O.K.....I have a song completely recorded, spliced, diced, mixed, finished. Except for one little (BIG) thing. It's too slow. Not much, just a few bpm. Is there any way to realistically speed it up without changing the pitch (short of redoing the entire frickin' thing)? :help: :?:

Nothing will give as good results, afaik, as doing it again. :(

you could try time-stretching it in a decent audio editor (I don't think Tracktion's stretch will cut it) but its not something I'd ever do to one of my masters!

You might get better results by exporting each track to be stretched individually, as you could then optimise the settings for each track, and the artifacts may be less obvious if they don't affect the whole track.. but if it was me I would rather spend that time redoing it, as there's a good chance it will still sound crap!

Is it essential that the pitch doesn't change? I had a similar problem recently which I solved by pitching the track up a semi-tone (in Tracktion, select clip -> change pitch speed).

I ended up re-mixing it anyway for other reasons, but I kept the key change!

Thanks for the reply. I'll give that a try but I guess I'm resigned to doing it again. Thought I might as well ask in case by some off chance some genius recently released an app I didn't know about that would do it.

Thanks again,

if it's just a couple of bpm, and you are increasing not decreasing BPM, depending on teh type of material you might get accpetable results through something like recycle.

I've gotta echo plat's view on doing it again, but recycle or similar might just get you out of trouble...

Platinum ears, YOU ARE THE MAN! :D :D

The change pitch/speed worked for my current purposes which is demo and OMD posting. I definately wouldn't do this to a master, Funny, as I started to go up the whole song fell apart then came right back together around the 1.015 factor. I was able to use 1.016, got just the little jump I needed, and the tone change is only perceptible to me. Actually made my voice sound a little more "mainstream" as I only have one octave and its in the lower range.

Valley, thanks for the tip on recycle. I'll check that out also.

This forum and "T" have made the recording life of this rookie multitracker alot easier. Thanks!

Also you could try exporting to .wav and using Audacity's time stretch function - or get Acid Express for free and do it there. Acid Express doesn't let you save .wav files, but you can route the output to any other recording software as an input and re-record the increased speed version in that software while playing the file back in ACID Express.

Thanks Scott. I've seen that a lot of people here use audacity but up til now I couldn't figure out why I would need it. Once I use it though, I prob learn a whole bunch of reasons why I need it but just didn't know. :)

Thanks,

Excuse the dumb question, but how exactly is this done?

Assuming you mean recording one app with another in real-time; it depends on your soundcard. You probably have an option to record the wave output in some way, rather than a hardware input.

eg: the outputs of my Delta 66 monitor mixer appear as an extra pair of ASIO inputs, allowing me to record any mix of inputs and outputs I set up..

IIRC SBLive cards also allow you to select the main wave output as the recording source, or a "what you hear" option which is essentially the same as my extra input pair from my Delta card.

I'm sure there is a way to do it if you poke around a bit.. :wink:
