In
signal analysis, beat detection is using
computer software or
computer hardware
Computer hardware includes the physical parts of a computer, such as the computer case, case, central processing unit (CPU), Random-access memory, random access memory (RAM), Computer monitor, monitor, Computer mouse, mouse, Computer keyboard, ...
to detect the beat of a
musical score. There are many methods available and beat detection is always a tradeoff between accuracy and speed. Beat detectors are common in music visualization software such as some
media player plugins. The
algorithms used may utilize simple statistical models based on
sound energy or may involve sophisticated
comb filter networks or other means. They may be fast enough to run in
real time
Real-time or real time describes various operations in computing or other processes that must guarantee response times within a specified time (deadline), usually a relatively short time. A real-time process is generally one that happens in defined ...
or may be so slow as to only be able to analyze short sections of songs.
