The Core Audio Glossary defines audio-related terms used in the iOS and OS X Reference Libraries. Some definitions vary by technology, in which case more than one definition is provided.

Some of these terms are specific to Core Audio, while others are commonly used in the audio community. Additional knowledge of audio concepts (such as harmonic analysis or psychoacoustics) may be needed to fully understand some of the terms.

You can refer to this document to better understand terminology used in Core Audio or other audio-related documentation.
