---

---
---Plays multiple copies of the sound with slight pitch and time variation. Used to make sounds sound "fuller" or "thicker".
---
---| "chorus"
---
---Decreases the dynamic range of the sound, making the loud and quiet parts closer in volume, producing a more uniform amplitude throughout time.
---
---| "compressor"
---
---Alters the sound by amplifying it until it clips, shearing off parts of the signal, leading to a compressed and distorted sound.
---
---| "distortion"
---
---Decaying feedback based effect, on the order of seconds. Also known as delay; causes the sound to repeat at regular intervals at a decreasing volume.
---
---| "echo"
---
---Adjust the frequency components of the sound using a 4-band (low-shelf, two band-pass and a high-shelf) equalizer.
---
---| "equalizer"
---
---Plays two copies of the sound; while varying the phase, or equivalently delaying one of them, by amounts on the order of milliseconds, resulting in phasing sounds.
---
---| "flanger"
---
---Decaying feedback based effect, on the order of milliseconds. Used to simulate the reflection off of the surroundings.
---
---| "reverb"
---
---An implementation of amplitude modulation; multiplies the source signal with a simple waveform, to produce either volume changes, or inharmonic overtones.
---
---| "ringmodulator"

---
---A sine wave. Follows a trigonometric sine function.
---
---| "sine"
---
---A square wave. Switches between high and low states (near-)instantaneously.
