د کارولو طریقه Audio fade editor

The audio fade editor applies a fade-in at the start and a fade-out at the end of an audio file, each up to 60 seconds long, and exports a 16-bit WAV. The fade-out position is calculated from the source duration you enter, so set that length in seconds. Video files work too; only their audio track is kept.

Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
Set fade-in seconds, fade-out seconds, source duration (seconds; for fade-out position).
Run audio fade editor, review the output, then use the available copy or download controls.

Applies fade-in and fade-out using the duration you enter. Check the actual source duration to place the fade-out correctly.

Fade-in seconds: Range: 0 to 60

عامې پوښتنې

Why does my fade-out start in the wrong place?

The fade-out begins at the source duration you enter minus the fade-out length. If that duration does not match the real file, the fade lands early or late. Check the actual length in a media player and enter it in seconds.

Can I add only a fade-in to an audio file?

Yes. Set Fade-out seconds to 0 and only the fade-in is applied; the same works the other way round. Together, the two fades cannot be longer than the source duration you entered.

What format does the audio fade editor export?

It writes faded.wav using 16-bit PCM. The output must stay under 50 MB and processing stops after 180 seconds, so very long recordings may need to be trimmed first.

Where is my input processed?
