Speak Freely for Unix 7.6.a

Speak Freely is an application for Unix and Unix-like systems (Linux, FreeBSD, IRIX, etc.) with audio hardware, which allows you to talk (actually send voice, not typed characters) over a network. Speak Freely for Unix uses the workstation audio hardware and network to allow conversations of users over the network.

The phone company never gives you a break! You pay a fortune for a leased line connection to the Internet, and you *still* have to pay every time you want to chat with somebody, even though youre both sitting in front of workstations with digital audio capability, linked by a fast network. Speak Freely for Unix can intercommunicate with

Workstations on local area networks can generally communicate with excellent audio quality and response. A software implementation (developed by Jutta Degener and Carsten Bormann, Technische
Universitaet Berlin) of the compression algorithm used in GSM digital cellular telephones allows operation over Internet links of modest bandwidth. By using GSM compression in conjunction with sample interpolation, the data rate can be reduced to about 9600 baud. Users with CPUs too slow or two heavily loaded to perform GSM compression and decompression in real time may select less compact but quicker to
execute ADPCM coding, using an implementation developed by Jack Jansen of the Centre for Mathematics and Computer Science, Amsterdam, The Netherlands.
