Question On BPM

| Alrite.. when I wanna know the bpm of my record I count the beats for 10 seconds and multiply it by 6.. say I get 130 BPM for the track playin out and the incomming tracks BPM I calculated to be 125 BPM. My question here is.. is there any math behind knowing how much % to slide the pitch like 2% or 3% etc.? |

no seriously its hardly possible to 'count' the BPM |

| No maths involved I'm afraid - use your ears... |

| If you don't wanna match using your ears, you need to find a different hobby. |

i created a little formula (back when i used to mix tracks together with cool edit for a laugh) to discover the bpm of a track without a bpm counter or anything, divide 960 by the exact time it takes for 16 beats to occur (usually around 6-7 seconds) and the result is your bpm. obviously accuracy depends on the accuracy of your timings...
if you want to get your calculator out and work out how much percent you need to move it up/down then all it takes is multiplying with decimals, i.e. to increase by 5% you multiply by 1.05, to reduce by 5% multiply by 0.95 (remember, if you multiply by 1.05, then reduce it by 5% by multiplying by 0.95, it will not get you back to where you started. reverse the equation i.e. if you multiplied by 1.05, divide by 1.05)
moving the pitch fader is a load quicker though............. :p |

I can just picture it, records running out because jocks are fiddling with calculators.
Seriously, it is possible to work it out with a formula, but why?- i can pitch accurately in a few seconds at most using the ears and years of practice.
With a formula it would never be spot on, as the fader is completely analogue and you would still have to correct it slightly |

| IMO this is totally overcomplicating the whole process. Use your ears and you'll do just fine. Unless of course your totally beattarded in which case you can try to use math to save yourself. Seriously, people have been doing this for years without calculators and formulas and have been doing just fine at it. I'm sure that with some practice you can do the same. |

Possible, yes. Also utterly pointless.
To use your example, if you've got both decks set at 0%, then you need to raise the incoming by approximately 3.3% (3.3% will equal approximately 4.9 bpm difference). Oh wait, most pitchfaders aren't labelled accurately in units that small... |

Most pitch faders aren't calibrated the same either which creates even more problems. |

To answer the question yes you can, though with the way you are BPMing your records you're only going to get multiples of 6 which is extremely inaccurate.
I BPM all my records using my mixer and then when you mix you instantly have a rough guide as to where the Pitch needs to be. As has been pointed out, the ability to beatmatch solely using your ears is far more important as having the BPM of your records only gives you a rough guide. Also, if you play a versus set against someone and their records aren't BPM'd then you're going to be in the poo. |
