Frequently asked questions
How do I find the BPM of a song online?
Upload your audio file to this tool. It analyzes the waveform using onset detection and autocorrelation to find the tempo automatically. Results appear in seconds. No signup, no upload to server.
How accurate is the BPM detection?
Very accurate for songs with a clear beat (pop, electronic, hip-hop, rock). For complex or irregular tempos (jazz, classical, ambient), use the tap-to-beat mode to manually find the BPM by tapping along.
What is tap-to-beat mode?
Click the tap button in time with the beat of your music. After several taps, the tool calculates the average BPM from your tap intervals. This works for any music, even tracks without a strong rhythmic pattern.
Can I detect BPM of an MP3 or WAV file?
Yes. The tool accepts MP3, WAV, OGG, FLAC, M4A, AAC, and any other format your browser can decode. The file is processed locally and never uploaded.
Why would I need to know the BPM of a song?
DJs match tempos for smooth transitions. Producers set project tempos. Musicians practice at specific speeds. Runners pick songs at their target pace (e.g., 160-180 BPM for running). Video editors sync cuts to beats.
Does this work on my phone?
Yes. The BPM detector works in any modern mobile browser. No app needed. Upload or record audio directly.
Can I detect BPM without uploading a file?
Yes. Use the tap-to-beat mode to manually tap along to any audio playing on your device or in the room. No file upload required for manual detection.
Can I use the tap mode without a file upload?
Yes. Play any audio from any source (Spotify, YouTube, your speakers) and tap the Tap button in time with the beat. After 6 to 8 taps the tool shows a stable BPM reading from your average tap intervals. No file needed.
How do I find the BPM of a song without downloading an app?
Open this page, drop your audio file in, and the BPM appears in seconds. No app to install, no account to create. Works in any browser on any device. If you do not have the file, use tap-to-beat mode: play the song from any source and tap along.
What BPM should I look for when building a running playlist?
Match the BPM to your cadence. Easy jog: 140-150 BPM. Steady run: 160-170 BPM. Fast tempo run: 170-185 BPM. Upload your songs here to find which ones fit your target pace, then build your playlist around them.
