Apple Apple has open sourced ALAC. "The Apple Lossless Audio Codec is an audio codec developed by Apple and supported on iPhone, iPad, most iPods, Mac and iTunes. ALAC is a data compression method which reduces the size of audio files with no loss of information. A decoded ALAC stream is bit-for-bit identical to the original uncompressed audio file. The Apple Lossless Audio Codec project contains the sources for the ALAC encoder and decoder. Also included is an example command line utility, called alacconvert, to read and write audio data to/from Core Audio Format and WAVE files. A description of a 'magic cookie' for use with files based on the ISO base media file format (e.g. MP4 and M4A) is included as well. The Apple Lossless Audio Codec sources are available under the Apache license."

Everyone can agree lossless always sounds better than MP3, especially electronica and classical; psychoaural compression has its limits.

I can't; with "always" this claim is also too strong.

You can quite easily find examples / settings where lossless will sound better than lossy, sure, but not anywhere near "always" - not only this requires just one counterexample to falsify, there are also many cases of people (also those previously thinking they can easily hear the difference) who were "shocked" at how low bitrates they still couldn't tell a difference from the originals, when performing for the first time a proper ABX testing.
