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."

Yes, what do i know.

Most will not hear it because they dont have the equipment. (monitor quality speakers ect.)
Also the majority of music is beat, emo orientated.
It will comes into its with music with higher timbral complexity.

"The advantages of 24-bit audio will vary with different recordings, different equipment, different listeners--but if you’re an audiophile with excellent gear and a trained ear, you should notice the bump up in quality. Now that we’ve got a handle on 24-bit audio, it’s time to broaden our focus; bit depth and sample rates aren’t the only factors in the quality equation."

It was a simple question. Your defensive tone right at the opening is really the whole answer needed...

"audiophile with excellent gear and a trained ear" have been shown, again and again, to be generally unable to demonstrate their claims when any sort of rigour is applied to them. And no wonder, their brains are the most invested (emotionally or otherwise) in those claims, and are also treated as a self-contained instrument of judging them (vs. following an essentially scientific methodology in ABX)

I think that most people who think that one format is better than another in terms of sound quality would be surprised how difficult it is to tell the difference when they have actually tried to.

Having said that, you are right, there is absolutely nothing wrong with spending funds on higher quality equipment or going for 24bit 96KHz tracks instead of 16bit 44.1Khz tracks if thats your thing.

However, like most things, if you are making a claim, there will always be someone ready to swoop in and ask for some evidence to back it up.
