How to find the BPM of a song
Upload any audio file and the BPM finder analyzes the waveform using onset detection — identifying energy peaks that correspond to individual beats. The built-in beat tracker measures intervals between those peaks and uses a histogram to return the most consistent tempo. If you do not have a file, use the tap tempo section above: tap the button in rhythm and get a live BPM reading in seconds. Wondering “what beat is this” while listening to a track? This tool answers that instantly.
Find BPM from YouTube
The fastest workflow for a YouTube BPM finder: open the video, use a browser extension or site to download the audio as an MP3, then upload it here. The tool detects the tempo in seconds — no extra software needed. To find BPM from YouTube in one step, paste the URL directly into the input field above once the YouTube feature is enabled.
What is BPM and why does it matter?
BPM stands for beats per minute— the universal measure of musical tempo. A higher number means a faster track. Pop and house music typically sits at 120–130 BPM, while hip hop BPM ranges lower, usually between 60–100 BPM. Many 120 BPM rap songs blend hip hop rhythms with a faster, danceable tempo — Miley Cyrus's Party in the USA, for example, runs at 96 BPM. Knowing a song's exact tempo helps DJs beatmatch seamlessly, producers sync loops without drift, and runners choose songs with similar BPM to maintain a steady cadence. BPM is the single metric that keeps everything locked in time.
Using BPM for osu! and rhythm games
In rhythm games like osu!, accurate BPM detection is essential for setting timing points in beatmaps. Upload the song file to run an osu! BPM test before opening the editor, then enter the detected value as your first timing point. Popular osu! tracks like Megalovania (120 BPM) and All8 are known for their precise, consistent tempo — making them ideal for verifying your detection workflow. The tap tempo feature doubles as a manual speed check: tap along with the track and compare the result to the detected value.

Frequently asked questions
What does a BPM finder do?
A BPM finder analyzes an audio file and detects its tempo — the number of beats per minute. SonicLab's BPM finder uses onset detection and histogram-based estimation to return an accurate result with a confidence rating (high, medium, or low). Upload any MP3, WAV, or FLAC file and get results in seconds.
Can I find the BPM of a YouTube video?
Yes. Download the audio from the YouTube video as an MP3 and upload it to the BPM finder. Once the YouTube URL input feature is live, you will be able to paste the link directly and skip the download step entirely.
What BPM are most hip hop songs?
Most hip hop songs fall between 60–100 BPM. Modern trap beats often sit around 140 BPM counted in double-time, while classic boom-bap tracks tend to be 80–95 BPM. Upload any hip hop track to the BPM finder for an exact reading.
How do I find songs with a similar BPM?
After detecting a tempo, search for tracks at the same BPM on Spotify using its tempo filter, or browse a BPM database. DJs use this to build smooth mixes; runners use it to match cadence. Finding songs with similar BPM is one of the most common DJ prep workflows.
What is the BPM of Megalovania?
Megalovania by Toby Fox runs at exactly 120 BPM. It is from the Undertale soundtrack and is one of the most-mapped songs in osu! — its consistent tempo makes it easy to align timing points precisely.
How do I use this tool for osu! beatmapping?
Upload the song file to get the BPM, then enter that value as the timing point in the osu! editor. Use the tap tempo feature to cross-check: tap along with the song and compare the manual reading to the detected result. Consistent agreement between both methods means your timing point is accurate.
What is tap tempo and how does it work?
Tap tempo lets you find the BPM of any song without uploading a file. Tap the button in time with the beat — the tool calculates the average interval between taps and converts it to beats per minute. It works as a manual autotap beat tracker and resets automatically after a 3-second gap.
Is this BPM finder free?
Yes, SonicLab's BPM finder is completely free. No signup, no account, and no limit on how many files you can analyze. All audio processing happens in your browser — your files are never uploaded to any server.
