How a BPM Tapper Turns Taps Into Tempo
Tap, tap, tempo: every tap is a timestamp. A BPM tapper measures the gaps between your taps, averages them, and divides 60,000 by the average gap in milliseconds: taps 500 ms apart make 120 BPM. One gap on its own is noisy, because no hand is a drum machine, but the average of eight or more settles fast. That is why tapping works on anything you can hear, from a stream to a band in the room, where there is no file to analyze. Without it, you are left with this:
- Streaming apps, the radio and live bands never show you the BPM.
- Counting beats against a stopwatch is slow, and one missed beat in 15 seconds puts you 4 BPM out.
- An automatic detector can read a trap song at 70 when you feel 140.
- A delay set by ear smears the vocal instead of echoing on the beat.
- Cut points guessed in seconds drift off the music by the second chorus.
Why Editors and DJs Tap BPM Here
An online tap tempo tool for people who need the number for something: a cut, a blend, an echo, a count-in.
Tap with anything
A beat tapper that takes Space, Enter, T, a mouse click or a finger on a phone screen. The pad is big enough to hit without looking while your eyes stay on the timeline.
A stability meter
See how even your taps are. When the meter reads steady, the tempo has settled and you can stop tapping.
Resets itself between songs
Pause for two seconds (or the gap you set) and the next tap starts a new count, so you can go from track to track without reaching for a button. Esc clears it at once.
A metronome at your tempo
Play the tapped BPM back with an accent on beat one, in 2/4 up to 7/8, with eighths, triplets or sixteenths if you like, and hear it against the song.
Delay and reverb times
Every note value from a whole note to 1/64, straight, dotted and triplet, in milliseconds and Hz, each one a click away from your clipboard.
Free, private, no microphone
Nothing is recorded or uploaded: the tapper only listens to your hands. Free, with no sign-up and nothing to install.
How to Tap Tempo Online in Four Steps
Tap to find tempo in about ten seconds. Like any BPM calculator, tap by tap, it needs no file and nothing to install.
Start the song in any app, or let the band play. Headphones help you hear the beat over your own tapping.
Tap to the beat with Space, Enter or T, a click on the pad or a touch on a phone, once per beat: the kick, or the beat you would clap to.
A BPM appears on the fourth tap. Keep going for eight or more, until the stability meter reads steady; a stray tap is left out on its own.
Start the metronome to check it against the song, copy the BPM, or read off the BPM in ms for your note value.

From Tap BPM to Delay Times and Cut Points
Tapping gets you the number. The rest of the page turns it into something you can set, cut or play.
A tap pad that keeps up
Tap with Space, Enter, T, a click or a touch. The BPM updates on every tap from the average of your last 4, 8 or 16 taps (or all of them), a Last 4 reading shows where you are right now, and a stability meter and a timing graph show how early or late each tap landed. A tap far off the beat is left out instead of dragging the average. Stop for a moment and the next tap starts fresh, so you can tap the tempo across a whole playlist without a reset button. A BPM tap counter, a tap tempo finder and a BPM button in one pad: tap online, BPM in seconds.
Tap the PadA metronome with accents and time signatures
Play the tapped tempo back as a click with beat one accented, in 2/4, 3/4, 4/4, 5/4, 6/8 or 7/8, with eighths, triplets or sixteenths between the beats and a wood, beep or hat sound. It follows your taps, or type a BPM by hand. Start it while the song plays: if click and drums stay together for a few bars, your tap BPM is right. Drummers use it for a count-in; editors use it to hear where the bar lines fall before they cut.
Start the MetronomeDelay and reverb times for every note value
The BPM tap calculator shows your BPM in milliseconds for every note from 1/1 to 1/64, straight, dotted and triplet, plus the same values in Hz for LFOs, tremolo and auto-pan. Click a value to copy it into a delay plugin or a pedal. At 120 BPM a quarter note is 500 ms, a dotted eighth 375 ms and an eighth-note triplet 166.67 ms. A reverb table sets pre-delay and decay so the tail ends on a note value: a hall on a whole note, a small room on a quarter, a tight ambience on an eighth.
Get Delay TimesBeat and bar lengths for video cuts
In 4/4 a whole note is one bar, so the 1/1 row is your bar length: 2,000 ms at 120 BPM, which is 60 frames at 30 fps. Cut every bar for a calm montage and every beat for a fast hook. In a photo music video the cuts follow the beat for you, and a lyric video maker syncs each line of words to the song.
