itunes at 44kz wav?

I'm ripping a ton of borrowed CDs and I want to make sure I do it right the first time. I reckon itunes is a good choice since it does the tracknames etc. better than the other rippers I've tried.

I presume there is no difference between different rippers quality when it comes to 44khz 16bit wav since it is a lossless format, but is there any point ripping at 48khz? I think it has to upsample since 44 is the quality of the CD but maybe it is useful later on down the line, as you have to do it anyway in some DAWs (?)

rip to 44.1 k, if you want to upsample it (to use in your daw) then you can do it then instead of taking up more room in your computer. that's what i'd do anyway

Key question - why do you need to upsample?

why do you need to upsample?

What sample rate do the various DAWs use? I just thought they might have to upsample it (and perhaps do it badly) when importing it into FL or Reason etc.

I assumed it would be if he was running a project at 48 k and he didn't want any sampling mismatch shiz

You should set (or at least know!

) your project sample rate - if not then I imagine it would be at 44.1kHz by default, and so upsampling is pointless to all intents and purposes. Any upsampling for additional precision during processing is handled 'behind the scenes' by the plugin doing it (some do, some don't).

It's true that you get different quality of SRC though, and most DAWs have SHOITE SRC.

See here: http://src.infinitewave.ca/

Today's top tip for top of the tree (

) SRC is SOX. It's a command line thing, but once you have set it right (say, always output at 44.1kHz, ultra high quality) you can have a shortcut to the batch file on your desktop, drag all your files on it and smile as it does its thing. Bloody brilliant.

That better than r8brain ?

Seems not from those graphs...

Are you looking at r8brain free? Compare the passband/transition band graphs, SOX wipes the floor with it in VHQ...
