Abstract
A music tempo calculation system includes an amplitude adjuster for receiving an electrical signal of the music and outputting an amplitude-adjusted electrical signal; a detector for receiving said amplitude-adjusted electrical signal and outputting a beat signal when an amplitude of said amplitude-adjusted electrical signal exceeds a threshold value; and a computer for receiving said beat signal and calculating the tempo of the music.
Claims18
System for calculating the tempo of music, comprising:
- an amplitude adjuster for receiving an electrical signal of the music and outputting an amplitude-adjusted electrical signal;
- a detector for receiving said amplitude-adjusted electrical signal and outputting a beat signal when an amplitude of said amplitude-adjusted electrical signal exceeds a threshold value;
- and
- a computer for receiving said beat signal and calculating the tempo of the music;
- and
- wherein:
- said amplitude adjuster including an amplifier for receiving said electrical signal and outputting an amplified electrical signal, and an attenuator for receiving and selectively attenuating said amplified electrical signal and outputting said amplitude-adjusted electrical signal;
- and
- said computer including an amplitude control for sending an amplitude control signal to said attenuator, said amplitude control signal changing attenuation of said amplified electrical signal in one of (1) single steps, and (2) multiple steps.
