Silence Finder

There used to be an effect called ‘silence finder’, which I found very useful on audiobook recordings. Please can this be restored? If not, is there another way to find silences other than manually searching a file?

“Silence Finder” and “Sound Finder” have been replaced with a new “Label Sounds” effect: Label Sounds - Audacity Manual

The new effect is more accurate, and more versatile, but may be more than you need. If you would prefer to use the old “Silence Finder” effect, you can get it here: Missing features - Audacity Support
Installation instructions for “Nyquist plug-ins” on Windows can be found here:
