What Exactly Is BPM?
BPM stands for Beats Per Minute — it measures the tempo or speed of a song. A slow ballad might sit around 60-80 BPM, while a high-energy EDM track could reach 140-180 BPM. Knowing BPM is essential for DJs mixing tracks, producers aligning instrument loops, and dancers matching choreography to the beat.
How to Detect BPM from Any Audio Source

The most accurate method. Upload MP3, WAV, or any audio file directly. The tool analyzes the waveform and detects beats using signal processing algorithms. Results are typically 99%+ accurate.
Method 2: Use Your Microphone
Play any audio source near your device's microphone — YouTube, Spotify, vinyl records, or a live performance. The tool listens and analyzes BPM in real-time. Best for quick checks when you can't download the file.
