Programming Sound with Pure Data

Appendix 1Glossary

Amplitude

The amount of energy in an audio signal.

Bit Depth

The number of bits available per sample to store signal data.

Chorusing

An effect added to a sound by combining it with a delayed copy with a longer duration than flanging. It adds an interesting “doubling” effect and, if modulated, can give the impression of motion.

Flanging

An effect added to a sound by combining it with a slightly delayed copy. It adds an interesting “whooshing” effect caused by interference in different frequencies in the sound.

Frequency

The speed of an audio signal, which determines the pitch of a sound.

Frequency-modulation synthesis

A synthesis method where a modulator operator’s frequency changes the frequency of a carrier operator.