Find the Bar LengthHave the file? Check it in the BPM finder
Tapping is best for music you can hear but not open. When you have the song as a file, the BPM finder measures it to two decimals with a click track and a beat grid. Looking for a BPM calculator for an MP3? That is the one. With a file, trust the BPM finder; tap here for streams and live sound, and use both to compare when a reading looks odd.
Tap Here FirstA BPM Tap Session, Tap by Tap
Twelve taps in the online tempo tapper along to a song at 120 BPM: the gaps, the average and what it shows.
What you are looking at
The first gap was 512 ms and the third 486 ms: single taps wander by a few hundredths of a second. The last eight gaps averaged 499.6 ms, so the reading settled at 120.1 BPM and the stability meter read steady. Check it yourself: 60,000 ÷ 499.6 = 120.1. Produced songs almost always sit on a whole number, so call it 120. From there the delay row reads 500 ms for a quarter note, 375 ms for a dotted eighth and 2 seconds for a bar.
How Many Taps Does a BPM Tapper Need?
Fewer than you think, as long as they are even. Any tempo tapper online works the same way: each tap wanders a little, the average cancels most of it, so the longer you tap, the closer you get.
Four taps: a first guess
Three gaps give a reading good enough for a rough metronome, but one late tap still moves it by a few BPM.
Eight taps: usually settled
Around eight taps the average steadies and the stability meter turns steady. For most songs that is enough.
Sixteen or more: fine-tuned
Tap through a whole phrase for the closest reading. Over 16 beats at 120 BPM, a tap 20 ms late moves the result by less than half a BPM.
Very fast or slow songs: change what you tap
Above about 160 BPM, tap every other beat and press ×2; below 70, tap the eighth notes and press ÷2. Your hand stays in its easy range.
Tap Tempo vs Automatic BPM Detection
Two ways to the same BPM: tap tempo when you can only hear the music, automatic detection when you have the file.
| Tap tempo calculator (this page) | BPM finder (automatic) | |
|---|---|---|
| What it needs | Your ears and a key, a click or a touch | The song as an audio file |
| Streams, radio and live bands | Yes | No |
| Time to a reading | Five to ten seconds of tapping | A few seconds per file |
| Precision | Close, better the longer you tap | Two decimals on a steady beat |
| Half or double time | You choose the beat you tap; ÷2 and ×2 if needed | Can land on either; one click to switch |
| Music with no drums | Works: tap the pulse you feel | Harder: little to lock onto |
| Songs that change tempo | Tap each section as it plays | One reading per file |
| Extras | Metronome and delay times | Click track and beat grid |
BPM to ms: Delay Times at 120 BPM
Every note value at 120 BPM, from the BPM to milliseconds calculator above. Straight = 60,000 ÷ BPM × beats in the note; dotted × 1.5; triplet × 2/3; Hz = 1,000 ÷ ms. Rounded to two decimals.
| Straight | Dotted | Triplet | Hz (straight) | |
|---|---|---|---|---|
| 1/1 (one 4/4 bar) | 2,000 ms | 3,000 ms | 1,333.33 ms | 0.5 Hz |
| 1/2 | 1,000 ms | 1,500 ms | 666.67 ms | 1 Hz |
| 1/4 (one beat) | 500 ms | 750 ms | 333.33 ms | 2 Hz |
| 1/8 | 250 ms | 375 ms | 166.67 ms | 4 Hz |
| 1/16 | 125 ms | 187.5 ms | 83.33 ms | 8 Hz |
| 1/32 | 62.5 ms | 93.75 ms | 41.67 ms | 16 Hz |
| 1/64 | 31.25 ms | 46.88 ms | 20.83 ms | 32 Hz |

Who Uses a Tempo Tapper
Anyone who hears the music before they have the file, or needs the number for an effect.
DJs
Use it as a song tapper for a request playing from a phone or a track on the other deck, and check it sits within a few BPM of what comes next.
Guitarists with delay pedals
Tap the band's tempo, read the dotted-eighth time and dial the pedal in by number when it has no tap switch of its own.
Producers and mix engineers
Get delay and reverb times in ms for a session, and LFO rates in Hz for tremolo, auto-pan and filter movement.
Drummers and bands
Tap a song from a rehearsal recording, then run the metronome at that tempo for practice and count-ins.
VJs and live visuals
Match visual loops to the DJ's tempo; for visuals that react to the sound on their own, run a live audio visualizer or the audio visualizer.
BPM Tapper FAQ
Quick answers about tapping, delay math and what this tool does.
What is a BPM tapper?
