How to use the Audio Fade In & Out

  1. Choose an audio file.
  2. Set the fade-in and fade-out lengths.
  3. Pick a curve shape, preview and download.

What does this tool do?

Fades stop a clip from starting or ending abruptly — essential for ringtones, video background music, podcast intros and trimmed songs. The S-curve sounds the most natural; logarithmic fades drop quickly at first, exponential ones start gently.

Audio is processed on your own device and never uploaded. Results download as lossless WAV, which plays on every device.

Why use it?

  • Separate in and out lengths.
  • Four curve shapes.
  • Instant preview.
