I analyzed several playlists through it, the result is excellent. Honestly, I expected a worse result and now I'm pleasantly surprised. Perhaps the accuracy depends heavily on the musical genre. Only once it turned out twice the value. BPM values of the other 30 tracks are determined correctly.
I agree with Lany. Accuracy of this program is sad. Specially if this program do only this.
Great concept, but it's not accurate enough for me. For instance, I made a wav file and your software reports it as having just over 100 bpm. When I turn that same file into an mp3, the bpm go down to 95. I wrote a song at 135 bpm according to my music program, but when I export that file, your software says it's only 98 bpm. I need more accuracy.
This program is a revelation. I have run it on my entire MP3 collection to find tracks that match my treadmill walking speed. Windows allows you to add a "Beats-per-minute" column to the File Explorer so you can easily sort files after you have run BPM Counter to find the files that you need, in my case about 109-125bpm. Walking or running in time to your favorite music is actually fun and makes the miles zoom by. After losing 20% of my body weight, I'm so happy I found this program!
