Questions
Does BPM Detector upload my song?
No. The file is decoded and analyzed locally in your browser tab. Utilumo does not upload or store the audio.
Why might BPM be half or double?
Tempo algorithms can lock onto a slower pulse or a faster subdivision. The tool shows half-time or double-time options when they are useful.
Is this DJ-grade BPM detection?
No. It is a fast browser estimate. Use low-confidence results as a starting point, especially for live, ambient, or tempo-changing tracks.
Does Utilumo upload my input?
No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
