This glossary includes terms used throughout the book and those you will likely encounter when working with the various kinds of music technology employed for the lessons, activities, and projects described. I have tried to keep the definitions and explanations straightforward, using as little technical jargon as possible.
AIFF Audio Interchange File Format: Format for storing sampled sound developed by Apple and used on Macintosh computers. AIFF is uncompressed audio; fidelity is high. File size is large, about 10 MB (megabyte) for every minute of recorded audio. These files have the extension. aif or. aiff.
Amplitude The strength of a (sound) signal.

Blog Short for web log: Basically, an online journal that allows users to make posts incorporating text, images, audio, video, web links, and more.

Subscribers to the blog are notified when new posts are added and can comment on them.
Break point With audio recording software, a point of articulation entered along a track’s automation line. Each breakpoint allows for an automated change of direction in volume, pan position, or some other parameter during playback.
