How to lower BPM of a Track?
View this Thread in Original format

How can I set the BPM of a track slower or faster?

Let's say I have a track at 140 BPM, and I want to make it originally be at 130 BPM.

I know I could use my CDJ's or a DJ Software like traktor and record the track

but if I play it at this speed it will sound weird.

it's there a way to record it at this speed without sounding weird?

Thanks.

on your cdjs you could use the button that keeps the pitch the same so really it won't sound that different.

Or

Use some kind of time stretching software.

That really screws up the sound quality - especially over a difference of 10 bpm.

Audacity has a feature that lets you change bpms by entering the original speed and the new desired value, but I haven't used it much other than on short samples so I don't really know what kind of effect it has.

Large Time stretches are the realm of some seriously expensive software. Even then it's not perfect.

Is it a whole track, or just a loop?

You could try ableton Live (Just about best bang/$ ratio for this), or get into Recycle and REXify it if it's just a loop.

If you're serious you can spend the big $$ and get

but it's $799..

sony sound forge is good for changing bpm's. i use it when im remixing a track.

Ableton live does pretty well with BPM changes. Obviously once you get to the big changes, it starts to fall apart, but I can't think of a program that doesn't fall apart at some point.

Well, you only have two choices: Lower BPM in proportion with the pitch (the song well be detuned down a couple of centitones) or compromise sound quality and stretch it. You can't expect 100% quality and stretch the track alot, it's just not possible.

I've heard some Chill out remixes, they are at about 110 BPM, and the track is originally at 140 BPM.

how is that possible then?

by the way, thanks for everyone who replied =)

In my experience Sony Acid works best for doing this. Lowering the rate of a track effectively lowers the sample rate. This is bad since the software has to interpolate the spaces. So if you want to seriously get the best quality you should lower the pitch too. This can be done in Sound Forge and Cool Edit Pro.

Thanks, drive up to the next window please.
