Silence Finder divides up a selection by placing point labels inside areas of silence. Use this if you just want to split the recording into tracks at a specific point without removing the silences between them.
If labels are produced in the middle of album tracks, increase the silence level and duration. If some album tracks do not have a label between them, reduce the silence level and duration. See Setting Parameters for more help choosing values to place the labels correctly.

Sound Finder divides up a selection by placing region labels for areas of sound that are separated by silence. Use this to make the labels show the exact region of each track to be exported. This lets you remove some or all of the silence between the tracks.
If any album tracks have more than one label, increase the silence level and duration. If any labels extend into other album tracks, reduce the silence level and duration.

Here is a stereo track with six songs. The entire project is selected prior to using the Analyze functions.
Example with Silence Finder
After runningwe can see that Audacity has identified the six songs, placing an "S" label just before the beginning of each song plus a seventh label at the end (as the final track ends in silence).
Example with Sound Finder
If instead we runon the same selected audio we can see that Audacity has again identified the six songs giving them numerical labels. The labels exclude a small amount of the gaps between the songs (seen most clearly between labels 5 and 6) so the lead-in and lead-out for each song would be shorter.
