Frequently asked questions
Is the audio fade tool free?
Yes. It is completely free, with no sign-up and no limits.
Are my audio files uploaded to a server?
No. Your audio is decoded, the fade envelope is applied to the waveform, and the result is exported as WAV entirely in your browser. The file never leaves your device.
What kind of fade is applied?
An equal-power fade is used, which sounds smooth and natural for both fade-in and fade-out.
What output format does it produce?
The result is exported as a WAV file, which is universally playable and preserves the full quality of the processed audio.
