What's your favorite audio codec?

Jc51373, I am also a Mac user, so I understand why you would use ALAC. If I went lossless, I would probably go for it too because it's a bitch to deal with the other formats on OSX.

The only reason why ALAC is inferior to some other lossless codecs is that it doesn't compress as much and takes longer to encode. So yes, if you don't care about hard drive space, it doesn't matter.

As far as your 1:1 comment goes, while they are sonically identical, space-wise the ratio is more like 1:2. Lossless cuts storage in half (roughly).

I think though, that storage is a factor. For a PC you can always get more space, but what about a portable player? As far as I know, the biggest hard drive on a portable player is 80GB, not that much for some people. I'm interested to know how you get around this problem.

Ledhed2222-Now I understand where you are coming from.

To answer your question-I have two completely different libraries. One is all AAC on one PC, and the other ALAC on my MAC, which is dedicated to audio for the most part. For our iPod (80gb) we just sync off home PC and the library is AAC, and we use about 60GB of space for the portable library.

You can also have iTunes boot to two diffent libraries, where it will prompt you to choose when you click on it to open. This might prove useful for you.

I like this idea a lot but it poses two problems in my mind: you need A LOT of storage on your computer (I just have a mac laptop, I'd have to buy a huge external drive) and you have to spend time putting all of your music into two formats. Do you have a way to speed this up? How do you boot two libraries with iTunes?

When you say huge, how huge? How many gigs of music in total do you have?

To boot to a different library, hold shift then click iTunes while holding shift, you will be prompted to either choose or create a new library. iTunes (2) is the default I believe.

And yes, you would have to spend time putting music into two formats and then manage two libraries as well. I personally find it to be totally worth the (small) effort for my needs of both portable and hi-end home audio. I personally wouldn't dare put an MP3 (AAC) near my home system, and feel it is wasteful to put lossless on my wifes' IPod (she is the primary user of the portable audio). So this method allows me more control over my entire collection. All you have to is burn everything in Lossless and then have iTunes downgrade the other library to AAC. You can always take away data, just can't ad-which I am sure you are aware of.

But in the end, you have to have the space for it.

If I hadn't already ripped 15 GB of music into lossy, I'd take your advice Jc51373! I like your solution.
