NOTE:
The above command summary is only an abbreviated list given for example and

program. For detailed information on appTest program interactive commands, see the

4.3.5.2 RTP Audio Test Program
The RTP Audio test program is a WinXP program that:
receives UDP/RTP streams from the network and plays to the sound card (headphones or
speaker), and
transmits sound card input data (microphone) or waveform file data (.wav file) over the
network via UDP/RTP streams
The RTP Audio program can be set to work in different modes, including half duplex, full
duplex, .wav file data or microphone source, and with flexible RTP parameters, such as 16-bit
linear and 8-bit compressed payload formats and variable payload lengths.
Following are some command line examples.
1) Here the command line specifies source data as microphone and destination as a UDP/RTP
stream to IP address 10.0.0.53, using 8-bit uLaw RTP payloads:
-smic –d10.0.0.53 -u8
2) Here the command line specifies source data as a UDP/RTP stream received from a remote
PC with IP address 10.0.0.53, and destination as the sound card, using 16-bit linear PCM format
(also known as “L16”):
-s10.0.0.53 -dsnd
3) The following command lines set up an “RTP call” between two PC’s, allowing full-duplex,
real-time audio communication via UDP/RTP streams:
-smic -d10.0.0.53 -u8 -f
-s10.0.0.29 -dsnd -u8 -f
