex), both algorithms include a modulation parameter which
varies the delay time of individual echoes and thereby affects the liveliness of the reverb
impression depending on strength.
