How do I know if iTunes files are all 'lossless'?


Hey gang, bear with me as I know just enough about computers to 'be dangerous' -- my Q., I have hundreds of songs on computer in iTunes and also in my iPod Classic. I'm aware that songs bought through iTunes are MP3 only, but most of the CD's I downloaded over the years SHOULD be as 'lossless'.

How do I find out which files/songs/albums are 'lossless' vs. compressed MP3?

Thanks to any and all.

Denf,

The key is the import settings in itunes need to be set to AIFF, or WAV to get the best sound using itunes. As noted, this will make good sounding files when you import by ripping CDs. After you buy a crappy file from itunes store, it is AND ALWAYS WILL BE a crappy file. Itunes will let you convert it to AIFF later, but the data you want isn't there. It's sorta like magnifying a crappy photocopy, it's too late.
HDtracks and most other good format downloadable stuff is FLAC, so itunes can't read it. If you only use ipods or stuff that can work with itunes (e.g. Squeezebox for home rig) you can just convert FLAC into AIFF with separate piece of software(search FLAC to itunes). For me, the problem is that I also have a Cowon J3 portable that only plays FLAC, so I am stuck for now with two libraries, one in AIFF and one in FLAC. A PITA for sure! Cheers,

That "Create Apple Lossless Version" setting won't add any info to a track. I use it to convert WAV files to Apple Lossless.

The other responses to the other stuff are correct, to the best of my knowledge.

Have your default CD importing setting to either Apple Lossless or AIFF. Apple Lossless is basically Apple's version of FLAC, and AIFF is their version of WAV. iTunes will play WAV. Not sure if iPods/iPohones/iPads will or not. Never tried it.

I rip all my CDs as Apple Lossless. Never heard a difference between that, WAV, or AIFF. Others here have. Others haven't. Everyone's ears, room, and gear is different. Rip a few tracks in a few different formats and see if you hear a difference. Apple Lossless takes up less hard drive space if you don't hear a difference.
I put ALL my cd's to Itunes as ALAC.
Than I make a 2 playlists...one of the lossless files for wireless streaming to the stereo / DAC and a copy into an MP3-160 playlist for car / pod.
Does anyone here use any 3rd party plugins to itunes that allow native FLAC in itunes? Cheers,

Spencer
