What is a SMPL Chunk?

A SMPL chunk is metadata within a WAV file that contains information about the sample, including its root note. When you add this information to your samples, DAWs like Ableton Live can automatically detect the correct pitch of your samples.

How to Use This Tool

  1. Name your WAV files with the note information (e.g., "Kick_C3.wav" or "Bass_F#2.wav")
  2. Drag and drop your files into the area above (or click to select files)
  3. Verify that the detected notes are correct
  4. Click "Process & Download All" to add SMPL chunks to all files
  5. Use your processed samples in Ableton with automatic key detection
