Sharpen your sense of time! liveBPM is the new tempo reference for drummers, bands and DJs. It detects music and beats via the microphone and continuously displays the current tempo in beats per minute (BPM). This beat detection used is state-of-the-art and delivers high-quality results. You are welcome to check out the time-limited demo version before buying the full version. Using it as a musician:- Use it as an objective tempo reference like a metronome- It actually has several advantages over a metronome:-- You are not tied to a click, giving you more flexibility-- Helps you use tempo changes to enhance your musical expression-- With blind tests, it can massively improve your timing confidence, which is especially important if you are in a tempo leading role (e.g. drummer)- Discover how/whether your favorite artists use tempo changes- Recommended for drum schools and the like- Measure and improve your time-keeping skills- Identify slowdowns and speedups while practicing your instrument- Always be in control of the tempo during your live gigs and rehearsals This is a tool designed for professional use:- Well-tested beat detection engine guarantees trustworthiness- Can handle most genres. Produces the best results under the following conditions:-- The tempo is constant or almost constant-- Strong impulses are defining the beat (drums, accentuated rhythm instruments like bass/guitar etc.)-- Time signature is 3/4, 4/4 or a multiple of either of these- If the music meets these conditions liveBPM will produce results accurate to within 0.1 BPM - Outside of these conditions results can become noisy Further features:- Five-minute BPM graph shows the development of tempo over time (full version)- Advanced audio spectrum analysis via FFT (check FrequenSee)- More accessible and usually more accurate than BPM counters that function through tapping- Relatively low battery drain thanks to high performance native code and efficient algorithms-- Should run for hours with a full charge (4% CPU usage on a Galaxy S2) Note:- You can check and improve the detection by clapping loud to the beat. Also, results can be improved by plugging in a suitable external microphone- Only available for ARMv7+ devices (floating point hardware) with OpenGL ES 2.0 support Feel free to share your experience.
