Just saw this over at CNET. It covers hi-rez with a slant towards being less technical. Not much about SACD other than the Meyer-Moran study.

EDIT: I just jumped into some of the comments. Not bad, mostly, but one reiterated that CD's sucked because they "left everything flat."

So... CD's leave everything flat. The hell's wrong with that? It's not like CD's need tone shaping or compensation curves.. a la RIAA with turntables. Are people claiming that sound quality would be better if we did RIAA style crap on everything? Hey, let's just compensate and then recompensate a thousand times and see what's left of the sound. If it's good once, it's gotta be better thrice.

The recording and engineering are basically everything. If the recording sounds good and is well engineered, it will sound good on CD, SACD, HR PCM, or vinyl, though the latter could very possibly have pressing issues and/or noise problems. You don't want to produce at 16/44, but playback at 16/44 is fine, if not necessarily perfect. 24/88 solves pretty much all of the issues with standard res.

I have a few albums where I'm quite convinced that things sounded great in the studio but when they pushed it to the CD it came in too hot because there's no overhead when burning a CD. So, I'd love to hear the studio master files and tapes and compare those to the CD's I have. The bonehead who worked on Heather Nova's South album has clipping on every track. Every one! There's no way the guy at the mixing console didn't catch that in the studio. Then again, signal headroom exists in the analog world... not the digital.

That just sounds like typical loudness war mastering to me. There's nothing in the CD spec that says you have to master loud or get anywhere close to 0dBFS. Somebody wanted it that way, to be "competitive."

That's a CD release. You'll note that most tracks have well over 5dB of headroom left.

Hmmm... all the peaks I just looked at are -0.1 dB. Yeah... stupid loudness wars carnage.

So... does DSD have a difference in terms of headroom? PCM does from zero downward. How does DSD work?

I thought most labels/distributors actually required that the cd release have a certain level of loudness.

Do you think there may be an acoustic leak from the jack hole? ~Tyll Hertsens

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin
