I.  Requirements:

    A.  Hardware:

    Since this software is a Java application.  You can run it on virtually any hardware platform.  I have tested the software for the following platforms:  SGI O2, SUN ULTRA, PC - Pentium 200Mhz.

    B.  Software:

    In order to run this application you need to have the following installed on your machine:
        VAT - Visual Audio Tool.  Try these links  Index of Mbone Software  or   Mbone Tools for Windows
        JDK - Java Development Kit  version 1.1.5.  Try this link  JAVA Products
        If you want to be able to record audio originating from outside of your subnet.  Your machine must also be able to accept IP multicast packets.  Here are some good links for informatin on joining the MBONE  the MBONE faq and  Dan's Quick and Dirty Guide to Getting Connected to the MBONE .

        You can run the program without MBONE connectivity.  But, you can only send multicast packets inside your local subnet.

II.  Instructions

    A.  Setup

        First create a subdirectory.  Place the file in that subdirectory.  Unzip the file.  This will create two subdirectories -- ver1 and ver2 along with the documentation files.

    B.  Starting the Application

        To start the application go to the following subdirectory


        Enter "java AudioPlayer1"

       You will get the following user interface.

    C.  Recording Audio

        First, in the filename field type the name of the file (ie audio.vat).  Next, type in the IP address, the port number.   At this stage, don't worry about the TTL field.  Next, type in the number minutes you want to record.  If you want to record until you press the stop button, type in "0".  Lastly, press the "RECORD" button.

        To stop the recording press the "STOP" button.


    D.  Playing Audio

        To play audio.  Start your "vat" application.  Note the IP address and port number you have chosen.

        Choose the "File" menu.  Then, choose "Open".  You will get a chance to pick the file you want to play.

        Next fill in the following fields:  IP address, port number and TTL.  The IP address and the port number should be the same as the one you used for the "vat" application.  The time to live (TTL) field determines the number of hops the packet will travel.  Use TTL of "1" to keep the audio packets inside your subnet.

        Press the "PLAY" button to start the audio.  Press the "STOP" button to stop the audio.

    E.  QUIT
