Nice to have a free app on a Friday. Music Bpm Analyzer is free today, not sure for how long though. Here’s the app’s description:
Provides completely automatic beats-per-minute detection using computational music analysis algorithms. Audio recorded by the iPhone is analyzed in real-time resulting in very high precision bpm results. No tapping is required. This is essential software for professional DJs.
- Fast and high precision analysis
- No tapping required
- The computation is done completely on the device (no connection with a server required)
In addition to determining the bpm of a music track, this app has also been used
- by music bands as a digital metronome to track the tempo while practicing
- to determine the frequency of clock ticks for clock construction and repair
