The document is a glossary created by a student named Callum Deighton for a unit on sound design and production. It contains definitions for over 20 key terms related to sound design methodology, file formats, limitations, recording systems, and sampling. For each term, Callum provides a short definition from an online source as well as any relevant details about how the term relates to his own production practice.

Software Plug-ins They are called that because these are
little computer applications that run
inside a "host" application, i.e., a
sequencer, typically. These plugin
devices are very important, as they have
led the software revolution towards our
virtual studios which is changing all
recording studios, both home and pro.
Today there are few hardware devices
left that cannot be emulated by plugins
and software. As you see from this
page, software based synthesizers,
effects processors, samplers and multi-
track recorders can all work together on
one single computer.
