Fix BPM drift. Lock any song to a steady grid.

Some songs just won't sit still. They rush the chorus, drag through the breakdown, and drift off the grid. BPM Lock takes the drift out, stretching every beat onto one steady BPM with the pitch untouched.

Eight beats, before and after

CH1 Input

Beats land where the band played them. The grid slips further out every bar.

CH2 Output

Every beat rewritten onto the grid. Same performance, same pitch, steady tempo.

The same performance, with the timing corrected. Check the detected beats before you render.

How it works

  1. Drop a track. Open WAV, MP3, FLAC, AIFF or M4A. Nothing is uploaded.
  2. Check the beats. Listen against the click and adjust any markers that miss.
  3. Render and download. Get a steady-tempo WAV, AIFF or MP3 for your DAW or DJ library.

  • LVNLIFE

    ⭐⭐⭐⭐⭐ Excellent tool for DJs & Producers! This website locks in BPM and fixes older tracks that drift in tempo, making beat matching smoother and mixing easier. A real game-changer for any DJ or Producer looking to keep their sets tight and seamless. Highly recommended! I personally use BPM lock everyday which helps me remix faster, easier, and more efficient. A huge time saver that streamlines the creative process!

What a locked file is for

  • Acapellas that stay in time

    Correct the full mix before splitting stems so the vocal follows the same steady grid.

  • Remixes, edits and mashups

    Crop to bar 1 and drop the locked file into your session at its detected BPM.

  • DJ sets and library prep

    Keep long blends and loops in time. Export the matching Rekordbox XML to bring the grid with you.
