FLAC, WAV or AIFF question

Most of my ripped CDs are in AIFF, except for the special ones that get a WAV copy.

FLAC, as noted, is not supported by iTunes. I use Pure Music, which does support FLAC via iTunes by creating a pointer to the files. I believe the only caveat is that once you import the FLAC files, you can't move them without breaking the link. Not a big deal; I just keep all FLACs in a special folder.

You could go with WAV, but there goes your metadata.

I would personally go with FLAC, it is the most prevalent of the audio codecs and has very good support from all mfgrs. except Apple - big surprise there, huh?

Nonetheless, using a program like dbPowerAmp allows one to transcode from/to virtually any codec to another. And it can do so as a batch, so you can set it to begin transcoding an entire library when you go to bed and it will be done when you get up in the morning...

The advice above (although accurate and well-intentioned) doesn't take your whole situation into account.

Audirvana+ in iTunes integrated mode will allow for you to play either FLAC or WAV files from within the iTunes interface. I suggest FLAC over WAV as far as download format to reduce hassle re: metadata. However, to make these files playable you need to add them to your Audirvana+ library. This creates a small pointer file that shows in iTunes and tricks iTunes into finding the FLAC or WAV files and playing them.

If you are running A+ version 1.x, this was the common way to go. However, version 2.x is a different world, because A+ now includes full database functionality when run WITHOUT iTunes integrated mode, and the sonic benefits are substantial. Granted, your might have some hiccups making the change to running without integrated mode, but IMHO it's worth it for:
- better sound quality
- no need to convert file formats
- no need add iTunes track to A+ library as described above

Downsides: Need separate new remote app for iphone/ipad control (works great, but I am still more comfortable with Apple Remote app)
Messy to restore some missing artwork after making the changes

If you just want to stick w/what you've got now, you can convert the FLACs to AIFF before you add them to your iTunes library using MAX or something similar, but that won't take advantage of the sonic improvements recently made with A+ 2.2 etc. Cheers,

I started with my entire CD library ripped to wav; sounded better than FLAC for local hard drive play. However once you try to stream music WAV sucks big time for meta data tagging and no sound difference versus streaming lossless FLAC; all mys music is now FLAC. Since AIFF is an Apple only, evil empire format I'll never use it...

For myself, I download WAV because I think it sounds better than FLAC. Once I have the files on my hard drive, I transcode to FLAC and MP-3. From there, I put the WAV files on a backup HD, so if there's ever a problem, I can go back to them and start over. This way, you don't have to make any sacrifices.
