Instantly measure rhythm by tapping or automatically analyze audio files.
A free, browser-based tool for musicians and editors.
Tap 4 or more times to the beat
Identify the BPM of instrumental tracks to set the correct grid in your DAW or calculate delay times for mixing.
Essential for syncing video cuts to music. Knowing the BPM helps you edit perfectly to the beat.
Organize songs with similar tempos for smooth transitions in DJ sets or running playlists.
Setting the correct BPM (Tempo) in your DAW project is crucial for recording and mixing. If the tempo setting doesn't match the audio file, editing (copy-paste) becomes difficult, and time-based effects like Delay and Reverb may sound off.
We recommend measuring the BPM of any instrumental track before starting your project.
Italian terms like "Allegro" or "Andante" on sheet music indicate the mood and speed. Here are their approximate BPM equivalents:
| Term | Meaning | Approx. BPM |
|---|---|---|
| Largo | Broadly, slowly | 40 - 60 |
| Adagio | Slowly, with expression | 66 - 76 |
| Andante | At a walking pace | 76 - 108 |
| Moderato | Moderately | 108 - 120 |
| Allegro | Fast, quickly | 120 - 168 |
| Presto | Very fast | 168 - 200 |
Each music genre has a typical tempo range. Use this as a reference for production or DJing.
| Genre | BPM Range |
|---|---|
| R&B / Soul / Ballad | 60 - 90 |
| Hip Hop / Reggae | 85 - 100 |
| Pop / Rock | 90 - 135 |
| House / Disco | 120 - 130 |
| Techno / Trance | 125 - 140 |
| Dubstep | 140 (Half-time 70) |
| Hard Rock / Metal | 140 - 190 |
| Drum'n'Bass | 170 - 175 |
Double Time means feeling the rhythm twice as fast. For example, a slow ballad at 70 BPM might be interpreted as 140 BPM depending on the drum pattern.
Half Time is the opposite, feeling the rhythm at half speed. Dubstep often has a drum pattern at 70 BPM but is produced at 140 BPM.
This tool displays "Maybe: Double Time / Half Time" to help with these interpretations.
This tool assumes a constant tempo throughout the track. It may not provide accurate results for:
- Songs with Tempo Changes: Tracks that speed up or slow down (e.g., Live recordings) may show an average value.
- Odd Time Signatures: Complex rhythms (like 5/4 or 7/8 time) might confuse the automatic detection algorithm. In these cases, please use the "Tap Mode".
Tap along to the beat, or let the analyzer estimate the tempo of an audio file.
File analysis works best in Google Chrome or Microsoft Edge. Your audio is never uploaded, so you can safely analyze unreleased tracks and demos.
Once you know the tempo, you can sync delay, reverb pre-delay, and LFO effects to it. One beat (a quarter note) lasts 60,000 ÷ BPM milliseconds.
| BPM | Quarter note | Eighth note | Dotted eighth | One 4/4 bar |
|---|---|---|---|---|
| 70 | 857 ms | 429 ms | 643 ms | 3.43 s |
| 90 | 667 ms | 333 ms | 500 ms | 2.67 s |
| 100 | 600 ms | 300 ms | 450 ms | 2.40 s |
| 120 | 500 ms | 250 ms | 375 ms | 2.00 s |
| 128 | 469 ms | 234 ms | 352 ms | 1.88 s |
| 140 | 429 ms | 214 ms | 321 ms | 1.71 s |
| 174 | 345 ms | 172 ms | 259 ms | 1.38 s |
BPM stands for beats per minute. It measures a song's tempo: 60 BPM is one beat per second, and 120 BPM is two beats per second.
Tap Mode is as accurate as your timing, and it averages your last 8 taps to smooth out small errors. File Analysis gives an estimate that works well for songs with a steady beat, but quiet intros, live recordings, and complex rhythms can reduce accuracy.
Many songs can be felt at two tempos. A hip-hop track at 85 BPM can also be counted as 170 BPM, and dubstep at 140 BPM often feels like 70. Pick whichever matches how you count the beat.
Safari sometimes cannot decode audio files for analysis. Use Google Chrome or Microsoft Edge on a computer, or use Tap Mode, which works in every browser.
You can analyze MP3, WAV, and M4A files. To get audio from a video first, or to change a file's format, use the Audio Converter.
Yes. Use the Audio Speed Changer to speed up or slow down a track, or the Pitch Changer to change the key.
