Smooth starts and endings
A recording that starts or stops abruptly sounds unfinished, and a song cut in the middle can end with a jolt. A fade in lets the sound rise gently from silence; a fade out lets it drift away. Echoly does both in one window with live preview.
How long should a fade be?
For speech and voice notes, 0.5 to 1 second is enough. For songs and background music, 3 to 6 seconds at the end sounds natural. Ringtones and alarms usually need 1 to 2 seconds at the start.
Fade only a part
Select a section first to fade just that part, for example the last ten seconds of a song you shortened, or the point where background music should enter.
One-click fades for quick edits
For a single fade, select the part and choose Effects → Fade in or Fade out (keys I and O on a computer). The fade window is best when you want both ends done precisely.
