On the Instreamer ICE is only one option available: Line IN.
Input Level
Over the Input level the volume level of the audio source can be adjusted. It can be used to
change the amount of amplification applied to the audio input to increase or decrease
volume. Select “Nominal (0 dBu)” for no amplification or “Consumer (-10dBu) for an
amplification of the audio input signal.
Input Channel
Select which audio channels of the before selected Input Source (Line-IN) should be used
for the encoding, “Stereo” (both), “Mono Left” or “Mono Right”.
Sampling Rate
Choose the desired sampling frequency from the dropdown menu. Available for selection
are 22.05 kHz, 32 kHz, 44.1 kHz and 48 kHz.
A higher sampling frequency generates to more information, i.e. better quality, depending on
the bitrate you choose in the next step.
Encoder Type
Select the audio codec you will use for encoding, that is, either AAC or MP3.
Both are very common audio compression standards with a very good quality.
AAC is more efficient than MP3, especially for lower bitrates and the Variabe Bit Rate mode
– see next paragraph.
Bit Rate Type
Choose from Constant Bit Rate (CBR) or Variable Bit Rate (VBR).
A stream in variable bitrate usually requires less network bandwidth and could, theoretically,
have a better audio quality. The required network bandwidth for the stream depends from
the sent audio, e.g. voice needs usually less bandwidth than music.
In constant bitrate the stream uses always the same network bandwidth, independently from
the audio content, does matter there is voice, music or no audio. The advantage of CBR is
better compatibility with players.
Bitrate
Choose here the desired bitrate.
A higher bitrate represents better quality, but generates more network data.
Note:the available bitrates will change depending from selected “Encoder Type” and
“Sampling Rate”.
Note: make sure to have enough network bandwidth available, especially when multiple
listeners are connected to the Instreamer ICE over internet.
Server Type
Select here in which mode you will use the Instreamer ICE. Select “Icecast Server” when
the listeners should directly connect to the Instreamer ICE and listen the stream from its
built-in Icecast server. Alternatively, select “Icecast Source” when the Instreamer ICE should
feed a different, external Icecast server. Please see chapter 1.2 - Applications for the two
different modes.
Icecast Name
Configure here name of the stream. This name will be used in the metadata and shown to
the listeners, this could be for example your station name.
