If you want to chop huge WAV files up into smaller pieces (for instance, you might have recorded an entire album side and want to break it up into individual songs), you don’t need 3rd-party software — the built-in SoundRecorder app does a great job of this.

1. Drag the Wav file into SoundRecorder. Wait for a bit as it loads if the file is really big. You’ll know it’s completely loaded when the waveform display is showing.
2. Drag the semi-circular grippers at either end of the track indicator back and forth to mark the beginning and end of the sample you want to crop.
3. Right-drag or Ctrl-drag the waveform display to the Desktop or the Tracker and choose an output format from the context menu.
