Free BPM Finder: Find the Tempo of Any Song

Yes, this one. Use the BPM finder free, with no sign-up and no watermark. Because the analysis runs in your own browser, there is no server queue and no cost to us for each song, so a free tempo finder built this way stays free.

It measures the tempo. BPM finder, BPM detector and tempo detector are three names for the same job: telling you how fast a piece of music is, in beats per minute. It finds the moments where the sound jumps in energy, works out how regularly they repeat and turns that spacing into a tempo: a beat every half second is 120 BPM. This one also finds the first beat and plays a click on the grid so you can check the answer.

Drop the song into the tool at the top of this page. It detects the tempo in your browser and shows the BPM with ÷2 and ×2 readings; press play with the click on to check it. No file? Count the beats for 15 seconds and multiply by 4, or tap along on tap tempo.

On music with a steady beat, usually yes: the detected tempo matches what a musician would count, apart from the half or double question. It is less reliable on rubato, live recordings that drift and songs that change tempo, where one number can only be an average. We will publish measured results once our tests are done; until then, the click track is the honest check of an accurate BPM finder.

With a clean file and a steady beat, automatic detection is more precise: it measures the whole song to a decimal, while taps carry your own timing. Tapping wins when there is no file, when the beat is soft, or when the music speeds up and slows down. Many people use both: detect first, then tap to confirm.

Because a beat can be counted at more than one level. A hip-hop track at 90 has hi-hats at 180, and drum and bass at 174 has a backbeat that feels like 87. The detector leans toward the level most listeners count; press ÷2 or ×2 (or H and D) to switch to the one your DAW, DJ software or class expects, or set a BPM range so a whole batch folds into the range you count in.

Yes. To get the BPM from an MP3 or find the tempo of an MP3 stem, just drop it in; WAV, M4A, FLAC, OGG, the soundtrack of an MP4 or MOV video and most formats your browser can play work the same way, up to 200 MB each, with the first 10 minutes analysed. A MIDI file works too: its tempo comes from the file itself. Of everything people bring to a BPM finder, MP3 files are the most common, and to a BPM calculator, MP3 or WAV makes no difference: both are decoded to the same audio first. Producers use it as an MP3 tempo finder for samples and loops, and rappers as a beat BPM finder for instrumentals they are about to write over.

Yes. Select or drop several files and each gets a row with tempo, confidence, first beat, downbeat, key and Camelot code. Sort it, copy it or export CSV to keep the numbers with your library: a quick song BPM check for a whole set.

Not in the neural network sense. It uses signal processing: an onset detector and a search for the beat period that repeats most strongly, the same family of methods DJ software has used for years. That keeps this online tempo finder fast, private and predictable, and when it is unsure, its confidence score says so.

Not from a link. This page analyses audio files and recordings, and streaming services do not hand their audio to other sites, so it is not a Spotify or SoundCloud BPM finder. If you own the track as a file, drop it in. If you can only stream it, play it and tap along on tap tempo, which works with anything you can hear.

You get one main tempo per file, the one that fits most of the song. On clips of 30 seconds or more the result also says whether the tempo stayed steady or moved, and between which BPMs. If a song switches tempo, trim each section into its own file and analyse them separately, or tap along with each part; the click track drifts off where the tempo moves.

No. There is nothing to install: this BPM finder online runs in a modern browser on a computer or a phone, so you do not need a separate BPM detector app. Bookmark it and it opens like one.

The result already lists them: delay times for every note value from a whole note to 1/32, straight, dotted and triplet, each copied with a click, so there is no separate delay time BPM calculator needed. The maths is one line, the same any delay BPM calculator uses: 60,000 divided by the BPM is one beat in milliseconds. At 120 BPM a quarter note is 500 ms, an eighth 250 ms and a dotted eighth 375 ms.

Most popular music sits between about 70 and 140 BPM. Typical ranges: hip-hop 80 to 100, pop 100 to 130, house 120 to 128, techno 125 to 140, drum and bass 170 to 175. Use them as a sanity check rather than a rule: a house track that reads 64 is almost always half time.

Yes, as a second reading: the result shows the key with its Camelot code and a confidence score. For key-focused work, such as key changes and the keys that mix with a song, use the key finder and the Camelot wheel.

No. The file is decoded and analysed inside your browser and never leaves your device; close the tab and it is gone. Only analyse audio you have the right to use.
