About Options in the Bitstream Pane
These settings are stored in the finished stream for use by the playback device. Leave
them at their default values unless you have a specific technical reason for changing
them. The following export options are available in the Bitstream pane:
• Center Downmix and Surround Downmix pop-up menus: If your encoded audio has these
channels, but the player does not, the channels are mixed into the stereo output at
the specified level.
• Dolby Surround Mode pop-up menu: When encoding in 2/0 (stereo) mode, specifies
whether the signal uses Dolby Surround (Pro Logic).
• Copyright Exists checkbox: Select this option to specify that a copyright exists for this
audio.
• Content is Original checkbox: Select this option to specify that this audio is from the
original source and not a copy.
• Include Audio Production Information: Select this checkbox and fill in the fields below
to specify how the encoded audio content was mixed. Playback devices may use this
information to adjust output settings.
• Peak Mixing Level field: Specifies peak sound pressure level (SPL) (between 80 dB and
