How do I convert 24fps-shot feature's audio to 25fps?

I produced a feature at 24fps. Which is great for the cinema and the States, but not so great for UK DVD...

I need to convert the 24fps audio tracks to 25fps so that a master can be delivered to the DVD manufacturer.

Don't have the budget to take this to an audio post house at this stage, so has anyone done this on ProTools themselves and if so what did you do to compensate for the speeding up of the audio by 4.1% to avoid it sounding like Alvin and the Chipmunks?

I have a 25fps master of the picture already btw.

Any advice would be very gratefully received...

Thanks!

Ben

In Adobe software, simply check "maintain audio pitch" when altering frame rates or audio file stretching / shortening. I've never used Pro Tools, but I would assume it has an equivalent feature. If not, you could always download a month's free trial of Adobe's stuff.

Just saw this. Pro Tools has a built in pull-up feature in session setup (ctrl+2 on the keypad on windows, cmd+2 on mac). At the bottom is Timecode Settings, where you can set the new audio rate. So if your video is now 25fps but the audio is from 24fps, just select 25fps from the audio pull up/down and you're done.
