Fade your audio in and out
for a smooth start and finish.
Fade audio in and out with one setting that softens both ends, while the middle of the track stays at its original volume.
A fade stops the music slamming in on the first photo or cutting off mid-note on the last. It’s the finishing touch for a wedding slideshow, a work presentation or the music under a travel video. The audio cutter fades the start and end of whatever range you select, then saves that range as a WAV.
Set your range and fade length
- Open the track. In the audio cutter, select Choose a file and pick your song or soundtrack.
- Choose the range. Start (seconds) begins at 0 and End (seconds) is already filled in with the full length, so leave both alone to fade the whole track. Type new times if you only want part of it.
- Set Fade each edge (seconds). Try 1 for a gentle start and finish. You can go anywhere from 0 to 5, and the same length is used at both ends.
- Press Play. Listen from the first note to the last. If the start feels sleepy or the ending feels abrupt, change the fade and play it again.
- Click Download WAV. Then bring the file into your slideshow or video editor.
What the fade actually does
A setting of 2 gives you a two-second fade-in and a two-second fade-out. Everything in between stays at its original level. The fades happen inside your selection, so you won’t get extra silence before the song or a tail added after the last note. If your selection is shorter than the two fades put together, each one simply takes half of it.
Pay attention to the first beat. A longer fade eases the music in; a shorter one lets the opening land. At the end, listen for the last word, chord or cymbal ring, and set your end point a little after it so the fade doesn’t swallow the finish.
Time the fades to your pictures
In a wedding slideshow, let the first photo settle before the main tune comes in. At the end, decide whether the music should stop with the last photo or carry on under the closing title. Pick your start and end around that, then fine-tune the fade length.
Drop the WAV onto your editor’s timeline and watch it with the real pictures. When you try a new version, put it in the same spot on the timeline so you’re comparing fades, not accidentally moving the music.
Always start again from the original
When you want a different range or fade, go back to the original file. Fading a file that’s already faded stacks the two, and the ends come out quieter than you meant. Each download is named after your file with -cut on the end, so rename the versions you keep, like “slideshow-ending-1s.”
Last check: play it on the speakers or TV that will actually play the slideshow. Make sure the opening is loud enough to notice and the music reaches silence right when you want it to.
