Find Your Song’s Tempo.

How to find the BPM of a song

1. Open the BPM finder

   Go to the free BPM finder on the home page and upload a track from your device. The audio tempo detector accepts common music formats, including MP3, WAV and FLAC.

2. Run tempo detection

   Once the file is prepared, choose Find pitch / tempo. Analysis covers the full recording within the five-minute upload limit.

3. Read and use the result

   The chat highlights the estimated tempo in BPM alongside the musical key. Keep the result, change the track’s speed, or finish the chat.

What does BPM tell you?

Full-track analysis, with room for musical judgment

This tempo finder considers the entire prepared recording rather than only the preview excerpt. It combines estimates from sections of the track into one overall BPM value. A live performance that speeds up or slows down may not have one tempo that fits every bar.

Half-time and double-time interpretations are common: 70 and 140 BPM can describe different levels of the same rhythmic pattern. Weak drums, syncopation, long ambient passages and changing time feel can also make automatic BPM detection uncertain. Some recordings have no clear beat to detect.

For a quick listening check, count the beats you hear for 15 seconds and multiply by four. Our tool analyzes uploaded audio; it does not listen through your microphone or provide a tap-tempo pad.

From a tempo reading to a track you can use

If a recording is too fast for practice, our tempo changer overview explains how to slow it down while keeping its pitch. For example, 120 BPM at 80% becomes approximately 96 BPM. Open the audio tool on the home page to preview the change before exporting the whole file.

Need to understand the harmony too? The song key finder explains the major or minor key shown with your BPM result. Both readings are available in the same analysis.

You can also start from the Pitch Tempo home page and choose between finding key and BPM or changing the audio after upload.
