7. 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.
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 Audio Cleaning Lab SE
can write an audio CD right away from the program. The track-markers are set
in the track window before writing the CD. MAGIX Audio Cleaning Lab SE
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 Audio
Cleaning Lab SE 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 markers can be moved using the mouse or the Track
Wizard (1Click button)
3. Click on the "Make CD" button. In the "Make CD" dialogue you can choose,
if you want to write the CD directly or if you prefer to create an Image file on
the hard disk. The creation of an Image file is then recommendable, when
the available system resources are not enough for writing the CD in real
time ("On the Fly").
4. Now the CD can be written. You will only need a CD-R-drive, which is
supported by MAGIX Audio Cleaning Lab SE connected to your computer
and an empty CD in the drive. Clicking on "Write CD" starts the writing
process. If you should have more than one CD-R-drive connected to your
system, you will be prompted to select one of them.
