Tool usage guide
The Audio BPM Detector calculates the beats per minute (BPM) of music tracks by analyzing audio segments. It downmixes audio to mono, examines a specified window, and uses beat tracking to estimate tempo, providing results in JSON format.
Background
A DJ is preparing a set and needs to know the BPM of several tracks to ensure smooth beatmatching.
Problem
Manually tapping BPM is slow and prone to errors, risking poor transitions.
How to use
Upload each audio file and use the default analysis to get instant BPM readings.
Outcome
The tool returns the BPM for each track, allowing the DJ to sort and mix songs effectively.
Background
A producer is remixing a song and must match the original track's tempo in their project.
Problem
Without precise BPM, aligning beats in the software is difficult and time-consuming.
How to use
Upload the original audio file and set the analysis seconds to cover a key section, such as the chorus.
