Description
The configuration parameters include: codec, sampling rate, and bit rate.
Note: Setting the audio configuration during the 'play' state has undefined
results.
Syntax:
SEND_COMMAND <DEV>,"'SET AUDIO <codec> <sampling>
<rate>'"
Variables:
codec = Off, MP2, or MP3.
sampling rate = 32 KHz, 44.1 KHz, and 48 KHz. Sampling rate given in
KHz (KiloHertz).
Note: A sampling rate of 44.1 KHz MUST be entered as 44, using
44.1 will not work properly.
bit rate = 96 Kbps and 192 Kbps. Effective bit rate in Kbps (kilobits per
second).
Example:
SEND_COMMAND ENCODER,"'SET AUDIO MP2 48 10'"
Sets the audio configuration to use an MP2 audio codec sampling at 48KHz,
while transmitting at 10 Kbps.
Syntax:
SEND_COMMAND <DEV>,"'SET FORMAT'"
Variable:
format = NTSC or PAL.
Example:
SEND_COMMAND ENCODER,"'SET FORMAT PAL'"
Instructs the MAX-CSE to use PAL video format for the incoming video signal.
Syntax:
SEND_COMMAND <DEV>,"'SET GAIN'"
Variable:
gain = 0 - 99.
Example:
SEND_COMMAND ENCODER,"'SET GAIN 0'"
Sets the gain level to 0, which mutes the microphone. This corresponds to the
value seen within the MIC GAIN field on the A/V Setup UI page.
