Recognise what the analyser detects
Audacity Label Sounds identifies passages using level and duration controls, then writes point or region labels. It does not understand whether a pause is a new topic, a hesitant speaker or the end of a song. A labelled sound region is therefore a useful navigation proposal, not verified chapter information. First choose whether the goal is to mark positions or surround complete items for later handling.
Review a varied section first
For an original example, an authorised interview contains a long answer with several pauses followed by a brief station identification. Run the analyser on a representative section and listen across the proposed divisions. Increase the minimum silence duration if natural pauses inside one answer are being mistaken for boundaries. Check the minimum label interval separately, since it deals with labels which occur too close together after detection. Include quiet beginnings and endings in the listening review.
Give the resulting markers useful names
The current manual distinguishes point labels for navigation from regions around sounds for handling complete pieces. After correcting boundaries, replace mechanical counter names with useful descriptions where appropriate. Inspect the actual exported items if the installed version offers the intended split export workflow; labels alone are not a collection of new audio files. Keep the continuous source and review the transitions between items, especially if background clicks or applause could have influenced the detected level.
