Re: Which edition?

D F Tweedie

It is dangerous to interject and answer for another ... but I understand his comment to be that since WAV files are equivalent of CD Audio and those files cut off higher audio frequencies, i.e., those above 22,050 kHz, they are therefore compromised.

If I understand his comment correctly, I would not see it the same way due to my understanding that such material is outside the boundary of human perception.

Alternatively, I do not believe he means that the Audiophile WAV files content has been deliberately low passed, i.e., had the high frequencies rolled off, when they were recorded/ processed beyond and eq applied for musicality.

Are you saying the BIAB Audiophile version has uncompressed files but the files are manipulated to eliminate high frequencies? 
Are you saying that all high frequencies above 12 K or so are eliminated.
That doesn’t seem logical to BIAB development in this current age since the audiophile data comes on a dedicated hard drive and hard drive storage is so cheap, so why would they need to lower the production value  by having high quality wav file samples altered with no very high frequency data.  Are you saying that BIAB is manipulating original high quality studio recording wav files to save hard drive space in audiophile version?

Actually I did mean "compromised" -- the cd-audio format intentionally
cuts out very high frequency data. It's a compromise in order to get
more data into a fixed space. And a .wav file is simply a computer
version of the cd-audio spec. The audio is compromised. Not so that
most people would notice, which is what the engineers and the companies
that were in on the development were counting on. Convenience over

And that is exactly what you should do because it's the maximum amount
of audio data available in digital format. But 16-bit, 44.1K sampling
(which is the cd-audio standard) has admittedly been proven to be much
less complete than 24-bit or 96-bit sampling at 48K or higher. The
higher the sample rate, the higher the frequencies which can be
captured, thus the more complete sound. Which is why CD-audio files
sound better than mp3 files even at their highest bitrate, as D F
pointed out. But just as most people can't hear the degradation between
a full-spectrum vinyl LP recording and a CD-audio recording, so, too,
most people can't hear the difference between CD-audio and MP3 files at
