STREAMING MENU
♦
The
Title
field allows you to enter the stream title displayed to listeners and on public listings, such as
shoutcast.com.
♦
The
Enable
control enables or disables the stream. When enabled, the encoder will continually try to
connect to the specified server.
♦
The
SBR (Spectral Band Replication) Mode
toggles between Off, On, and Oversampled. We recommend
setting this control to Off (AAC) for bit rates of 160kbps or higher, On (AAC+) for bit rates of 96kbps or
lower, and Oversampled for bitrates between 96 and 128kbps.
♦
The
Channel Mode
menu provides a choice between Mono, Stereo, Stereo Independent, Parametric
Stereo, and Dual Channel. We recommend setting this control to Stereo for bit rates over 40kbps and to
Parametric Stereo for bit rates of 40kbps and lower. Mono should be used only if the program material is
mono. Because the Stereo Independent and Dual Channel settings force the encoder to divide bits equally
between the left and right channels instead of allowing it to allocate the bits as needed, we recommend
not using these settings unless you have a specific reason to do so.
♦
The
Bit Rate
menu allows you to choose encoding bit rates between 16kbps and 320 kbps. Your choice of
bit rate settings will significantly influence the audio quality of your stream. However, you will also need
to take other factors into consideration, such as the total amount of bandwidth available for the stream,
the anticipated number of users, your maximum upload speed, and the download speed limits of your
intended users.
♦
The
Audio Bandwidth
menu allows you to set the high frequency range of the stream between 8 and
20kHz. Unless you have a specific reason to set the bandwidth manually, we strongly recommend leaving
this control set to Encoder Default.
♦
The
Sample Rate
menu will either maintain Omnia.7’s system sample rate of 44.1kHz or 48kHz (depend-
ing on the sample rate setting) in the encoder, or result in a high-quality re-sample to 32, 44.1, or 96kHz.
