The best I can dig up is that Apple Lossless Encoder is based on AAC encoding, but that may be people's impressions because the file type is the same. A lossless, proprietary compression is applied to what I guess is a compression-less (exact copy) AAC. I arrive at this because if you don't have QuickTime 6.5.1 or higher, iTunes will still encode/decode ALE -- only it ain't ALE, it's AAC at a high setting.After much testing, it is my conclusion that ALE is just as good as WAV or AIFF, at 50% space savings. However, I will probably live to regret my decision to encode with ALE.
Please post with anything you discover about origins of ALE. I have done listening and file comparison tests, but would love to be able to explain this lossless compression to myself and others in some kind of context.
