Dance Metronome/BPM

This month, HotPaw Productions introduced a new iOS app, Dance Metronome/BPM now available from Apple's iTunes App Store. This app has both a tap BPM (beats per minute) meter and a very accurate metronome. The BPM meter is designed for ballroom dancers, as it indicates whether a particular tempo is within strict tempo range. All the International Standard, Latin and American Style Smooth and Rhythm dance tempos are included. The metronome in the app can play beats, on time, to sub-millisecond accuracy. (Given an audio sample rate of 44100Hz, there are 44 samples per millisecond, and the Dance Metronome/BPM app calculates the nearest exact sample to start playing each on-time beat.)
