Mon Mar 15 06:04:51 PST 1993 This is a beta version of vat (the LBL audio tool) for the DEC 3max (5000 series) workstation. Please let us know of any problems, questions, suggestions, etc., via mail to vat@ee.lbl.gov. Vat requires the DEC CRL AudioFile audio server (available via anonymous ftp from crl.dec.com in pub/DEC/AF). While vat will work using point-to-point IP unicast, to get much value out of it you really should put IP multicast into your kernel (multicast for Ultrix is available for anonymous ftp from gregorio.stanford.edu in directory vmtp-ip). Vat should work with any audio device suported by AudioFile. In addition to vat, you might want to pick up Ron Frederick's nv video conferencing tool (available from parcftp.xerox.com in pub/net-research) and the LBL `session directory' tool (available from ftp.ee.lbl.gov:dec-sd.tar.Z). Remember, this is a beta version. Good luck. - Van Jacobson & Steve McCanne.
