SAMPLE LOOP FINDER

A local audio analyser that ranks loop boundaries from BPM and bar length, auditions candidates and exports a crossfaded WAV.

The ranking narrows the search; it does not replace listening. Check the beat, harmony and ambience at every boundary.

What this browser tool does

A local audio analyser that ranks loop boundaries from BPM and bar length, auditions candidates and exports a crossfaded WAV.

First five steps

  1. Load or drop an audio file.
  2. Enter BPM and choose one, two, four or eight bars.
  3. Move SEARCH AREA and press ANALYZE.
  4. Audition ranked candidates in LOOP mode.
  5. Adjust crossfade and export LOOP WAV.

Basic controls

BPM / LENGTH

Bar duration assumes four-four time.

SEARCH AREA

Choose the part of the file where stable playing occurs.

CANDIDATES

MATCH measures boundary similarity, not musical quality.

CROSSFADE / A-B

Compare positions or lengths and use crossfade only as needed.

Practical setups

Four-bar drums

Use a correct BPM and a short 10 to 30 ms crossfade.

Ambience

Use a longer loop and 80 to 180 ms crossfade.

Bass or pad

Reject boundaries where harmony cannot return even when MATCH is high.

Save and export
