Preface
Acknowledgments
1 Introducing the Web Audio API
	The Web Audio API
	The audio context
	What you need to get started
		Example: Hello World
		Example: – adding user interaction
Interlude – Generating sound with scheduled sources
	2 Oscillators
		A bit of theory
		OscillatorNode
			Parameters
			The oscillator types
			Example: basic use of the OscillatorNode
		The PeriodicWave
		Square wave example
		Pulse wave example
		The detune parameter
			Example: detuning an oscillator
		Note
	3 Audio buffer sources
		The AudioBuffer
			Example: creating a buffer source
		The AudioBufferSourceNode
			How does playback work?
			Example: varying playback of an audio buffer
			Example: wavetable synthesis with audio buffers
			Example: pausing audio
			Example: playing audio backwards
	4 The constant source node
		Introducing the constant source
			Example: DC offset with a ConstantSourceNode
			Example: using a ConstantSourceNode to affect many parameters
			Example: grouping audio
Interlude – Audio parameters
	5 Scheduling and setting parameters
		Audio parameters
		Changing audio parameters
			Methods
				setValueAtTime(value, startTime)
				linearRampToValueAtTime(value, endTime)
				exponentialRampToValueAtTime(value, endTime)
				setTargetAtTime(target, startTime, timeConstant)
				setValueCurveAtTime(values, startTime, duration)
				cancelScheduledValues(cancelTime)
				cancelAndHoldAtTime(cancelTime)
			Computation of value
			Example: beep sound with parameter automation
			Example: beep sound with custom automation
			Example: repeating a beep
			Example: crossfade
			Example: synthesising a bell sound
	6 Connecting audio parameters and modulation
		Connections revisited
		Disconnecting nodes
		Connecting audio parameters
			Example: FM synthesis
			Example: AM synthesis
		Tremolo and vibrato
		Ring modulation
Interlude – Destination and source nodes
	7 Analysis and visualization
		AnalyserNode
			FFT windowing and smoothing over time
			Using the AnalyserNode
			Example: visualizing sound
	8 Loading, playing and recording
		Working with media elements
			Example: use of an
