Learning outcomes

At the end of this week you will be able to:

• explain what a sound synthesizer does
• understand the terms ‘sound synthesis graph’ and ‘unit generator’
• implement basic synthesis graphs using web audio API
• work with amplitude, pitch and timbre
• respond to user input

The key techniques we will cover are as follows:

• Wiring an oscillator to the audio output
• Setting oscillator parameters from code
• Using oscillators to modulate other oscillators
• Shaping amplitude using a triggerable envelope
• Taking user input from the keyboard and mouse
