Short: AmiTCP based voice chat program
Author: jfriesne@ucsd.edu (Jeremy Friesner)
Uploader: jfriesne@ucsd.edu (Jeremy Friesner)
Version: 1.3B
Type: comm/net
Replaces: comm/net/AmiPhone1.2B.lha
Requires: Workbench 2.04+, AmiTCP3.0b+, audio digitizer
AmiPhone1.3B:
This is a public beta release of my TCP/IP based voice chat software.
With it and a digitizer and microphone, you can transmit your voice
over the Internet or a LAN to another Amiga or Amigas that are running
AmiPhone.
AmiPhone uses ADPCM audio compression to allow transmission through
low-bandwidth connections. Thus, a conversation is possible even
over 14.4kbit/second modems. Of course, more bandwidth is desirable.
AmiPhone requires Workbench 2.04 or higher, AmiTCP 3.0b or higher,
and a Toccata board or standard parallel port style digitizer with
a microphone. Also, a fast CPU is highly recommended.
NOTE: AmiPhone is not compatible with I-Phone or any other
Internet-phone type program at this time.
NEW FOR AMIPHONE 1.3B:
- I've rewritten the net connection code so that it uses tcp
streams to connect to other Amigas. It also uses the tcp
streams to send control information, but it still sets up
and uses udp ports to send the actual audio.
Advantages of this new configuration:
. Connecting should be much more reliable. There is no
longer much chance of control information being lost,
since it is now transmitted over a reliable medium.
. AmiPhoned is much simpler. It no longer has to go through
a complicated song-and-dance to allow multiple incoming
connections at once. This is good, because apparently
some Amigas weren't very good at singing and dancing. ;-)
. Overall efficiency is not affected, because the actual audio
data is still transmitted via udp packets.
Disadvantages:
. This makes AmiPhone 1.3ß completely incompatible with
earlier versions of AmiPhone. On the other hand, the
upgrade is free, so this shouldn't be too much of a
hindrance to anyone...
. Your amitcp:db/inetd.conf and amitcp:db/services files
must be reconfigured again. The Installer script can
handle this for you, or look in the "Installation"
section of the .guide file for what the AmiPhone entries
in these files should now read, and change them yourself.
