How to change the tempo of an already recorded project?

Hello, I'm recording a song, and after a while Ive decided it was too slow. How to I increase the speed of all the tracks?

Is it all audio?

If so, rerecord everything again at the correct tempo. You won't like DP's algorithm for this. It's old and it sounds unacceptably bad.

Or finish your song at the current tempo and then use MachFive to speed it up (this sounds pretty good to me).

FM, you're referring to the Ircam Tools in M5, correct?

I haven't tried them yet myself, I recently had to deal with this issue myself when the bandleader said he felt the song sounded slow in places. I challenged him on that, and mention this because the OP might find this advice useful.

When you think something is too slow, always evaluate whether it just FEELS too slow. Sometimes this is because of how instruments are locking in (or not); whether there is a back beat, rigid military-like quantized feel, etc.

How parts are articulated can also have an impact, but more often than not, I find that "too slow" is a psychoacoustic effect that is easily corrected by listening to two instruments at a time until identifying the culprit, then dragging that one forward (or behind) until things sound energetic and "not slow".

Correcto.
I think they are very good (one for "destroying" and one for real processing. The last two in the oscillator menu)

There's also IrcamLab TS but I agree with FM. If the song is worth anything at all, it's worth playing again (and again, and again...).

If duplicating the performance is an issue, well... all the more reason to play it again and again.

It always sounded unacceptably bad to me....

I find DP works moderately ok for tempo change, but with monophonic audio, like individual vocal tracks, only. If your project is MIDI plus vox, give it a try within DP. If you recorded a live band, feggetaboutit.

Ircam TS plug is not perfect, but has proved to be quite good in my last experiences.
Takes a little tweaking time to get where you want, though.

If it's just a few beats a minute, I've had success with Amazing Slow Downer. Process each track...whether mono or stereo and reimport or open a new project.

Also works on reasonable pitch change.
