                      Internet Gopher Radio Hack

I. Overview of the Internet Gopher Radio Hack.

The Internet Gopher is a distributed document delivery service.  It
allows a neophyte user to access various types of data residing on
multiple hosts in a seamless fashion.  This is accomplished by
presenting the user a hierarchical arrangement of documents and by
using a client-server communications model.  The Internet Gopher
Radio Server and client allows one to listen to real-time digitized
sound across a network.


II.  Installing radio and radiod.

Since this is just a hack, refer to the Gopher client and server for
more information.

Currently the only platforms that this works on are sun and Next.

III.  Using radio and radiod.

First attach a source of live sound to a machine.  Now run the radio
daemon, "radiod".  (If you have a NeXT you will have to install the
play and record programs provided.).

Now type radio <hostname> <portnum> on another machine with audio
capabilities.  You should be able to hear what's being digitized on
the other end.

Hint:

To get the input level set right do the following on the server:

straylight% record - |play -

This will digitize and play on the local machine.
