SurCode for Dolby E Encoder

page 10

4.1 WAV file format

SurCode for Dolby E Encoder writes the encoded output files as SMPTE 337M .wav files. The

files are normally 24-bit files. You can opt for the output files to be 32-bit.

4.2 Prepend guard band

The SMPTE 337M spec allows for a “guard band” which is a set of empty data points at the

beginning of the file to delay the start of the first frame. Some systems require a guard band for

proper operation.

4.3 Write two mono files

If this is selected, the output will be two mono files. If it is not selected, the output will be one

two-channel interleaved file.

The mono file feature is primarily meant for Pro Tools users, since the Pro Tools region list uses

mono files.

4.4 Use selection start as starting timecode value

If this is selected, SurCode will automatically read the starting time from the waveform selection

of the workstation app, and insert it into the Starting Time of the encoder.

Note: In Nuendo, the selection start time is not copied to the Starting Time until the encoding pro-

cess is started.

4.5 Metadata serial port

SurCode can read metadata through a serial port. This allows it to receive metadata from external

sources such as the Dolby DP570.

The external metadata feature is active whenever a serial port is selected and encoding is not it

progress. It cannot accept external metadata once encoding has started. It is inactive whenever the

selection is “None”.

External metadata will alter the metadata settings in SurCode as they come in. If external meta-

data stops, SurCode will retain the last valid metadata that it received.
