[rec.music.cd] What is this BitStream thing???

jimu@minnie.cs.su.OZ.AU (James Bryant Uther) (06/04/91)

	HELP!!
  I'm trying to find out (for a friend and for personal interest) more
about the fancy D/A algoritms people like Philips and Sony are using.
Could someone please explain to me, or
point me to some papers, that explain oversampling, BitStream, and
similar systems?
Is BitStream a trade name?, because I haven't found anything on it in
the litrature.
	Thanks and paghty

Can't help you with BitStream, but as for oversampling, see:

Wayne Schott, "Philips Oversampling System for Compact Disc Decoding," Audio,
April 1984, 32-35.

For a good general text, see:

Ken C. Pohlmann, Principles of Digital Audio, (Indianapolis, IN: Howard W. Sams
& Co., 1985). (There's a second edition out now.)

Pohlmann also wrote a good explanation of the MASH ("1-bit") D/A in his
"Insider Audio" column in Mix magazine a year or two ago.
