Analyze Menu
The Analyze menu is intended for effects and plug-in effects that
do not modify the audio, but simply open a dialog with some
descriptive information. Audacity also supports Analyze commands that
create annotations in a Label Track.
Audacity does not come with any built-in Analyze commands, so
anything in this menu must be a plug-in. It is possible for a
poorly written plug-in to crash Audacity, so always save your work
before using a plug-in.
