As more than one person has noted over the years, the Silence Finder analyzer has come and gone, moved, renamed, been replaced (“Label Sounds”), and now apparently moved to an external Vamp plugin. That plugin (Aubio) works fine, but it checks and labels silence in ALL tracks, which is a pain for us doing many-track recordings.
Back in 2021, Steve said ‘The old Silence Finder is still available as an optional “Nyquist plug-in”.’ But the link he provided now goes to the new Audacity Support page, and even following the difficult trail from there to Nyquist Analyzer plugins is a dead end. https://plugins.audacityteam.org/analyzers/analysis-plugins
I’m running Audacity 3.6.4 on Windows, and “Label Sounds” is not in the Analyze menu. Ah-ha, it was not enabled in the Plugin Manager list! I don’t think I did that… Is it possible it’s disabled by default?
