Is there a formula for figuring out the bpm of a record when dropped froom 45 to 33 rpm? for instance, I have a record that's 140bpm when spun at 45 rpm, and I want to know how many bpm it will be at 33rpm |

(33.3/45)*bpm? |

37.4 BPM difference then. |

It's not so simple. We're talking of BPM, i.e. beats per minute, or beats in 60 seconds, so its' x/60 - and x is 140 here, so 140/60=7/3. Secondly, you have to take roundness into consideration, so think circles: 2*pi*45*360, so that's Rounds, and that per minute is (2*pi*45*360)/60=2*pi*45*60. Finally, to compare, you have to take the equation (2*pi*45*60)/(7/3)=(2*pi*33*60)/(x/60), where X marks the BPM at 33 RPM! Trust me on this one. |

Don't talk maths to me. I haven't got time for complex equations. |

i vote for 99'3 BPM. |

What's required here is a relative velocity impedance analysis fulcrum redundancy invertor. I used to have one but I gave it to Oxfam. |

|
|
well, wouldnt it be correct making simply: 140/45 * 33? |
||||||||
|
|

|
|
boxbob dont what the fuck hes talking about. horsey was right. |
||||||||
|
|
|||||||||
| |||||||||
|
|
45 is to 33 as 140 is to X 33/45 = X/140 so... 45X = 33*140 then divide by 45 |

yeaah, wait, that's obvious, but it was something else i forgot... something about pitch. i have a track i want to be 114 bpm, but i want to render it at a higher bpm first and then slow it down to 114 by pitching it down... to simulate going from 45 to 33; i don't have a dub cutter i need to do this in acid or somethingg... trying to figure out by what percentage that needs to be. |

12/45=26.67%(-), though I'm not sure if that's correct. Do you want the original in abnormally high pitch, and then pitch it down to normal, or to have it end up sounding abnormally low? What is the original BPM? It should be roughly 155.5 BPM to simulate 45 RPM. |

i want it to end up sounding abnormally low, at 114 bpm |

hmm, i tried it. didn't work very well of course but it sounds weird so i like it anyway. thanks |

I've found something. It might not help you at all but: If you play a 33 record at 45, pitching it down (while affecting the speed) by: -5 semitones and -26.1 cents will get it back to 33. |

wow, thats probably worth knowing. maths is fun if it involves music. |
