Copy Protection
These settings determine
how the clip is handled by the RealPlayer
client.
■ To allow RealPlayer Plus users to save
your clip using the RealPlayer Plus record-
ing feature, select Allow Recording.
■ To allow RealPlayer users to download
your clip to their hard drive, select Allow
Download.
If you don’t want to allow RealPlayer users
to make copies your clip, deselect both of
these options.
Audio Format From the pop-up menu, se-
lect the setting that best matches the type
of audio you are bouncing. A brief explana-
tion of each format is displayed.
Target Audience Select the connection
speed that most users downloading your
clip are likely to have. This setting deter-
mines the bit rate at which the audio will
be encoded. Depending on the file type
you choose (see below), you can choose
more than one connection speed.
File Type This option determines the com-
patibility of the output file with different
RealAudio servers and clients.
If you select SureStream, you can select
more than one connection speed under
Target Audience. With this file type, multi-
ple bit rate streams are encoded into a sin-
gle output file. Files encoded with the Sur-
eStream option are larger than Single Rate
files, and can only be played back from G2
servers.
Select the “Include RealPlayer 5.0 Compat-
ible Stream” option to include a backward
compatible stream that can be played on
older version 5.0 RealPlayers. (This back-
ward compatibility is only available for
SureStream-encoded files.)
If you select Single Rate, you can only se-
lect one connection speed under Target Au-
dience. With this file type, a single stream
is encoded into the output file. Files en-
coded with the Single Rate option can be
played back from either a standard web
server or a G2 server.
Auditioning RealAudio clips
If you are using Digidesign Sound Drivers
and want to use a RealAudio player while
running Pro Tools, make sure that Opera-
tions > Active in Background is not selected
so the player can use the Digidesign hard-
ware.
MP3
The MPEG Layer 3 compression format
(MP3) is used for streaming and download-
ing audio over the Internet, and for play-
back on portable devices.
The MP3 encoder file is stored in a folder
named Codecs inside the DAE folder. This
version of the encoder uses the latest tech-
nology from the developer of the MP3 for-
mat, the Fraunhofer Institute. It features
improved processing speed and quality,
and supports both constant and variable
bit rate encoding.
The MP3 encoder installed with Pro Tools
is a fully functional 30-day demo version.
To purchase the full version of the MP3 en-
coder, visit Digidesign’s website.
