BPM Counter

BPM Counter is a fast and accurate beats per minute detector for MP3 music. It may be helpful for DJs who need to get information about entire music collection quickly and for any kind of remixing/sampling stuff. Don't waste your time for manual tapping, just navigate to any folder with music and BPM Counter will show all compatible audio files (MP3 and WAV) and start BPM detection automatically. A common mistake with other BPM detectors is they may halve or double the actual BPM rate because decoder MP3 files partialy with lower quality. We use high-quality audio decoders from Audio Converter Plus to guarantee balance between performance and accuracy.
