lol

@p2 , what it does it calculate the exact pitch i will have to set any tune to, on the dj deck

this is calculated to the nearest 0.02% and to the nearest 0.05% (for +/-6% and +/-10% pitch)

Interesting program. Now if only MSD8x was CE-compatible, so that MP3 or WAV BPM could be detected by reading parts of the audio data located on an USB stick

working out the bpm of a track isn't a trivial task, in fact my Pioneer decks (XDJ700) don't even do it that well. in the case of my program you have to know the bpm of each track in advance, exactly, prior to building the app

True. I saw very few apps that did this. Mixmeister Pro could detect BPM but I forgot what I used beforehand. On a calc it would have to only read a small part of the song (of the user choice) else it would be so slow to detect the BPM.

There is a manual solution to the problem which can get the exact BPM but it involves setting points on the positions on kick drums..... I developed a program to help me do it years ago.....



lol oh by the way in case you are thinking the interfrace looks a bit complicated for such a task, this program was used to create beatmaps for records which had been recorded using belt drive record decks (which, as the belt can slip, produce a non-fixed speed output with wow/flutter)
