Properties of Sound

Pitch - tonal or atonal
Loudness / Amplitude
Timbre - Character and quality of a sound outside of pitch/note and loudness

○ Time Domain - how does amplitude change in time ○ Frequency Domain - how does frequency content change in time

Perceived Duration
Envelope and Articulation
Spatial Location, Diffusion, Reverberant Environment

Synthesizer Building Blocks

Source - Oscillator, Noise
Modifier - Filter, Envelope
Controller automatic (programmed) or manual - LFO, Macro, Keyboard, Modwheel

Source Modifier Controller

SLIDE 5

Source - Waveforms

[Discrete] Fourier Transform - any signal can be represented as a summation of sine waves
Fundamental - Base Frequency (Note)
Harmonics - multiples of the fundamental frequency (1/n of the wavelength)

Oscillators Types ○ Sine - Fundamental only ○ Square - Odd Harmonics only

○ Sawtooth - All Harmonics ○ Hybrid

Types of Software Synthesizers

Main Types of Software Synthesizers

○ Subtractive - Massive, Sylenth1 ○ Additive - Razor ○ FM - FM8 http://en.wikipedia.org/wiki/Frequency_modulation_synthesis ○ Granular / Sampling - Ableton’s Granulator II, Sampler

Source Generation

○ Wavetable - Massive, Serum ○ Physical Modelling / Computational - Ableton Analog

Patch Design

Traditional Types of Patches

○ Lead ○ Pad ○ Synth ○ Bass ○ Bells ○ Drum - High Hat, Snare, Kick ○ Sequence ○ Pattern ○ Builds / Noise Sweep ○ Soundscape
