BPM
If the clicks drift away from the drums, the tempo is off. If they land on every other beat, or twice per beat, choose the other number above.

How to use BPM Finder
- Choose a songPress Choose a song or drop the file into the box. The tempo appears in a few seconds.
- Check it by earPress Play with a click on each beat. If the clicks match the drums, the BPM is right; if they fall on every other beat, choose the half-time or double-time number.
- Or tap alongChoose Tap along and tap the pad, or any key, on each beat. After four taps the BPM appears, and it gets more exact the longer you tap.
Drop in a song and the BPM Finder listens for its beat and shows the tempo in beats per minute, with how confident it is and the half-time and double-time counts musicians also use. Press play to hear the song with a click on every beat, so you can tell straight away whether the number is right. No file to hand? Switch to Tap along and tap the pad, or any key, in time with the music. It opens MP3, WAV, M4A, AAC, OGG, Opus and FLAC files, and everything happens in your browser, so your music is never uploaded.
BPM means beats per minute: how many times you would tap your foot in a minute of the song. DJs use it to mix tracks at matching speeds, producers to set a project's tempo, dancers and runners to pick music at the right pace, and musicians to practise with a metronome. This BPM finder measures it from the song itself.
How the tempo is found
The tool listens for the moments when new sound starts, such as a kick drum, a snare hit or a chord, separately in the bass, the middle and the treble. It then looks for the gap between those moments that repeats most regularly across the song, and measures that gap precisely over many beats. The same pattern also tells it where the beats fall, which is how the click track lines up with the music.
Reading the result
- Confidence says how steady and clear the beat was. High means the song repeats very regularly at that tempo; low means check it by ear.
- Half-time and double-time are the same beat counted differently. A DJ may call a track 174 BPM while a rapper over it feels 87. Pick the one that matches how you count.
- The click track settles any doubt: if the clicks stay locked to the drums from start to finish, the tempo is right.
When to tap instead
Tap along is best for a song that is playing somewhere else, such as on the radio or in a video, and for music without drums, where there is little for the detector to hear. Tap steadily for about ten seconds; the count uses your most recent taps, so a slip at the start soon stops mattering.

Questions
How do I find the BPM of a song?
Choose the song file and the tempo appears in a few seconds. Press Play with a click on each beat to confirm it: the clicks should land on the kick and snare drums. Without a file, choose Tap along and tap in time with the music.
How accurate is it?
It works best on music with a steady beat, such as pop, dance, hip-hop and rock, where the number is normally exact or within a fraction of a BPM. Songs with no drums, a changing tempo or a very loose feel are harder, and the confidence line says when the beat was unclear. The click track is the quickest way to be sure.
Why does it show half or double the tempo I expected?
The same song can be counted two ways: drum and bass is often called 174 BPM or 87 BPM, and some slow songs are counted at double speed. Both are the same beat. The tool shows the other count under the result, and you can switch to it with one click.
What if the song speeds up or slows down?
The tool finds the main tempo, listening to up to four minutes from the middle of the song. Live recordings that drift give a rough average; tapping along during the part you care about gives the tempo of just that part.
How does tap tempo work?
Each tap is timed, and the BPM is the average gap between your most recent taps. Four taps give a first reading, sixteen give a steady one. If you stop for more than two seconds, the next tap starts a new count.
What BPM are common music styles?
As a rough guide, hip-hop often sits around 80 to 100 BPM, pop around 100 to 130, house around 120 to 130, and drum and bass around 170 to 175. Individual songs vary, which is why measuring the actual track helps.
Can it find the key of a song?
No, it finds the tempo only.
Is my music uploaded?
No. The song is opened and analysed by your browser on your own device, and it is never sent to us or anyone else.
Is it free?
Yes, completely free, with no sign-up and no limit on the number of songs.
