AF(1)

NAME
AF - a network-transparent audio server and client library for networked audio devices.

SYNOPSIS

The AF audio server is a network transparent system developed at Digital CRL for using LoFi audio hardware in a distributed environment.

CONNECTION NAME

From the user's prospective, every AF server has an audio connection of the form:

hostname:portOffset

This information is used by the application to determine how it should connect to the server.

hostname
    The hostname specifies the name of the machine to which the audio device is physically connected.

portOffset
    The portOffset is used to identify the audio server's port on hostname. For example, to run multiple audio servers on a given host simultaneously, you need to select a unique portOffset for each invocation of an audio server.

If the connection name to an audio server is not specified, then the environment variables AUDIOFILE or DISPLAY will be used.

ACCESS CONTROL
The sample server provides two types of access control: an authorization protocol which provides a list of ``magic cookies'' clients can send to request access, and a list of hosts from which connections are always accepted.

BUGS
If you encounter a repeatable bug, please submit a problem report to () and include the source code if possible.

COPYRIGHT

Software in this distribution of the AF Audio Server is covered by copyrights. See the COPYRIGHTS file in the root directory of the source kit.

What you do with applications you develop is your buisness; if you wish to contribute code to this distribution see below.

In order to contribute software to the AF distribution, we suggest following the model of the X Window System. The following is the guide lines from that distribution. Other terms will make it unlikely that we will include a contribution on subsequent releases; we do not wish to spend our time with lawyers on a case by case basis.

The MIT distribution of the X Window System is publicly available, but is NOT in the public domain. The difference is that copyrights granting rights for unrestricted use and redistribution have been placed on all of the software to identify its authors. You are allowed and encouraged to take this software and build commerical products.

Individuals or organizations wishing to contribute software to the public releases should use a copyright notice that is no more restrictive than the sample given below. In particular,

o   Do not place any restictions on what can be done with this software (this includes using the GNU "copyleft").

o   Do not include the words "All rights reserved" unless you have had a lawyer verify that you have also explicitly given away all of the necessary rights shown in the samples.

o   Spell out the word "Copyright"; the phrase "(c)" is NOT a legal alternative to the c-in-circle symbol.

o   Put at least a one-line copyright at the top of EVERY source file, if not the full copyright. Also, the copyright line or full notice MUST physically appear in each file. Using the preprocessor to #include the copyright from some other file has no legal meaning (it can be used to incorporate common strings into the binary, but has no effect on the status of the source code).

o   Things that are copyrighted are, by definition, not in the public domain.

o   A copyright notice similar to the following is strongly recommended (replacing MIT with your organization's name and putting your name and address at the bottom).
