How it works

Three steps. Seconds, not minutes.

    Drop a song

    It takes a few seconds to find the tempo, the bars and the hits.

    Every beat, each bar, or the hits. Set the frame rate to match your timeline.

  3. 03

    Export

    Download a CSV with timecodes, an Audacity label track, or copy the times.

Why this one

Built by the people behind Razzle. Made for people who post.

Hits, not just a grid

Most beat tools give you a metronome. This also finds the real hits, so cuts land on the snare, not near it.

Timecode-ready

HH:MM:SS:FF at 24, 25, 30 or 60 fps, so markers line up with your sequence in Premiere, Resolve or Final Cut.

Files that open anywhere

CSV for spreadsheets and scripts, Audacity labels to check against the waveform, plain times for anything else.

Beats, bars or hits

Three kinds of marker. Pick the one your edit needs.

  • Every beat

    The steady pulse of the song's tempo. For fast montages and quick cuts.

  • Each bar

    Every fourth beat, starting on the strong one. The safest place to change scene.

  • Hits

    Where the sound actually jumps: snares, stabs, drops. Follows fills and breaks a grid misses.

No. Your browser decodes and analyses the file itself. Nothing is sent to a server, so it's fine for unreleased tracks and client music.
