[rollei_list] Re: OT: Vinyl and CD's

Hi Austin,
yeah, there was a lot of pretty shoddy playback equipment in the first generation of players. Just like early digital cameras ;-)
As for hypercompression, I'm referring to the fact that on a carrier medium with 96dB of headroom (compared to 65-70 on vinyl, on a good day) pretty much all releases the last 10 years (or more) have between 3-9dB headroom, if you're lucky.
I think that's why many people prefer vinyl (and I do too if the alternative is 'crushed' digital), due to the physical constraints of the medium (keeping the needle in the groove), you automatically get about a 12dB crest factor, often more. Meaning that the dynamics aren't removed as they are on pretty much all CD's made after the advent of the Digital look-ahead limiter (i.e. Waves L1, then L2).

So, not lossy compression (MP3), but compression & limiting waaay past what is sane, listenable and musical. 

Cheers,
Thor

Hi Thor,


Unfortunately, early CD's sounded harsh (poor converters and
brickwall filters)
As well as poor playback equipment. Until the introduction of oversampling filters on CD players, they used third order filters, which have aliasing issues. With an oversampling filter, a first order filter can be used, 
which removes the aliasing issue.


...and later ones largely fell prey to
hypercompression.


Huh?  CDs are not compressed.

Austin
