The document discusses how sound effects manipulate the basic properties of sound, including propagation, amplitude, frequency, and timbre. It explains that propagation effects include delay, reverb, phaser, and flanger. Effects that manipulate amplitude include expanders, gates, compressors, and limiters. Frequency and timbre effects include various filters and equalizers. Understanding these basic properties helps simplify the multitude of sound effects.

1. Manipulating Sound
By Owen Richards
How various effects manipulate the basic
properties of sound

2. Simplifying the multitude of effects

There's a multitude of effects

Understanding the basic properties of
sound simplifies this multitude.

3. The basic properties of sound

Propagation

Amplitude (dB)

Frequency (Khz)

Timbre

4. Propagation

Sound moving through a medium

Moving through air: 1km/3 seconds

Space, depth, location

Various effects:
− Delay
− Reverb
− Phaser
− Flanger

5. Amplitude (dB)

The width of the sound wave

Or, how much the air compresses and
rarefies

Multiple track levels, panning.

Effects
− Expanders
− Gates
− Compressors
− Limiters

6. Frequency and Timbre

How fast sound is vibrating

Sine wave and timbre

Effects (manipulating timbre):
− Various filters
− Equalizer
