I'm Thinking Of Converting...., Conversion between 44.1 and 48kHz Options

[Kevin Krohn]

Hi all.

I was so excited to learn of the upgraded converters in the latest iteration of Garage Band that I decided to use it to set my guitarist up for recording all his tracks.

Too bad I didn't do my homework; the top quality setting in GB is 24-bit 44.1kHz, and the rest of my project is being recorded at 24-bit 48kHz in Pro Tools.

Now, when I dragged the higher-rate project files into the GB projects GB converted them flawlessly.

What I need to know is, how do I get them to go the other way? I need to convert from 44.1 to 48kHz. Some posts online suggest this might actually make it sound a tad better; I'll settle for not sounding any worse!

I don't want to use something like Audacity in case the quality of the conversion is questionable.....

Does anyone out there have any experience up-sampling or using GB files in Pro Tools sessions? There are a million programs out there that manipulate audio files, but for all I know Quicktime or iTunes can do it.......hoping someone knows something I don't!

Thanks.


Okay, may have partially answered my own question.....

Quicktime Pro does indeed allow for saving a 44.1 file in 48kHz, and there is a slight increase in file size, indicating something is going on...no strange artifacts or differences in tempo or pitch......

However, the original question still stands.

Is there a way to just drag the files into Pro Tools and have the conversion happen the way it did in GB? I can't test the theory, the Pro Tools rig is in another state, I use GB and Logic exclusively.

Nice to know I can do it in QT, even if it will be a total pain to have to convert that many tracks. Why didn't Apple just go all the way with those converters?!

Yes.

Create a new session in ProTools with the settings you require (file type / sample rate / bit depth). Go to File > Import Audio and select all your files, choosing "Convert All". ProTools will then upsample everything to match the new session's settings.

The real question is, if the session is intended for CD released why are you recording at 48K?
