How to change the BPM of an audio file in Logic Pro.mov

[djspoonz]

good vid mate. perfect explanation.

[Kingisland32]

Er, my "Process And Paste" button is grey (i can't click it)

What could my problem be?

[4initialD]

the short clip i have is 92bpm and that's the original bpm. When i go to factory and choose destination say 85bpm i don't hear a difference in the sound clip, it actually doesn't do anything lol

[4initialD]

nvn found a solution

[NicoQuedenbaum]

After I pitched one of my acapellas to a lower tempo, it played with interruptions :-( pls help me :-)

greetings from germany : Nico

[LifevsMusic]

@NicoQuedenbaum das liegt an dem time-stretch algorithmus den logic, jedes andere programm und auch analoge sampler benutzen um das tempo einer datei zu ändern, ohne die tonhöhe zu beeinflussen. der funktioniert so, dass die datei einfach in gaaaanz kleine teile gehackt wird und die dann ein stück auseinander gezogen werden. wenn das orginal tempo und das zieltempo zu weit auseinander liegen werden diese lücken hörbar. faustregel: max 10% abweichung. wikipedia: "time-stretching"

[NicoQuedenbaum]

@LifevsMusic thx :-)

[drewbentham]

Not sure which version of Logic you're using, but its far easier and quicker to add a bpm counter on the track and time stretching it to the tempo you want.

[SeagzUk]

good post, another way of finding out the bpm is go to inserts-metering-bpm counter usally gets it close anyway :P

[ymmijnow]

cool, permanently ruined my wav files.

[LifevsMusic]

@ymmijnow if you open up the sample editor you can choose "save backup copy" (or something similar, my logic is in german - unfortunately .:D) under the "audio data"-menu which is at the top left of our sample editor window. that should save your files. another possibility would be to manually create a copy in your finder window. :)

[marlizjk]

The BPM didn't even change. arrrgh why can't I find the solution what I'm looking for!

[d4funky1]

Thanks for this just what I was looking for

[townwine]

I like to know how to change voice grid cause I lost my voice grid I don't know how to get back can u show me that please!

[TREBLEANDSONIDO]

Hej man, didn't you notice that when the processing in the time and pitch machine was done, the audio file drastically drops in volume? You should check out the waveform at the beginning, fully mastered to 0 db and then afterwards the volumes drops back a hell of a lot ... Any tips on how to get it back to 0 db? Cause there probably will be a peak which reaches the 0 db line and pushes all the other audio downwards ...

[arunco412]

cant i just use a bpm tool to figure out

[arunco412]

y do u chang it back to 110

[arunco412]

what does this exactly do

[cartolano1]

what song is this? sounds like saosin maybe.. but i dig it, what did u end up doing with it? or was it solely for the tutorial?

[christedge]

@cartolano1 It is Dead Poetic and I made a mashup with it. I've got it on my channel

[tionomapali]

thanx man i was looking EXACTLY for this information!

[joeryanisaocelot]

Okay, so you haven't actually changed the BPM of the audio file, this is misleading. You haven't made the audio any faster or any slower, you've just changed the tempo of Logic to fit the audio.

[christedge]

@joeryanisaocelot that isn't true... the only reason I change the tempo of the project is to find the tempo of the track. After I find out the tempo that is when I change the tempo of the audio file in the sample editor

[joeryanisaocelot]

@christedge oh right, I blame my short attention span for that one, sorry dude.

[trepinmusic]

I need some major help. I already know the BPM of my song and when i open it up in the sample editor... I make sure I select all... but in the factory tab the groove and time machine is dimmed and will not let me select it. Why?

[trepinmusic]

@trepinmusic never mind i figured it out! it has to be a uncompressed file.

[sebastianlarsen]

Why dont you use Logic's BPM-counter??? lol

[christedge]

@sebastianlarsen I have found that it takes just as long to do it that way and isn't very accurate

[ultran84]

@christedge +1

[BeastClutch21]

Is Logic Pro only for mac?

[christedge]

@BeastClutch21 Yes

[australiandj]

@TheDragon20000 he said the name the first thing he said! dead poetic

[supermanky]

It seems to me that you're just guessing at everything, and because you're so good at guessing, everything is just matching up. What am I missing?

[christedge]

@supermanky since i don't have every BPM memorized i have to figure it out. This is the best way that I have come up with... do you have a better suggestion?

[australiandj]

@christedge I would suggest you get a copy of a program like traktor, Or virtual dj. (Basically if you use the bpm from that its very accurate for this. If u want a cheaper option then im sure you can get a bpm matcher from somewhere that does just this. Logic really need to address this problem. cubase doesnt have this problem. Hope this helped a little anyway.

[christedge]

@australiandj Thanks

[ElfMagic42]

How are you doing those drags where you chop the song and the first part of the cut disapears?

[christedge]

@TheDragon20000 Paralytic by Dead Poetic. It is kind of the only good song off of Vices, but New Medicines is a very good album

[stavanger88]

Thanks for nothing.

[stavanger88]

Thanks for nothing.

[OggyBeats]

Or you can just insert the bpm detector by inserting it in effects under metering.

[techwrecktrance]

thanks bud

[sarkzbeats]

thank YOUUUUU! :D i've been trying to figure this out for ages :)

[neosouljazz]

i get some distorted sound to audio files after i change the tempo. do you know any way i can fix that?

[christedge]

@neosouljazz I'm not sure what is going on there. It might be the bit rate of the original audio file.

[TechnoCal]

@christedge When you slow down audio files it gets choppy because the bit rate gets lower when you slow a clip down. Speeding up a clip usually doesn't give the distortion because speeding up a clip doesn't need to fill in gaps in the audio of the clip

[blaccstacy]

good stuff

[anchorman1022]

Hey man, great video, it helped me out a lot.

Quick question, I tried this on a track and it worked perfectly, but when I imported the other song (the one that I did not want to change the tempo), i was sped up as well. Is there a way that I can only change the tempo of the one track?

[frenchtouch619]

@anchorman1022 Same here, we need the answeeeeer !! lol

[frenchtouch619]

@anchorman1022 Same here!! I cant figure it out!
