Consumer-level DAT recorders (and a handful of professional-level units) are usually
equipped with SCMS. Given the number of recording devices that do not include this
type of copy protection, setting the Copy Prohibit Bit does not guarantee that the track
cannot be copied multiple times. WaveBurner provides the option to set the Copy Prohibit
Bit in order to comply with the Red Book standard.

To set the Copy Prohibit Bit
Do one of the following:

µ

In the CD Tracks list, choose Free, Protected Original, or Protected Copy from the SCMS
pop-up menu.

µ

Click the track in the CD Tracks list, and choose Free, Protected Original, or Protected
Copy from the SCMS pop-up menu in the General tab of the Inspector.

Setting Track Pre-Emphasis

The use of pre-emphasis dates from the early days of digital sound reproduction, when
14-bit A/D converters (without oversampling) were frequently used. The high frequencies
of digital recordings were boosted or “emphasized” during conversion (similar to the
RIAA EQ process for vinyl records), then were attenuated (de-emphasis) after D/A
conversion. This tended to mask the inaccuracies of the conversion process.

With today’s advanced digital recording technology, it is recommended that you leave
pre-emphasis turned off, because modern converters are capable of delivering linear
conversions that produce far fewer errors than de-emphasis filters.

Note: WaveBurner only supports pre-emphasis so that old digital recordings (that were
processed with a pre-emphasis algorithm) can be marked as such. WaveBurner’s
pre-emphasis is only a flag intended for the CD player, and does not change the way that
the audio is processed when you burn a CD.

To turn on pre-emphasis
Do one of the following:

µ

Click the PE checkbox for the relevant track in the CD Tracks list.

µ

Select a track in the CD Tracks list and click the Pre-Emphasis checkbox in the General
tab of the Inspector.

Bouncing Tracks

You can bounce a track. As with bouncing a region, bouncing a track saves a processed
version of the track, including all plug-ins, levels, and so on.

To bounce a track

1

In the Tracks list, select a track.

2

Choose File > Bounce CD Track.
