Loop Point Finder

Pick rough start and end points; the tool snaps to the nearest zero crossings so the loop plays seamlessly.

About this loop point finder

Audio loops click at the seam unless the start and end land on zero crossings — moments where the waveform is at zero. Pick rough timestamps, this tool snaps each one to the nearest zero crossing within ±50 ms, and exports a clean loop you can repeat without an audible click.

Useful for game audio, ambient music, meditation tracks, sleep sounds and any case where audio needs to repeat seamlessly. Pairs well with the Audio Looper which then extends the result to a target duration.

How to find loop points

  1. 01

    Drop in audio

    Best with simple looping content — pads, ambience, single notes.

  2. 02

    Pick rough start + end

    Use the sliders. The tool will snap each to the nearest zero crossing.

  3. 03

    Download the cleaned loop

    The output starts and ends at zero crossings — repeat it as long as you like.

Why use this loop finder

  • Snaps to zero crossings within ±50 ms of your pick
  • Output keeps the same format as the input
  • Works with common audio formats
  • Free, private, no install
  • No watermark, no signup
  • Useful for game audio, ambient music, meditation tracks, sleep sounds

Loop finder FAQ

Why do my loops click without this?

If the audio level at the loop's end doesn't match the level at its start, you hear a discontinuity — the click. Zero crossings are moments where the waveform passes through zero amplitude. Cutting at those points gives a click-free seam.

Will it work with stereo?

Yes — but the snap looks at the mono sum of both channels, so for highly decorrelated stereo content (very different left vs right) you may still hear a small click. Try a mono version for the cleanest loop.

What about a crossfade instead?

Crossfade is a different technique — it smooths the seam by blending the end into the start. Useful when the audio doesn't have natural zero crossings. The Crossfade Joiner tool covers that case.

Is the audio re-encoded?

Yes — the slice is re-encoded once. Lossless inputs (WAV, FLAC) keep their format. Lossy inputs go through one re-encoding pass.
