Detect the beats per minute (BPM) of any audio file online free. Tap along to find the tempo of any song, or let the analyzer estimate it automatically from the audio.
Matching music tempos for DJ sets, workout playlists, dance choreography, or production remixing requires knowing the exact BPM. Counting beats manually takes 30–60 seconds per song and introduces error - a BPM detector produces the result immediately.
Upload an audio file and detect its BPM (beats per minute) - the tempo measurement used in music production, DJing, and dance. The analyzer finds the dominant beat frequency in the audio.
Find the BPM of a song before adding it to a DJ set, match workout playlist songs to a target beats-per-minute range, verify the tempo of a track before remixing or sampling, match music BPM to video frame rate for synchronized editing, identify tempo for dance choreography planning, check BPM consistency across a curated playlist, and find music within a target BPM range for meditation or focus playlists.
The most common question is about detection accuracy. BPM detection is most accurate for music with a clear, consistent beat - electronic music, pop, hip-hop. It is less reliable for ambient, classical, or music with complex rhythmic patterns, tempo changes, or no percussion. For accurate results, use a clear portion of the track where the beat is most prominent.

Common questions about this tool and how to use it.
BPM stands for Beats Per Minute - the number of rhythmic beats that occur in one minute. It is the standard measure of musical tempo. 60 BPM = one beat per second. 120 BPM = two beats per second (a common dance tempo). Slow ballads: 60–80 BPM. Walking pace: ~100 BPM. Pop and dance music: 110–130 BPM. House music: 120–130 BPM. Drum and bass: 160–180 BPM. Techno: 130–150 BPM. The BPM determines the overall feel and energy of a track.
BPM detection is highly accurate for music with a clear, consistent beat - electronic music, hip-hop, pop with a drum track. Accuracy decreases for: music with tempo variations (live recordings, expressive classical), complex polyrhythmic music, ambient music without percussion, very slow or sparse tempos, and recordings with significant background noise. For straightforward dance and pop music, modern BPM detection is typically accurate to within ±1 BPM.
BPM detectors analyze beat patterns and can interpret the half-beat or double-beat as the fundamental tempo. A 140 BPM drum and bass track might be detected as 70 BPM (half-time feel). A slow 70 BPM track might be detected as 140 BPM if the detector finds a double-time pattern. This is called tempo octave error. If the detected BPM seems wrong, check if doubling or halving the result gives the tempo you know the track to be.
Optimal workout music BPM depends on the activity: Walking: 115–120 BPM. Jogging: 120–140 BPM. Running: 147–160 BPM. Cycling (moderate): 125–140 BPM. High-intensity interval training: 150–180 BPM. Yoga/stretching: 60–90 BPM. Research suggests music tempo matching movement cadence can improve endurance and reduce perceived effort by 10–15%. Many workout playlist curators specifically select tracks within BPM ranges for this reason.
DJs use BPM to match the tempo of two tracks before mixing them together - a technique called beatmatching. Tracks with the same or close BPM can be blended without rhythmic clashing. Manual beatmatching: adjusting the playback speed of one track (using pitch faders on CDJs or turntables) to match the other. Modern DJ software (Serato, Traktor, Rekordbox) detects and displays BPM automatically and can sync tracks electronically. Knowing the BPM of tracks in advance allows planning compatible transitions.
