How This BPM Finder Reads a Song's Tempo
A BPM finder, also called a tempo finder, counts a song's beats per minute. This one decodes your file in the browser, runs beat detection and rounds the tempo to a whole number. It looks for a tempo between 90 and 180 BPM, so a slow ballad can come back at double its felt speed. Nothing leaves your device.
What the BPM Finder Gives You
One tempo, a tempo marking, and a warning when the beat is unclear.
A Whole-Number BPM From Your File
The BPM finder returns one tempo for the whole track. If the song changes tempo, you get the figure that fits most of it.

BPM Finder FAQ
Answers about finding a song's tempo from an audio file.
What does a song BPM finder show?
A song BPM finder shows tempo in beats per minute. This one returns a whole-number BPM and a tempo marking such as Andante or Allegro.
Why is my BPM finder result double or half what I expected?
Beat detection looks for a tempo between 90 and 180 BPM, so a slow ballad that reads 140 is probably 70, and a fast track that reads 90 may be 180. Halve or double the figure if it does not match.
How accurate is this BPM finder?
The BPM finder works best on music with a steady, clear beat. Sparse rhythms, free timing and tempo changes can give a wrong or ambiguous number, so check anything important in your DAW. No accuracy percentage is shown.
Which audio files can the BPM finder read?
The BPM finder reads MP3, WAV, FLAC, OGG, AAC, M4A and WebM files up to 80 MB, and up to 10 minutes on desktop or 5 minutes on mobile.
Is the BPM finder free, and is my song uploaded?
Yes, it is free with no account. And no, your file is never uploaded: decoding and beat detection run in your browser.
Can the BPM finder take a YouTube or Spotify link, or tap along?
No. This BPM finder cannot take a link or a tap; it reads an audio file you choose.
Where does the sample song come from?
The sample is a 25-second clip of "Got Funk" by Kevin MacLeod (incompetech.com), licensed under Creative Commons: By Attribution 3.0, http://creativecommons.org/licenses/by/3.0/. The full recording is on Wikimedia Commons.
Does this page also find the key of a song?
No. This page gives tempo only. The Key Finder page returns the key, scale and related keys.
