The BPM readings from Audio Surgeon were comparable to, and as accurate as, the best available technology.

2

The BPM technologies we tested worked well with Rock, Country and Pop music. They were less reliable with Jazz. They were the least accurate with Choral and Orchestral music where there often is no defined pulse.

3

There are times when the bpm reading may be off by 50%. This is due to the fact that the programs are not given the “metrical level”. In other words, they are not told, and have no way of knowing, the time signature for each song, e.g. does the quarter note get 1 count, or the eight or the half. By default these programs typically will display the faster of the BPM rates.

Even when the numerical BPM value being displayed for a particular song is not correct, the program is detecting a musically correct pulse, i.e. in time with the music. For example Audio Surgeon calculates the BPM of the song “Hotel California” to be 148. The true value from the sheet music is 74, or ½ that value. In the bigger picture both values accurately depict the pulse of the song.

Below is a comparison table of BPM data comparing Audio Surgeon to its competitors across a range of different musical genres.
