I was trying to export the bpm date saved in the virtual dj database to some sort of format i could place on my smartphone in case it would ever come out handy. Now it seems that the bpm value is in some sort of 5digit number and i cannot see any link to the value it presents. Its not binary its not hexadecimal. Does anyone has a clue?

its the distance between two beats but measured not in seconds but in 44100ths of second
(because of 44.1kHz sampling rate)

Is there some sort of formula to easily convert it to BPM??

44100 * 60 / BPM_XML = BPM
44100 is the sampling frequency in samples per second
60 is for 60 seconds (because we are counting beats per minute)
value is the BPM value from the VDJ xml file that shows what's the distance between two beats (measured in samples)
for example
Alcazar - This is the world we live in (extended version) has 21168 in my xml.
BMP = 44100*60/ 21168
BMP = 125
