Scream can save files in SAC format. See Recording Options.
Files are recorded using the parameters specified in the recording options, including fragmentation and directory. Filenames are created using the same date-coding system as ‘.gcf’ files, but use the extension ‘.sac’.
Since SAC files do not have any support for discontinuous data, if a discontinuity is detected in the data stream, then the file will be closed, and a new file opened with a filename timestamp matching the start of the new file. Note that this operation overrides the fragmentation (size or duration) specified in the setup.
Normal Filestamping will resume on the next fragmentation time/size interval. E.g. If 1 hour files are specified, then a new file will be opened on the hour, every hour, whether or not a discontinuity during the previous hour caused a new file to be opened.
The byte order used is specified in Recording Options.
Stream identifiers are placed in the SAC header in the following positions:
Stream ID= KCMPNM
System ID= KSTNM
