Add Markers
Launch Sound Editor and add the audio tracks you would like to edit. Click anywhere inside the clips shown in the Clip Editor to place a selection line. Right-click on the selection line and select Add/Remove Marker. This adds a marker to your audio track. Of course, you can remove a marker in the same way.
Tips
A faster way to add markers to your clip is to place the selection line and then use the M key to add each marker.
You can also automatically detect tracks within your audio file to add markers to it. This is helpful if you have recorded audio that contains more than one music track. Select Track Detection from the Tools drop-down menu.
Click on Split Clip
After you have set markers in place, click on Split Clip. This opens the Split Clip window.
Select Current Position or Markers
The Split Clip window gives you the option to split the clip at your current position or at all markers. Choose which option you would like and the operation is completed.
Crop to Selection
If you are only interested in editing a small portion of the track, select that portion and choose Crop to Selection in the Edit menu. This crops the picture and deletes anything that is not selected.
Key Term
Crop To delete the unselected portion of a file.
Tip
Any time you have something selected, you can zoom to that selection by using the zoom tools in the upper right of your view or by right-clicking on the selection and choosing Zoom to selection. When you are done editing your particular selection, you can zoom back to your full view the same way.
Cut Unwanted Clips
Select the portion of track you would like to crop in the Clip Editor and click the Cut option in the taskbar.
Position Clips for Joining
Using the Mix Editor, position your clips in the order you would like them joined. They don't need to be right next to each other for the joining to work.
Select Multiple Tracks
After you have positioned your clips, select the tracks you would like to join by holding down the Control key and clicking on each one.
Click Join Clips
After you have selected the clips you would like to join, click Join Clips. This pulls the clips together and seams them as if there had never been a split.
