AudioRetoucher can detect the BPM values of loaded music. Detector ignore all active effects like "Tempo" or "Speed" and detect values only for original file. If you wish to calculate BPM of multiple audio files at once then you can use our free BPM calculator.
Detector is able to analyze music at a varying pace. To do this, it determines the change in tempo and splits the audio composition into separate segments with the same tempo. At the end of processing, it chooses the BPM value that has the longest duration. In this way it manages to avoid the troubles with songs that have slow introductions.
The range of values returned by the detector is from 50 to 250 BPM. Note that the BPM detection algorithm cannot provide 100% accuracy, so it returns zero values for very short songs or songs with long silent pauses.
