Frequently Asked Questions
- What is a fade?
- A gradual rise (fade-in) or fall (fade-out) in volume at the start or end of a file — the standard way to make tracks end cleanly.
- Which curve should I pick?
- Linear is natural and works for most material. Quarter sine is gentle. Exponential is great for songs fading into silence.
- Does it work on video files?
- Yes. Video is copied untouched; only the audio track fades.
- Can I set only one side?
- Yes. Set the other side to 0 and only the chosen fade applies.
Using Our Fade In / Fade Out Tool
Fades are the simplest, most-used audio production technique. A fade-in eases the listener into a track. A fade-out lets it end cleanly instead of cutting off abruptly. Our Fade In / Fade Out tool adds both to any audio or video file — entirely in your browser, no uploads.
When to Use Fades
- Music tracks: 2–4 seconds for a classic ending.
- Podcast intros: 0.5–1.5 seconds to ease in the theme.
- Voice-over: 0.2–0.5 seconds to avoid a hard start.
- Video soundtracks: fade under a cut to hide the seam.
Curve Shapes Explained
Linear is the default for a reason — it sounds natural. Quarter sine has a gentle S-curve and works well for orchestral pieces. Exponential fades are popular for pop songs — the tail disappears gracefully. Logarithmic fades are for the start of ambient or transition tracks.
Video Support
Drop a video file and the video stream is copied untouched while the audio fades. That means no re-encoding, no quality loss, and it happens in a fraction of the time of a full video render.
