Apple Soundtrack Pro 3 - Manual (Page 437)

• Quality pop-up menu: Choose one of the following for the audio quality of your output
media file:
• Low: This allows for fast transcoding, but at the expense of output file quality.
• Medium: The audio quality is better than Low, but this takes longer to transcode.
• High: This is the best audio quality setting available. Use this setting when the audio
quality is important for the output media file and you don’t mind how long it takes
to transcode.
• Bit Rate slider and field: Move the slider to set the overall audio bit rate for an exported
media file between the range of 16 Kbps (2 KB/sec.) to 256 Kbps (32 KB/sec.), or enter
a specific number in the accompanying field.
About Options in the Streaming Pane for AAC/Podcast Export
The following export options are available in the Streaming pane:
• Streaming hints enabled checkbox: Make sure that this box is selected if you want the
MPEG-4 Part 2 output format streaming settings to be applied.
• QuickTime Streaming Server Compatibility (pre v4.1) checkbox: Select this checkbox if
you want your exported file to work with an older QuickTime Streaming Server (version
4.1 or earlier). You don’t need to select this box if you are using a newer version of
QuickTime, because any streaming compatibility issues are automatically resolved.
• Maximum Packet Size field: Enter a number to specify the largest file size allowable (in
bytes) for a streaming packet in your output media file. The packet size you choose
should be no larger than the largest packet used on any network between the streaming
server and the viewer.
• Maximum Packet Duration field: Enter a number to specify the longest duration allowable
(in milliseconds) for a streaming packet in your output media file. The duration affects
MPEG-4 Part 2 audio only. It limits the maximum amount of audio (in milliseconds) in
any packet, which limits the audio dropout created by the loss of a packet.
