1. Load your audio
Drop a file into the tool. It stays on your device while the browser decodes it and draws the waveform.
Shorter source files use less memory, so trim very long recordings before you begin when possible.
2. Choose the start and end
The highlighted region is your candidate loop. Drag its edges and listen until the musical phrase or ambience feels complete.
For rhythmic material, align the points with the beat. For ambience, choose places with similar volume and texture.
3. Tune the crossfade
Start with the automatic setting and preview the processed loop. Increase it if you still hear a click; shorten it if an attack becomes blurred.
Because the end and beginning overlap, the finished cycle is slightly shorter than the selected range.
4. Pick a format and export
Choose WAV for editing and lossless quality, MP3 for easy sharing, or Opus for a smaller modern file where supported.
Export one cycle for a DAW or game engine, or set a repeat count for a ready-to-use background track.
