What Does an Automatic BPM Detector Measure?
An automatic BPM detector analyzes the rhythm in an uploaded audio file and estimates its tempo in beats per minute. Unlike tap tempo, you do not need to click along with the beat. Use the result to compare songs, match loops, plan transitions, or time edits before opening a full DAW.
Detect Song Tempo Automatically
Upload local audio and let the browser estimate its BPM without manual tapping, a DAW, or a desktop plugin.
Read BPM First
See tempo as the primary result, with detected key and Camelot notation available as supporting mix references.
Compare Track Speed
Check several songs in one table to find tempo gaps before building a DJ transition, playlist, remix, or edit.
Analyze Several Files
Queue up to 5 audio files at once so demos, references, loops, and edits can be checked in one pass.
Review Music Feel
Use energy, danceability, and happiness scores as secondary context for how each track may feel in a set or edit.
Keep Analysis Browser-Based
Run tempo analysis in your browser for quick checks before organizing files or moving them into production software.
How to Detect BPM from Audio
Upload local audio and let the BPM detector analyze each file automatically.
Upload audio
Choose up to 5 audio files from your device or drag them into the upload area.
Wait for analysis
Each file is processed sequentially, and its row updates as soon as the result is ready.
Use the BPM result
Start with the BPM column, then use key, Camelot notation, energy, danceability, and happiness as supporting context.
Automatic BPM Detection for Tempo-Based Decisions
Use the BPM detector when tempo is the decision you need first. The result table keeps BPM prominent while key, Camelot notation, and music-feel metrics provide secondary context.
Match Song Tempos Before a Transition
Compare BPM values before placing two songs next to each other. Smaller tempo gaps can make beatmatching and transition planning easier.
