Speeding up a song?

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
 
Hmm, I don't know about reaper, but I know Protools can do this with the 'elastic audio' function.
There is a limit on how far you can go without noticeable artefacts, of course, but if I can help, just let me know.

Thanx a lot Steen. Much appreciated.

I'll wait for a few responses and see what the general consensus is, and maybe I'll end up sending you a track if you feel like seeing if you can help me out.

Thanx brother. :cool:
 
Are you looking to speed up the whole song or parts of it ?

Those time stretch and condense functions are good for this but only to a limited extent. I once had a drum mix that I'd pared down to a stereo pair but I thought the tempo was too fast so I thought I'd stretch it to slow it down. It was so weird. I really stretched it and all the various components were flying all over the stereo spectrum. It was pretty psychedelic on the snare, toms, cymbals and hat but it was painful with the kick. It was jumping to every pan position at random. After, I stretched each track individually then remixed. It was much better.

The whole song. It's at something like 90bpm, but drags a bit in my opinion. I want to bring it up to maybe 92 or 93bpm. That's just enough, but it still seems to be too much for REAPER, unless I'm doing something wrong, which I doubt only because it's a pretty straight-forward function.

I've tried it on a "mastered" mix, ans un-"mastered" mix and also the individual tracks of the song. Always screws up somehow.

I use a small program called "Riffmaster" you can speed up or slow down without changing the pitch.
You can download a free trial here: RiffMaster Pro : Slow down music, & learn your favourites easily!

Not necesarily design for your need but will take care of it....

Thanx a lot. I'll download it right now. Are you sure it speeds up, though. They keep talking about slowling down, but no mention of speeding up. I'll find out in a few minutes, I guess. :)
 
The Riffmaster actually worked better than the speed/preserve pitch function in REAPER. But it still warbled a few things out even at a slight increase in tempo.

Funny thig is, it seemed to do the opposite of what REAPER does. REAPER warbles the stuff in the middle (kik, snare, etc...), but Riffmaster warbled the stuff panned outside (2 guitars, etc..) while keeping the middle pretty much intact.

Now, if only I can combine the 2. :D
 
Ha. Funny that.
It seems there are different algorithms aimed at preserving different types of audio.
I see settings for monophonic, polyphonic, rhythmic, etc.

I just tested out PT with a Bowie track and safely got about 7 or 8 bpm out of it.

Cool! If you have the time, later tonight I can send you a 24 bit wave file of the tune. I probably need 3bpm at the most.
 
Yeah man, that's fine.
I'm guessing the higher the sample rate, the better?
 
You know, I just went and checked, and REAPER says my Project Sample Rate is 44110. Is that normal, or should I be up at 48k or whatever? I ca never get my head around sample rates when I read people talking about them. :eek:
 
Hmm.
The main options are usually 44,100, 48,000, 88,200, 96,000 and 192,000.

44.1's fine. A lot of people work at 48. I don't think I'd worry about it though.
 
Nah, it's not a frequency reference in that way. It's the frequency of samples taken per second.
I'm sure it's a flawed analogy (and i don't really want to know why :p ), but think of it as FPS with video.

I hoping I'm not perpetuating mythology, but if reaper lets you bounce out at higher rates, do that.
If not, don't worry about it.
 
I'm pretty sure it goes up to 96k. But I'm pretty sure that's not necessary, though I couldn't tell you why exactly.
