Give a track a gentle start and a proper ending instead of a hard cut — with a curve that suits the material.
The fade is applied to the actual samples, so what you hear in the preview is exactly what the downloaded file contains.
A fade is the difference between audio that stops and audio that ends. This tool adds one at each end of a file and lets you choose the shape it follows.
A fade in lifts the volume from silence at the start; a fade out takes it back down at the end. Set either to zero to skip it. The curve decides how the volume moves between the two: a straight line changes at a constant rate, an S-curve eases in and out at both ends and is what most music wants, and the two lopsided curves are useful when you need the change concentrated early or late.
Fades are applied directly to the decoded samples before saving, so there is no guessing — the preview player is playing the finished result.
The S-curve for music — it is the least noticeable. A straight line for speech and short clips, where you want the change over and done with. The lopsided ones are for effects, or for ducking under something else quickly.
A second or two at the start and two to four at the end covers most music. For speech, a few tenths of a second is plenty — long fades on a voice sound like a mistake.
Not with this tool, which works on the two ends. To fade into a section, trim the piece you want first and then fade that.
No. The fade is applied to audio that is already there, so the length is untouched. If you want to shorten the file as well, trim it first.
The fade in is capped at the file length, and the fade out takes whatever is left after it, so nothing breaks — but a fade longer than the audio means the whole thing becomes a ramp.
