Creating an electronic metronome interface is simple, but TrueMetronome does not cut corners: it recreates the look and feel of a real mechanical metronome; every mark on the scale is labeled with a tempo mark, the deviation angle of the pendulum depends on the tempo, and the tempo is selected by dragging the weight.
Moreover, the identical samples playing at the same frequency can drive any man crazy! TrueMetronome solves this problem thoroughly: all sounds are recorded from real metronomes, a beat does not affect the gradual decay of its predecessors, and each beat's sound is a little different from the others.
Serious musicians prefer a natural sound filled with overtones, but all metronome apps play short synthetic samples (so that the first sound stops completely before the next begins).
Almost all metronome apps boast about their accuracy, but users with sensitive hearing notice inaccurate beats all the time.
Despite the failure of other apps, perfect time is possible for TrueMetronome: its unique engine creates perfect beats with ABSOLUTE ZERO error.
