Speeding up a song?

  • Thread starter Thread starter RAMI

44.1 is the norm for recorded audio. 48 is what video recorders and apps use to handle the audio. (Don't ask me why--they just grew up around two different standards.) So audio programs include the 48 in case you're working with audio from a video project.

I use it a lot. I'll export the audio that I recorded with a video (the speaking or whatever) and do my tweaks in Cubase (just cause that's more natural for working with sound for me). I'll do the whole session in 48 and it drops right back into place in my video software.
 
To be honest, I'm not even sure that bouncing higher than the session rate yields any benefit.
Go about your business! ;)

Any way of speeding a song up, preserving the pitch, but not getting weird artifacts? I've tried it with a finished mix and also on individual tracks. I always get weird stuff happening to the kik especially, but pretty much everything goes a bit weird.

I'm not trying to speed it up by much at all. I'm using REAPER by the way.

Thanx

I've never had to do that, but I read an article by a film audio guy one time where he sped it up (getting the higher pitch) and then he used a pitch-shift tool to get it back to the original pitch. I'm sure there's an easier way though :D
 
If you are using Pro Tools, its called elastic audio. Use polyphonic on most samples, rhythmic on drums and monophonic only if its a singular instrument. Polyphonic works the best for me. If you go athomemusicproduction.com/2013/06/04/how-to-sample-music there is good information on how to sample, and how you can speed things up and slow them down with elastic audio.
 
Thanx man.

So, what do you think about this whole Falkland Islands thing?

During the actual war, there were more people living on the road next to mine than on the whole Falklands. People died for a rock full of sheep out in the Atlantic.

I did this on a vocal just the other day. Slowed it down to half-speed and then used ReaPitch to shift it back up an octave. This was not a whole mix, just the scratch vocal, and it's pretty extreme to go a full octave. It sounds a little slurred because the consonants are stretched, but I was amazed at how natural it sounded. Didn't mess with any of the "formant" sliders or anything, just the one main pitch slider up 12 semitones. You'll have to do the math, or use your ears, to figure out how far to pitch it.

That said, I find myself wondering why it's so important to preserve the pitch. Are you going to need to play along with it later, or add more tracks, or something? 2 bpm shouldn't make enough difference to be noticeable pitch-wise. It was pretty common practice in the analog days to just twist the vari-speed control until it felt right, or fit where you needed it. Reaper's playback speed adjustment (without pitch preservation) is absolutely awesome. Especially since it can be applied to individual tracks, it's one of my favorite features.
 
I think RAMI's point was that he asked the question a year ago !

Hehe....Yeah, that's cool though. They're allowed to discuss.

3 monks that were only allowed to talk once a year were having dinner. One monk gets up and says "I find the soup too salty".

A year later, they're having dinner again and the second monk says "I find the soup not salty enough".

The next year, at dinner, the third monk gets up and says "I'm tired of all this bickering".

Yeah it's pretty neat stuff. The example I saw in film was a child actor who's voice had deepened while they were shooting a movie. They did half his movie dialogue that way!
 
There's gold in them thar old threads...

Reapitch.... must play with it now. Never even knew it was there...;)
 
Not sure if this is still relevant, but Ableton does this rather easily without any pitch changes. Since it has a EDM focus, you can load up a song, and then change the BPM without much difficulty. In session view, you can even load up multiple songs and set their BPM to match another song. For example, I was just playing around with different tunes to create a dance mix, I wanted to keep the songs around 120. Just put the song into the clip, gave it the target BPM and kept everything on beat.

You could try LE if you ever have a need in the future. Ableton has some good manipulation functions.
