BPM Counter

About BPM Counter

How to use BPM Counter

1. If you have the audio, drag and drop an MP3, WAV, M4A, or OGG file onto the area at the top — or click to choose one. Analysis runs in your browser and the file is never sent anywhere.
2. The detected BPM appears in large type along with a confidence reading. When confidence is low the track has an unclear pulse, so cross-check it against the tap counter below.
3. If the tempo feels half or double what you expected, press one of the candidate buttons to swap it into the main display. Dance tracks are often the doubled value; ballads are often the halved one.
4. With no audio file at hand, play the song and click the TAP button or strike the spacebar — or any other key — in time with the beat. Press Esc to reset at any point.
5. The number settles after about four taps. The higher the tap consistency meter reads, the more you can trust the value. A single mistimed tap is excluded automatically, so there is no need to start over.
6. Press the button that sends the BPM to the metronome and table, then play it back over the song. Choose 4/4, 3/4, or 6/8 and confirm by ear that the tempo really lines up.
7. The delay-time table at the bottom lists note lengths in milliseconds at that BPM. Copy them and paste the values straight into a delay or a reverb pre-delay in your DAW.

Benefits of BPM Counter

• [Measure from a file or by tapping] One drop for automatic detection when you have the audio, tap tempo when you do not. Use tapping for jazz and acoustic material where automated analysis struggles, and the file path for tracks with a clear pulse — both results sit side by side on the same screen.
• [Mistimed taps removed, no guesswork left] A missed tap is filtered out by a median-based rule before averaging, so a slip mid-count does not force a restart. Readings show one decimal place and tap scatter appears as a consistency meter, so you can tell numerically whether to trust the value. Automatic detection carries its own confidence reading.
• [Put the tempo to work immediately] Send the measurement to the built-in metronome and play it in 4/4, 3/4, or 6/8 over the track to confirm the tempo by ear. A linked delay-time table gives straight, dotted, and triplet millisecond values ready to type into a DAW — no need to open another site after finding the BPM.
• [Zero network traffic, entirely in the browser] Unlike services that upload your audio for server-side analysis, every step runs locally. In a venue with poor reception or on a phone in airplane mode, the page keeps working with no waiting.
