BPM Analyzer is a small application that allows you to find out, as its name suggests, the number of beats per minute of a song.
The program functions very simply: you only have to download the music file that you want to analyze it will have, in under a minute, a list of the results.
BPM Analyzer as a tool is more interesting than useful that perhaps could be more useful to those who are involved in the music world, but not really for the common user.
