What is a chorus effect?
Hear a chorus effect in a live lab and learn how rate, depth and mix set its pitch drift, how chorus differs from vibrato, and how to keep it safe in mono.
What is a flanger?
A flanger mixes a sound with a copy delayed by under 10 ms and sweeps it. Hear the comb, feedback and the jet sound in a live lab, with settings for drums and guitar.
What is a phaser?
Hear a phaser sweep in a live lab and see how chained allpass filters cut a few wide notches, what stages, rate, depth and feedback do, and how to use one.
What is tremolo?
Hear tremolo in a live lab: set rate, depth and LFO shape, sync the pulse to your tempo, turn it into auto-pan, and learn how it differs from vibrato.
What is vibrato?
What vibrato is, how a vibrato effect bends pitch with a moving delay, and how rate and depth set the swing in cents, with a playable lab and an ear quiz.
What is auto-pan?
Auto-pan moves a sound between the speakers with an LFO. Hear it built from two tremolos, set rate, depth and shape, and see what pan law does to it in mono.
What is ring modulation?
Ring modulation multiplies a sound by a carrier, turning each frequency into a sum and a difference. Hear why it sounds metallic, how it differs from AM, and more.
What is frequency shifting?
A frequency shifter moves every frequency by the same number of hertz. Hear why that sounds metallic, how it differs from pitch shifting, and try it live.
What is a rotary speaker?
Hear how a Leslie rotary speaker bends pitch, level and stereo with a spinning horn and drum, then set the speeds, ramp, balance and mics in a live lab.
What is an LFO?
An LFO is a slow wave that moves a setting for you: tremolo, vibrato, filter wobbles and auto-pan. Hear every shape, rate and destination in a live lab.
Tremolo vs vibrato
Tremolo moves the volume, vibrato moves the pitch. Hear both on one sound, see the numbers, and learn which to use, how to set them and why the names get swapped.
Ring modulation vs frequency shifting
Ring modulation gives two copies of every frequency and frequency shifting gives one. Hear both on the same sound, with worked numbers and when to use each.
Chorus vs flanger vs phaser
Hear chorus, flanger and phaser side by side in a live lab, see how each one sweeps notches through a sound, and learn which suits a guitar part or a vocal.
