Fade Audio
âšī¸ How it works:
- Upload your audio file
- Set fade in and fade out with the sliders
- Download the result in the same format
Add Fade In and Fade Out to Audio Online
Give your audio a smooth start and ending. A fade in gradually raises the volume from silence at the beginning, and a fade out eases it back down to silence at the end — no more abrupt starts or hard stops. Set each fade with a slider, and download the result in the same format you uploaded. No sign-up and no watermarks.
How to Fade Audio
- Click the upload area above or drag and drop your audio file (up to 10 MB).
- On the next screen, set the fade in and fade out length with the sliders (0 to 10 seconds each). You can also play the original to judge the timing.
- Apply the fades and download your audio.

Frequently Asked Questions
Fade in raises the volume from silence to full at the start of the audio. Fade out lowers the volume from full to silence at the end. You can use either on its own, or both together.
Each fade can be set from 0 up to 10 seconds, in 0.1 second steps. The fade in and fade out combined can't be longer than the track itself.
No. A fade only shapes the volume at the start and end — the rest of the audio is untouched, and the file is saved back in its original format.
You can upload MP3, WAV, OGG, FLAC, AAC, M4A and WMA up to 10 MB, and the result downloads in the same format. (WMA files are returned as WAV.) Need a different format afterwards? Use our Convert Audio tool.