A BPM tapper, or tap BPM finder, finds a tempo from your taps instead of from a file. You tap along to the beat and it divides 60,000 by the average gap between taps. People type it many ways (tap BPM, tempo tap, BPM tap finder, tapbpm), and it is the same idea each time. This tap BPM tool works as a tap tempo BPM counter and a tap tempo BPM calculator, with a metronome and delay times built in.
How do I tap tempo accurately?
To tap beats per minute accurately, tap the beat you would clap to, usually the kick or the snare, and keep your hand steady rather than chasing each hit. Tap on the beat for eight beats or more and watch the stability meter. To tap out the BPM of a very fast song, tap every other beat and press ×2 (or D).
How many taps does it need?
A reading appears on the fourth tap, and about eight is usually enough for it to settle. Tapping a whole phrase of 16 beats or more gets the closest result, because one late tap counts for less across a longer span.
Tap tempo or automatic BPM detection: which is more accurate?
With a file and a steady beat, automatic detection is more precise: it measures every beat and reports two decimals. Tapping is the better choice for streams, radio and live bands, for music without drums, and for half-time styles, because you decide which beat counts.
How do I convert BPM to ms?
Divide 60,000 by the BPM to get one beat (a quarter note in 4/4) in milliseconds: 60,000 ÷ 120 = 500 ms. Halve it for an eighth, multiply by 1.5 for a dotted note and by 2/3 for a triplet. To convert BPM to seconds, divide 60 by the BPM. The calculator on this page converts beats per minute to milliseconds for every note value at once, so it works as a BPM to ms calculator, a BPM to milliseconds converter, a BPM millisecond calculator and a BPM converter for Hz.
How do I convert milliseconds to BPM?
Divide 60,000 by the milliseconds: a 500 ms gap is 120 BPM and a 375 ms gap is 160 BPM. So if a delay pedal shows 400 ms for quarter notes, the song is at 150 BPM. Every milliseconds to BPM calculator, milliseconds to BPM converter or ms to BPM converter uses that same formula, and so does this page: type the time into the ms per beat field and the BPM appears, with the metronome and delay table following it.
What delay time should I use at 120 BPM?
A quarter note (500 ms) gives a clear echo on every beat and an eighth (250 ms) a busier one. A dotted eighth (375 ms) makes the galloping repeat guitarists love, and an eighth-note triplet (166.67 ms) a swung shuffle. The delay table above lists every value, straight, dotted and triplet.
What do dotted and triplet mean in the calculator?
A dotted note lasts one and a half times its plain length, so a dotted eighth equals three sixteenths. A triplet fits three notes into the space of two, so each lasts two thirds of the plain length. Both put echoes between the beats, which is why they sound wider than straight delays.
What is the Hz setting for?
Switch the table from ms to Hz to see rates instead of times. Hz is how many times per second something repeats: 1,000 ÷ ms. Use it for effects that run on a rate rather than a time, such as tremolo, auto-pan, a filter wobble or a vibrato LFO. At 120 BPM, quarter notes are 2 Hz and sixteenths 8 Hz.
Can I tap on a phone or with the keyboard?
Yes. On a computer press Space, Enter or T, or click the pad: it works as a BPM clicker, and on each click BPM updates. On a phone or tablet, touch the pad; touch BPM works exactly the same way. There is no small BPM button to hunt for: the whole pad is the BPM pad, from click to BPM in a few seconds.
Does it work with Spotify, YouTube or a live band?
Yes. It is a music tapper, not an audio analyzer, so it works with anything you can hear and never touches the audio. Need a tempo online? Tap for a song on Spotify, a YouTube video, the radio or a band in the room. It is the easy way to tap for beats per minute when there is no file to analyze.
Why did the reading start over?
The count starts over after a pause between taps (2 seconds by default; choose 1.5, 3 or 5), so each new song starts clean. If it resets in the middle of a slow song, set a longer gap, or tap the eighth notes and press ÷2. Esc clears the count by hand.
Can the metronome play in 3/4 or 6/8?
Yes, and 2/4, 5/4 and 7/8 too. Pick the time signature and the metronome accents the first beat of each bar at your tapped tempo; the BPM counts the clicks of that signature. Use 3/4 for waltzes and many ballads, 6/8 for a rolling compound feel, and 4/4 for almost everything else. Keep the tab in front while it plays: browsers slow down background tabs, and the click can stutter there.
Is this BPM tapper free?
Yes: this BPM tapper online is free, with no sign-up and nothing to install. Like any online tapper, it is a tap tempo website that runs in any current browser, on a computer or a phone, and nothing you tap is stored. Need a BPM online? Tap the pad. Tap BPM online as often as you like: the online BPM tap, the metronome and the BPM calculator online cost nothing.
