Adding Audio Effects to the Signal Path

Connections

• more info
• .connect() connects two nodes together, usually something that makes sound to something that manipulates it
  • ex: sampler -> distortion
• Connections are directional, order matters
  • ex: source.connect(effect) can be thought of as source -> effect

Connect effect

• Build our chosen audio effect, assign it to a variable, and connect its output to the speakers (using the .toDestination( ) method)
• the effect needs to get created first before you can send a sound through it

var effect = new Tone.FeedbackDelay().toDestination();

• Build our sound source, assign it to a variable, and connect its output to our audio effect (using a new method called .connect( )

var multiplayer = new Tone.Players({...}).connect(effect);

Changing effects parameters for signals

example: FeedBack Delay Docs

• signals have the (~) by them in the docs
• allows audio rate (44,100 Hz)control over attribute
  • See for more info about sampling rates

see signal wiki

Reverb

• the persistance of a sound that continues after the original sound has ceased
• many echos bouncing off the walls, think the sound clapping in a cathedral or cave
• all spaces produce reverb
• Tone’s two types:
  • JCReverb - a simple Schroeder Reverberator tuned by John Chowning in 1970 - cheap but artificial sounding
  • Reverb - convolution, more expensive than the JCReverb but more natural

Let’s build a serial effects chain - pick three effects;

How do we build this?
