Analyzers
Analyzers
Plug-ins that measure or describe the selected audio without changing it.
An analyzer reads the selection and tells you something about it. Nothing is written back to the audio: the result arrives either as a message on screen or as a set of labels in a new label track, which you can then use to navigate or to drive further edits.
Where to find them
The Analyze menu.
Notes
Analyzers need a selection to work on, and they only look at the audio inside it. Selecting the whole of a track before running one is the usual starting point.
Because nothing is altered, an analyzer is safe to run at any time, and running one is not something you need to undo — though analyzers that add labels do create a label track, and that addition can be undone.
- Label Sounds Find the sounds in a recording, separated by silences, and label each one.
- Beat Finder Place a label on every beat it detects in the selected audio.
- Measure RMS Report the average level of the selection in dB.
- Find Clipping Not available in Audacity 4.
- Contrast Analyzer Compare the level of speech against the level of background sound, for accessibility checking.
