  2. 2Drag on the waveform to pick the part to keep. Nudge the end handles to the exact second, and click to preview.
  3. 3Choose MP3, M4A, or WAV and hit Cut. For a ringtone, turn on fade in/out for a smooth finish.

Great for

For example, it's perfect for cutting one line of a chorus from a favorite song into a phone ringtone.

It's also handy for keeping just the few minutes you need from a long recording, or trimming noise off the start and end.

Easy to eyeball with the waveform

Loud parts draw tall, quiet parts draw short, so you can see where everything is at a glance. Drag roughly to grab a span, then fine-tune to the exact second with the end handles. Turn on fade in/out and the cut eases in and out instead of stopping abruptly.
