Basics
In order to unify the data structure of the CDs and to facilitate the use of the CD-drives, different
standards were created for the different types of CDs. The names for these standards refer to the colour
of the books in which these standards were written down. Apart from the Red Book standard for audio
CDs, there exists for example a Yellow Book standard for CD-ROMs and a White Book standard for
video CDs in MPEG format. The term "Red Book" stands for "Compact Disc Digital Audio Standard".
The Red Book standard includes the Sampling rate of 44,1 kHz and the 16-Bit-resolution, which is
supported by the commercial CD-Players and is also valid for the audio CDs. Furthermore the audio
CDs have to count 1-99 tracks, which can be directly selected by the CD-players. The information
concerning number and duration of the tracks as well as the breaks are transmitted from the CD to the
CD-player through special sub-channels.
Data transfer
Writing a CD is especially demanding when transferring data from the hard disk
to the CD-writer. The data has to reach the CD-writer in a constant flow. If at any time during writing
the cache of the recorder runs out of data, the "Buffer Underrun"- error message will appear. This will
make the CD useless. For this reason, it is recommendable to use modern SCSI- or IDE-hard drives.
The average access time should be 15ms or faster and the steady Data-transfer rate should not be less
than 800 Kbytes per second. This is the case for all modern hard disk drives.
"Burn Proof" Support
The new CD burner routines in MAGIX Audio
Cleaning Lab 11 support almost all current CD burners on the market. A detailed list of supported
equipment can be found in the "CDR_Readme.txt" as well as the MAGIX website.
When your CD burner is "burn proof" supported, it means that even with high CPU
workloads, no "buffer underruns" will occur while burning is in progress. "Burn proof" support gives you
faster, more secure CD burning. In cases whereby the processor is overstrained, older systems would
break up the burning process, and because the file cache was empty ("Buffer underrun") the CD became
unusable. However, the "burn proof" process continues in a piece-by-piece manner so that it can
continue without error as each new piece of data is read. "Burn proof" support gives you faster, more
secure CD burning!
The Burning Function
The audio
material on the audio CD is digital data, which the CD-player reads and transforms into analogue signals.
The track markers indicate the CD-player, at which point the song starts. The MAGIX Music Editor 3
can write an audio CD right away from the program. The track-markers are set in the track window
before writing the CD. MAGIX Music Editor 3 transforms the stereo sum and the indices into a data
flow, which is directed to the CD-writer.
The CD-R-drive modifies a specially designed layer on the medium using a laser, so that the audio
CD-player will be able to read this information later as digital audio data.
Audio CD creation
1.
For writing an audio CD, the track window must contain audio material. Edit the audio material
using the real time functions of the MAGIX Music Editor 3 deLuxe. The CD will sound exactly
like the playback when you listen to it through your stereo sound card. All Cleaning and
Mastering effects will also be present on the CD.
2.
Mark the starting position of each song by setting (or moving) the track markers. All track
