EDIT SAMPLE
FIND START/END
146
Pressing either of these pops up a window:
You should set a threshold level at which to find the start (or end) point.
The above example is probably not a good one but in the case of a drum
sound with a lot of 'dead space' such as the following, FIND START and
FIND END is very useful.
By setting an appropriate THRESHOLD, you can automatically set
START and END points to aid you with your editing.
