Speeding up audio recording of piano
on Feb 6, 2012 at 8:36:57 pm

I have an .aif file of some solo piano music for use in an FCP sequence. Rather than edit the music to fit, I would prefer to speed it up by 10% or so.

When I try this in Final Cut (using the Apple AU plugin) in Soundtrack Pro or Protools 9, I can only get to about +5% before I start hearing nastiness. I reckon that this is because, in the speeding up process, it sounds as if it starts to chop out the attack portions of some of the piano notes.

I don't mind if the audio goes up in pitch by 10%, as per old analog tape, but this won't do.

Does anyone know of a way of speeding up this type of audio satisfactorily?

With many thanks,

Harry.

Hello Harry and welcome to the Cow Audio Forum.

10% is pretty severe for speeding up and VERY severe for slowing down.

I suggest you pursue your first idea and edit it;at least far enough down so that you'd only have to smoosh it 4%-5%.

I do that with tracks all the time. I'd do it in STP or Pro Tools.

I've had a lot of luck with Serato Pitch ā€˜nā€™ Time. Surprisingly seems to work better on "dense" music like a full band or orchestral material rather than solo instruments like a violin or piano. Sometimes I will have to do it 2% or 3% at a time rather than all at once. Even PTs time compress/expand tool does a decent job as long as you don't do it all in one shot.

Peace,

Bob
