Silence Finder and Sound Finder
- Peter 15May13: Done - I added an examples section.
- Gale 09Jul13: Should the examples now be inside the new example div?
- Peter 9Jul13: For consistency I would have thought so. I don't think Connie has stated a view on this yet ...
- Peter 9Jul13: In fact Connie does not even list or mention the example div in Spans and divs
- Gale 09Jul13: Perhaps we need to look at more places where we should add this div to decide what the rules are. I think there should not be an H2 inside the div as here. It should be like Splitting_and_Joining_Stereo_Tracks#examples. Does my change to H3 look better or not?
- Peter 11Jul13: looks fine with the H3s to me.
- Peter 9Jul13: For consistency I would have thought so. I don't think Connie has stated a view on this yet ...

Silence Finder...
- Accessed by:
Silence Finder divides a track up 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 tracks, increase the silence level and duration. If some tracks don't 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...
- Accessed by:
Sound Finder divides a track up 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 tracks have more than one label, increase the silence level and duration. If any labels extend into other tracks, reduce the silence level and duration.
Examples
Here is a stereo track with six songs. The entire project is selected prior to using the Analyze functions.
Example with Silence Finder
After running we 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 run on 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.
