1. LOWER COMPRESSION BUT HIGHER CPU USAGE
2. NO COMPRESSION MODE TO SELECT

EDIT : But compared with Monkey's Audio, WMA still use more power.

WMA = 34.0MB = ~13% CPU Usage
Monkey's Audio - High = 33.7MB = ~7% CPU Usage

I recently converted from FLAC to Wavpack in order to save a little bit more disk space. I'm not worried about any lost data that FLAC may or may not have thrown away, but I did decode a FLAC file to Wav, encoded the same FLAC file to Wavpack, and then decoded the Wavpack file to Wav and compared the two (Wav files). Also, I ripped the track straight from CD and compared and all were bit identical in foobar2000 and had the same md5 hashes. I only tested one song, but I don't think you will find many Wav files with extra non-audio data from a music album.

Edit: forgot to mention something important. crying.gif

Hence the term lossless compression. It's a good attitude not to take just anything for granted, but did you expect anything else?

Any codec not decoding to WAVs that are bit-identical to the original ones, be it because of a bug or not, does not deserve the predicate lossless, if you ask me. I'm referring to reports about ALAC acknowledging this: 1, 2 and 3.
