Opts --> Prefs has a count in control function. Turn it off.

Many of us use the free Audacity editor to load a sound file (.wav) and use it's features to trim the front and back end, and do fade in / fade out functions, plus a bunch of other things like making the track louder, add some reverb etc.

Lots of ways to 'skin a cat'.
