BARIX Instreamer - Encoding & Frequency; Encoding Quality

User Manual “Instreamer“ - V3.17 - 25th July 2011
Encoding & Frequency
Choose between six different MP3, 8 G.711 and 13
PCM encoding settings. The bit rate used for 8 and
24kHz G.711 and PCM is displayed in kbit/sec. in the
table below.
Encoding / Sampling
freq.
8 kHz 24 kHz
G.711 8bit (uLaw or aLaw) 64 192
PCM 16bit 128 384
For MP3 average bit rates see the next section.
Note: In case of S/PDIF input, if MPEG1 is used the
sampling frequency is auto detected (32, 44.1 or 48
kHz). For uncompressed formats the sampling
frequency must be set to match the input, the coding
type does not matter.
Encoding Quality
This parameter applies only when MPEG encoding is
selected in the previous parameter. Choose between
"0 lowest" and "7 highest" in steps of 1. The encoder
quality table below shows the average bit rate in
kilobits per second for the quality settings and
sampling frequencies in kHz using mono input with
MS-Stereo encoding disabled.
