Can I convert an entire iTunes library to a lower bitrate?

post #1 of 8
Thread Starter 

I know you can do it for the ipod but was wondering if you can do it for your desktop.

 

I recently copied/pasted my entire library from my home computer to a new desktop at work.

Most of my music is at 320+ and I dont need that level of quality at work.

 

Would like to replace all of the 320+ with 256 versions without making duplicates of each song (one at 320+ and the new one at 256).

Have you tried using Foobar? easy to convert.

All2MP3 is a Mac program that works well in my experience and is very easy to use. It will make duplicate files though...

Yes but wont this make duplicate files?

 

Is there no way to do this in Itunes?

 

ITunes allows you with one button press, to downgrade all of the music on your ipod.

Is this not possibly for the hard-drive based library itself?

It will but here's how you deal with it. First, assign a different folder for the duplicate files. Next, go back to the iTunes folder in Explorer or whatever OSX calls theirs, click on the first folder, hold shift, then click on the last folder. Once highlighted, right click on any folder, then click "delete." Empty recycle bin. Now, go to the folder where the duplicate files are, click on the first folder, then hold shift, then click on the last folder. Right click on any folder, click "Cut," then go to the iTunes folder. Right click there and click "Paste." You now have the lower bitrate duplicates in the iTunes folder, and the higher bitrate files are gone.

AFAIK, if you want to do it this way, you load the duplicate lower bitrate files on the iPod then disconnect, then you go into the iTunes folder, click the first album folder, hold shift, then click on the last folder, then right click on any of the highlighted folder, then click "Delete." Empty recycle bin. Now hook up the iPod again and copy the library on it. I don't think iTunes will just lower the bitrate and overwrite existing files - this feature was designed so that your computer with a larger storage will store all the higher resolution files (like ALAC or 320VBR) as a master copy, then if you want to cram as many of them as possible into an iDevice, it will lower the bitrate on the fly while you sync, instead of maintaining two libraries in the same computer, which will confuse iTunes and make you pull your hair out.*

 

Personally this seems like a longer process than the first one.

 

 

*iTunes declares ownership on my FLAC files, despite the fact that it was assigned a specific folder and it can't read them to begin with, leaving MediaMonkey dazed and confused like a hacking victim in a Hollywood movie, and Apple fans consider this some kind of a victory over other music players, even though it looks like Scorched Earth policy to me, since iTunes basically went, "oh this is audio...can't read but it's mine nyahahaharhar! suck it, MM and Foobar! if he can't listen to them through me, he won't listen to them through you!"

Thanks for the reply.

The only reason why I cant do the first option is because I wont have enough space to hold both version of the files. It would be something like 3-400 gigs and my HD is only 250 at work, hence my desire to lower the bitrate in the first place.

The second option makes more sense as I wont have to have duplicate files but...how do you copy the library off of an Ipod?

 

Dont you need some 3rd party software to do that?

iTunes doesn't do that anymore? I once hooked up my iPod on a new computer and I just saw it copied my library too. This was way back in 2008 or so. I just assumed iTunes always does that.

Wait so where are the files now? I assume they're at your computer at home, how much spare memory have you got in there? You can do that there then copy the lower bitrate files to a portable HDD to bring to work. I mean, I assume you at least have an HDD to take them to your work computer, so you can either do the conversion on your personal computer, then take them on an HDD and copy the lower bitrate files into your work computer. Not enough space on your home computer too? Hook up the HDD and have Foobar output the converted files in there. It'll be a bit slower but it's doable. Or do it by batch - a few albums converted at a time, then highlight, right click, click on "Cut," then go into the portable HDD and click "Paste." Depending on your RAM and processor, you can keep converting while this transfer is happening. I've done that back when 160gb portable drives were still well over $100.

 

This isn't really the kind of convenience you can get with a brand new iPod syncing, but a lot more like when I had to figure out how to remove and replace contents in an iPod, which isn't as straightforward as my Apple friends always think when there's drag and drop (who always reply with a, "why would you want to do that?").

There is a pretty easy way.

 

What you'll do is go into

 

iTunes -> Preferences -> General -> Import Settings

 

Import Using -> MP3 Encoder or AAC Encoder

 

Select Settings -> Custom

 

Stereo Bitrate -> eg. 256kb/s (VBR uses the 256kb/s as a minimum threshold)

 

Select OK to accept changes in the dialog boxes.

 

Select files you want to convert in your library -> Right click on one of the selected files -> Create *MP3/AAC version*

 

This will create a second file with the Import Settings you selected in Preferences.

 

Without deselecting the original files delete the selected files.

 

Edit -> Delete

 

This should open a dialog box.

 

Ok -> Move Files to Trash

 

Empty trash when satisfied with the conversion.
