On the AUDIO CODING page, the coding
algorithms are set when the operating mode is set
to IP LEASED LINE STANDARD / EXTENDED.
▪
CODING ALGORITHM: Select one of the installed
codecs:
G.722, PCM, OPUS, FLAC, MPEG (some optional).
▪
MONO MODE: Select how the audio input signal is
▪
used when the algorithm is set to mono:
▪
MONO LEFT: Only the left channel of the input
signal is used.
▪
MONO RIGHT: Only the right channel of the input
signal is used.
MONO (L+R)/2: Left and right channels of the input
▪
signal are mixed.
▪
ANCILLARY DATA (PAD): Some codecs support
transmission of data along with the encoded
audio within the stream. If enabled, the device
routes data provided via the DATA Interface
(RS232) to the encoder. The data rate used for
PAD reduces the data rate of the audio signal.
Audio Coding (2)
▪
ALGORITHM: If the MPEG codec is selected, you
can choose between the available variants here
(some optional):
L2: Layer 2 (MP2)
▪
L3: Layer 3 (MP3)
▪
▪
