Step 1
Add your audio
Drop one audio file here, or browse your device. Everything stays in this browser.
Your file is decoded, rendered, and exported locally in your browser. Nothing is uploaded.
Audio fade guide
Smooth transitions without installing software
Use a short fade-in to remove a hard start and a fade-out to finish music, voice, or sound effects naturally. The waveform makes both transition points easy to see before you render the result.
Set the fade length
Drag the colored waveform handles or enter exact fade-in and fade-out durations.
Preview and export
Render with Web Audio, listen to the result, and download a lossless WAV file.
Are my audio files uploaded?
No. The browser decodes the selected file and renders the result on your device. The source file is never sent to the server.
Why is the result exported as WAV?
WAV keeps the rendered PCM audio lossless after the gain automation. You can convert the result to MP3 or another delivery format afterward if needed.
