Writing
Some years ago, there was only a small number of select studios which were able to do CD mastering.
Today, writing audio CDs is nothing exceptional and continuously dropping prices for CD-R burners and
media make them available to nearly everyone.
The audio material is stored digitally on the CD, this data is read by the CD player, and then it is
transformed back to the analog plane. While in action, track indexes indicate to the CD player which
songs start at which position.
Samplitude Music Studio 15 can also write an audio CD from the program directly. Before the write
process starts, the track indexes are directly set in the VIP
window, and then Samplitude Music Studio 15 converts stereo sum and indexes into a data stream
which is fed to the CD burner.
The CD-R drive modifies an assigned layer of the medium by means of a laser so that an audio CD
player can read this information as digital audio data later on.
Burning CDs in Samplitude Music Studio 15
1. In order to write an audio CD, the VIP
window must first contain audio material. You may either record it new or import existing wave files into
the virtual project.
2. Mix your recordings by means of the VIP window's real-time functions and the mixer window. The
CD will later sound exactly like the playback via a stereo sound card. All settings for the playback will be
audible on the CD, too.
3. Set the track indexes to mark the starting position of each song. If the VIP window contains only one
stereo track (each song is created as separate object), then you may create indexes in Samplitude Music
Studio 15 with the "automatic indexes" button. This will cause an index to be positioned at the beginning
of each object. Tracks and indexes may be arranged in Samplitude Music Studio 15 as you wish. Pause
intervals may be continuously adjusted, and indexes may be set without any pause. Samplitude Music
Studio 15 is one of the few audio programs which features this.
4. When you have made all settings you can write the CD in real time, or you can use the offline function
if your PC is not powerful enough. Now click "create CD" in the toolbar or select "CD -> Create CD" in
the menu. This dialog offers two options:
Write using "on the fly" mode: all effects are calculated in real time.
Create complete, new files. Samplitude Music Studio 15 creates a new stereo file that contains all
information on the multiple-track project.
5. One click on "OK" to start the writing process, and Samplitude Music Studio 15 starts searching for
available CD-R drives. If several drives are connected to the system, then you will be prompted to select
the correct drive. Before burning, the process can be simulated. You can check using the simulation
whether the computer's capacity is sufficient for the writing process.
Once started, the burn process cannot be stopped.

System capacity is essential to the real time CD writing process. Once the writing process started, it
cannot be stopped. The CD will be unusable if the the process is interrupted. When "on the fly" is
selected, the computer must calculate the playback with all real-time functions and simultaneously write
the data onto the CD.
The DSP display is a useful tool to assess possible problems when writing to the CD. The table below
gives you a clue to the maximum possible writing speed. Individual deviations may result due to the
configuration of your system and the speed of its components.
