The way I see it, time is the constant, so if the BPMinute is exactly 4x the RPMinute, then there should be a beat at exactly every quarter rotation. 9)Ħ0 seconds / 133 ⅓ beats = 1 beat every. The target of 180 degrees rotation / degrees per second (200) =. The target of 90 degrees rotation / degrees per second (200) =. If you come up with something different, please share your math!ģ3 ⅓ Revolutions Per Minute = 12ooo degrees of rotation per minuteġ2000 degrees / 60 seconds = 200 degrees per second R1N Recording Studio, post: 441200, member: 49991 wrote: Great, thanks. The OP got their answer straight-away, so I don't think they're coming back to revisit the topic. 45 seconds, which I figure is how long it takes the disc to turn exactly 90˚ - regardless of the constantly shrinking diameter the stylus follows as its being played.Īnybody else want to play, or school me? I'm stuck, and trying to see what I'm probably missing.ĭonnyThompson, sorry for the tangent. I'm figuring at 133 1/3 BPM there's a beat every. If everything were perfectly accurate, and you threw a 4/4 alternating kick & snare beat on a 33 1/3 LP, with a BPM of exactly 133 1/3 wouldn't that put the 1 (kick) of every measure at 0˚, the 2 (snare) at 90˚, the 3 (kick) at 180˚, and the 4 at 270˚ ? And since the RPMs are constant, would that pattern hold over the radius of the entire disc? If the disc cutting facility is doing the mastering, then you need to contact them and find out exactly what they need.ĭvdhawk, post: 441153, member: 36047 wrote: But the OP did get me thinking, because I'm just a fool for this kind of mental exercise, (as opposed to actual, physical exercise)…. You may want to contact a mastering engineer who specializes in prepping audio for vinyl. Mixing for vinyl isn't any different than mixing for digital, but Mastering audio for vinyl differs quite a bit from that of mastering for CD or digital streaming. You should contact the disc manufacturer and ask them what they want in regard to the above.Īs a final note, and no offense intended, you sound like you may be in over your head with this.

It means that the album rotates 33.3 times per minute. Please help me to understand this better.ģ3 1/3 is the speed at which the disc (LP album) rotates on the turntable. So, can anyone please explain me what does "33 1/3 rpm" actuallly mean? If I'm told to give audio materials for cutting in "33 1/3" (I'm recording in Ableton) does that mean the audio should be in 133 bpm or something else? I'm a completely vinyl beginner and I'm trying to find on the web some answers to my question but I can't find anything that helps me to understand it completely. ![]()
