Upload audio to fine-tune seamless loops with visual waveform feedback
or drag & drop audio file here
Supports: MP3, WAV, OGG, AAC
Select or drag & drop your audio file. Supported formats include MP3, WAV, OGG, and AAC.
Adjust the loop start and end points using the sliders or by clicking on the waveform.
Use fade in/out to smooth transitions and snap to zero crossings for seamless loops.
Play your loop to hear how it sounds and continue adjusting until it's perfect.
See exactly where your loop points are set with the interactive waveform display.
Fine-tune loop points to the millisecond for perfect seamless loops.
Automatically snap to zero crossings to eliminate clicks and pops in your loops.
Smooth transitions with customizable fade in and fade out times.
The tool supports common audio formats including MP3, WAV, OGG, and AAC. For best results with looping, uncompressed formats like WAV are recommended.
A zero crossing is where the audio waveform crosses the zero amplitude line. Starting and ending loops at these points helps prevent clicks and pops in the audio.
1) Find a section where the end matches the beginning musically. 2) Use the zero crossing feature. 3) Add small fade in/out if needed. 4) Test repeatedly until it sounds seamless.
This tool is for testing and perfecting loops in your browser. For exporting, you'll need to use audio editing software with the loop points you've determined here.
Clicks usually occur when the loop points don't match in amplitude or phase. Try the zero crossing feature, adjusting the points slightly, or adding very short fades (5-20ms).
