Burning of CDs (deLuxe version only)
This chapter introduces you into the basics of burning audio
CDs, and the functionality of the burning functions of
MAGIX audio studio generation 6.
RedBook
To standardize the data structure of CDs and to make them
compatible with the CD drives, Sony and Philips laid down
individual standards for the various types of CDs. The
names simply arose from the color of the books in which
these standards were recorded. Besides of the RedBook for
audio CDs, e.g. there is one YellowBook for CD-ROMs or
one WhiteBook for video CDs with MPEG format.
Among others, a sampling rate of 44.1 kHz and 16 bit
resolution were laid down, and these are supported by CD
players as well as by audio CDs. The audio CDs,
furthermore, must consist of 1-99 tracks that can be directly
jumped to by CD players. Information on number and
length of tracks and pauses are copied from the CD to the
player via special subchannels.
Thanks to MAGIX audio studio generation 6 you may
directly master and burn audio CDs from any multitrack
and any wave project in RedBook standard. Besides the
actual tracks, all required subchannels and data information
is created on the CD blank as well.
Data Transfer
Burning CDs means making special demands on the data
transfer from the hard disk to the CD recorder. The data
must stream continuously to the recorder. If, at any time
during writing, the temporary memory of the recorder
should be left without data, a so called buffer underrun
error will occur that will render the CD unserviceable. This
necessitates the use of a fast SCSI or IDE hard disk. The
mean access time should be 15 ms or better, and the per-
manent data transfer rate should not be less than 800 Kbyte
per second.
Burning CDs in MAGIX audio studio
Some years ago, there was but a small number of select
studios in a position to carry out CD mastering. Today,
writing of audio CDs is nothing exceptional any longer, and
permanently dropping prices for CD-R burners and media
are within everyone’s reach.
On the CD the audio material is stored digitally, and these
data are read by the CD player and transformed back to the
