liveBPM - Beat Detector is a must-have app for musicians, DJs, and bands who want to keep their tempo on point. This Android app detects music and beats through the microphone and continuously displays the current tempo in beats per minute (BPM). It provides high-quality results while being energy efficient.

With a well-tested beat detection engine, liveBPM can handle most genres and produce accurate results within 0.1 BPM under the right conditions. It works best when the tempo is constant or almost constant, and strong impulses like drums, bass, or guitar define the beat. The time signature should be 4/4, 3/4, or a multiple of either.

liveBPM offers a range of features, including a tempo curve that shows the development of tempo over time, multiple zoom modes to show the last 2, 3, 5, 7, 10, 15, 20, or 30 minutes, and advanced audio spectrum analysis via FFT. It is more accessible and accurate than BPM counters that function through tapping, and it has relatively low battery drain thanks to its high-performance code and efficient algorithms.
