Adding an RTP WAV Audio File to a Program

Including a WAV file stream in a program multicasts audio stored as a .wav file to listening clients.

Note that the sound format used to record the .wav file must match the format specified by Nsrtpaud.ocx on the client. For more information on specifying the sound codec for Nsrtpaud.ocx, see NetShow Client SDK. To check the sound format for a .wav file, open the file using Windows NT® Sound Recorder, and then click Properties on the File menu in Sound Recorder.

To add a WAV file stream to a program

1. Under Programs, click Manage Programs.
2. Click to select the name of the program to which you want to add the stream.
3. Point to New on the Stream menu, and then click RTP WAV Audio.
4. To give the stream a name and description, click the General tab.

   

   • In the Name box, type a name for the stream.
   • In the Description box, type a description for the stream.
5. To define the source and destination of the .wav file stream, click the Source/Destination tab.

   

6. In the File box, type the path and file name for the .wav file you want to multicast, or click Browse to locate and select a file.
7. In the Destination area:
   • Type the destination IP address in the IP Address box.
   • Type the destination port in the Port box.

     For more information on IP addresses and ports, see Setting Multicast Destination IP Address and Port in this document.

8. Specify the scope of the multicast by selecting a Time to Live option.
   • Click Local Network to limit the multicast to the local network node.
   • Click Intranet to limit the multicast to your site.
   • Click Internet to expand the scope of the multicast to the Internet.
   • Click Other to type a custom value. Values can range from 1 through 255.

     For more information on setting the scope of multicasts, see Setting Multicast Scope in this document.

9. To display the advanced options, click the Advanced tab.

   

   • In the Multicast Adapter Address box, select the address of the network adapter to use for multicasting on your server. If your server has only one adapter, leave default selected. On computers with multiple adapters, you can use this option to multicast separate programs simultaneously by using a different adapter address for each program.
   • To specify a length of time for the stream to run, click the Duration box, and then type the time in the format hh:mm:ss, where h represents hours, m represents minutes, and s represents seconds. When the time is up either the program ends or, if there is another stream following this one, the next stream starts. If no duration is specified, the stream plays to its end or until the program stops.
10. Click OK.
