Convert Text Markers to CD
Text Markers can be converted into a CD.
Simply right-click on a selection of Text Markers in the Markers Tab pane and choose Create CD Disc.
This will create a new CD disc and select it. A final Stop marker will be added at the end of the next Clip found (if
any) after the TimeCode of the last Start marker. (So it only creates CD Start Markers on the first and intermediate
Cues, but also creates a Stop Marker after the Cue that has the last Start Marker, in order for the CD to be valid).

D.4 High Frequency DSD Signal + Noise Level
The accumulated RMS signal + noise level of the DSD signal, measured after a 40 kHz Butterworth 30dB/Oct high
pass filter and a 100 kHz Butterworth 30dB/Oct low pass filter, is maximally equal to the RMS level of an input sin-
ewave with a peak amplitude of -20 dB SA-CD (see D.2).
The averaging filter used to calculate the RMS level must be a first order unity gain IIR filter with a coefficient of 1/
524288 ( 2-19 ), corresponding to an IIR filter with a cutoff frequency of about 0.85 Hz.

E.2 Analog Post-filter
To protect analog amplifiers and loudspeakers, it is recommended that a Super Audio CD player contain at its out-
put an analog low pass filter with a cut-off frequency of maximum 50 kHz and a slope of minimum 30 dB/Oct. For
use with wide-band audio equipment, filters with a cut-off frequency of over 50 kHz can be used.
Note: When releasing material at higher than 44.1 or 48 kHz sampling rate, Merging recom-
mends to add a gentle low pass filter (typically 6 to 12 dB/octave) in the range from 30 to 50 kHz
for all recordings made originally in DSD 64. The corner frequency of such low pass filters can be
doubled whenever converting from DSD 128 and even quadrupled when converting from
sources originally recorded in DSD 256 (which essentially means that even when converting
from DSD 256 to PCM at 192 kHz, there is no need to add such a filter).
