# Class Sound

A sound annotation (PDF 1.2) shall analogous to a text annotation except that instead of a text note, it contains sound recorded from the computer’s microphone or imported from a file.

The annotation shall behave like a text annotation in most ways, with a different icon (by default, a speaker) to indicate that it represents a sound.
