I have a formula that i would like to use with mp3 tag, but i can't seem to get it to work..
I am a DJ and keep my files tagged nicely with mp3 tag and it does a brill job.. what i want to do tho is to calculate a percentage increase/decrease from a bpm field (handy when mixing)..
the formula in excel is (130-%bpm%)/%bpm% then changed to a percentage (*100) (i use mix meister bpm analyser to calculate the bpm then this will tell me the percentage i have to increase the track to mix at 130bpm - lazy i am !)
i can't get this to work in mp3 tag as i think it rounds numbers or removes decimal point
i want it to create a new field or place it in the comment field as something like +1.55%
anyone help pls ?
