How to use it
- Open your audio.
- Select from the start to where the fade should reach full volume, or type the length in Clip → Fade in.
- Choose a curve: linear sounds natural for short fades; equal-power holds the level up longer and suits music.
- Press Fade in (I). The waveform redraws with the envelope applied.
- Play from the start to check, then export.
How long should a fade in be?
For removing a click at the start of a cut, 5–20 ms is enough and inaudible as a fade. For an intro to swell in, 2–6 seconds is typical. Ringtone and alarm presets use 0.5 and 3 seconds respectively. Fades are measured in samples on the clip, so the length you type is exactly what you get.
A fade in on a selection that starts in the middle of the track splits the clip at the selection edges and fades only the selected part, leaving the rest at full level.
Questions
Linear or equal-power?
Linear rises at a constant rate and sounds slow to start. Equal-power (sine) rises quickly at first, which sounds smoother for music. Try both; undo is instant.
Can I fade in and out on the same clip?
Yes. Set both lengths in the Clip panel. If they would overlap, the fade out is shortened.
Does a fade change the original file?
No. Fades are stored as clip settings and applied when you play or export.
