Hi,
i am interested in converting a music mix to 180bpm. The problem is that the originator file has several songs with varying BPMs Does anyone know if audacity would still import the file and convert it (with the varying BPMs) to a single 180BPM? if not, do i have to do it manually in audacity of some other program? Thanks for any help.
If you haven’t done so already you’ll need to count the current BPMs so you know how much to change by. And, the best way to do it is to tap your foot and actually count the beats for 30 or 60 seconds.
The Change Speed effect will change speed and pitch together (like speeding-up or slowing-down a record or tape). This is the “easiest” algorithm and you don’t get “strange” side effects (except for a pitch shift).
Change Tempo can change the tempo without affecting pitch.
Sliding Stretch can also change tempo without affecting pitch. (And, it’s generally recommended over Change Tempo eve if you are not “sliding”.
the best way to do it is to tap your foot and actually count the beats for 30 or 60 seconds.
So if the real question was how to I tell the original BPM, that’s the way. Once you have that number, there are several effects that can help.
If you’re after what happens when a Vinyl DJ changes his Techniques SL-1200 Turntable, that’s Effect > Change Speed. That’s also the effect least likely to damage the sound.

Please note that if you’re really after the Disco Effect, you’ll need to split up the songs into multiple tracks so you can overlap the outro of one with the intro of the other with the Time Shift Tool (two sideways black arrows). Then Effect > Crossfade Tracks. If you do that just right you can cause chaos on the floor as the dancers figure out what you did.
I’m not a fan of the songs that leave you hanging for 30 seconds in the middle with no beat at all. I’d be cutting around those.
