Fade Out Audio
Set how many seconds should fade at the end. Listen to the result, then save it as MP3 or WAV.
Your audio stays on your device. No server upload.
Adjust the settings and compare the actual result.
Each tool lists its supported formats and limits.
Give music a smooth ending
Fade out audio by gradually reducing the volume during the final seconds of a track. Choose the duration, listen to the processed ending and save as MP3 or WAV. The tool keeps the full track length and works from your original input file. Your selected recording stays in your browser.
How to fade out audio online
- Choose an MP3 or uncompressed PCM WAV, or try the bundled music sample.
- Set the fade duration. Start with three seconds and adjust after listening. Quick presets offer one, three, five and ten seconds.
- Select MP3 or WAV export. For MP3, choose 128, 192, 256 or 320 kbps.
- Create your audio. Compare Play original ending and Play processed ending.
- Download the exported file. Save it before closing, refreshing or leaving this page.
Choose the right fade-out duration
The fade begins at the track duration minus the fade duration. A five-second fade on a sixty-second track starts at fifty-five seconds and ends at silence. The timeline shows the final portion that will change. Everything before that portion is left at its existing level before encoding.
A short fade can soften an abrupt cutoff. A longer fade can help a sustained musical phrase settle. Listen for the last word if you are editing speech, and for important notes at the end of a music track. There is no automatic beat detection or musical phrase alignment, so the final choice is yours.
Custom fades are allowed from 0.5 to 30 seconds, bounded by the input duration. For recordings shorter than half a second, you can use the full duration. Learn more in the guide to fading out music.
MP3 or WAV output?
MP3 gives a smaller file with a choice of CBR bitrate. It is a lossy format, so another encoding can introduce additional compression artifacts. If you need a bitrate change as well as a fade, make both changes in this workbench to avoid a chain of intermediate MP3 exports.
WAV export uses 16-bit PCM and takes more space. It avoids another MP3 compression pass but does not restore information missing from an MP3 source. The output keeps 48 kHz for a 48 kHz source and otherwise uses 44.1 kHz. See the MP3 bitrate guide if delivery size is the priority.
What this tool supports
Use mono or stereo MP3 and uncompressed PCM WAV files up to 30 MiB and ten minutes. A browser audio engine downloads on first use. Processing happens locally; available memory and speed vary by device. On a phone or a device with limited memory, try a short recording first and keep the tab open until processing finishes.
Fade-out audio questions
Does fading shorten my song?
No. The fade changes volume within the original duration. MP3 encoding may add a small amount of framing or delay. This tool does not trim audio or choose a new endpoint.
Which fade curve does it use?
It uses a linear amplitude fade, ending at silence. Custom curves, fade-in and crossfades are not currently available.
Why is the change hard to hear?
The original may already end quietly or contain silence. Compare the last ten seconds and try a different fade duration. Playback volume and the musical material also affect what you hear.
Can I fade and change bitrate together?
Yes. Choose MP3 and select a bitrate here. Both operations use the original file in one export. The separate MP3 bitrate converter also offers the fade setting.
What if the file fails to process?
Check its format, size and duration, keep this tab open and try again with a shorter file. Cancel stops the current processing task; there is no cloud fallback. See Help & contact for more steps.
For a size-focused workflow, use Compress MP3 and the file-size guide. Start from a PCM recording with WAV to MP3.
