4 Recording and playback

Scream! allows you to record all incoming data and store it on the

local hard disk. To do this, you should select the streams you want to
record from Scream!'s main window, right-click, and choose Start
recording
from the pop-up menu. The streams will display Yes in the
Rec. column to indicate that they are recording.

When Scream! starts recording, it starts at the earliest point in the

current stream buffer, and immediately records all it can. For
continuous streams, the recorder will soon catch up with the real-time

data.

By default, recorded data is placed in a data directory within the
Scream 4 installation, in GCF format. Scream! records files for each

stream separately, which it puts in that stream's own directory. This
directory may contain one or several GCF files.

Scream! has a number of options which allow you to change the way
data is recorded and filed. From the main window, select Setup... from
the File menu to open the Setup window. Click on the Recording tab.

(Scream!'s setup window also provides a number of other kinds of
options. Consult Scream!'s documentation or online help for more

details.)
