People may find this very interesting..... the Pro Audio Spectrum 16 soundboard can play and record sound at the same time; as far as I know, this is the only commercially available board on the market that will do this. (Commercially available is important, because it means that people would be able to purchase said board cheaply, or perhaps alreadydy have.) So for roughly $200 US, and a little software, it should be possible to put together something that would do encrypted voice communications over the network. Is there any interest in developing some sort of standard protocol and software to do encrypted, compressed voice communications over TCP/IP? I can think some obvious design constraints right away; it should be device independent, which means it needs to be able to support multiple sampling rates, and negotiate sampling rates, in case one side as a limited range of sampling rates to choose from. It should support both multiple private and public key encryption algorithms, as well as multiple choicese of compression technologies. We'd probably want to have a core set of algorithms that everyone would be expected to support, for the sake of interoperability, and allow for people to experment with more powerful encryption/compression techniquese. And finally, for obvious reasons, at least one implementation should be developed in a non-COCOM country. :-) Is this something that people would be interested in working on? - Ted ------- Forwarded Message From: "Linux Activists" <linux-activists@joker.cs.hut.fi> To: "Linux-Activists" <linux-activists@joker.cs.hut.fi> Reply-To: "Linux-Activists" <linux-activists@joker.cs.hut.fi> X-Note1: Remember to put 'X-Mn-Key: SOUND' to your mail body or header Subject: Linux-Activists - SOUND Channel digest. 93-2-4-3:1 X-Mn-Key: SOUND Sender: owner-linux-activists@joker.cs.hut.fi Date: Thu, 4 Mar 1993 08:25:39 +0200 From: hsavolai@cs.Helsinki.FI (Hannu Savolainen) Subject: Preliminary GUS driver available Date: Thu, 4 Mar 1993 02:29:29 +0200 Hi folks, There is a very early testing version of the GUS (Gravis Ultrasound) driver available at klingon.epas.utoronto.ca (the GUS archive site) in directory pub/pc/ultrasound/submit. This version contains a simple API which makes it possible to write applications for GUS under Linux. Since there is no such applications yet, this is just a hacker's release. *** This is just a pre pre pre alpha version. I will release an official version after a couple of months. The official and supported version is 1.0 which you propably have already *** Additionally this version contains some changes for SB and PAS users. It is for example possible to record and play at the same time with PAS16 (there is a new devicefile (/dev/dsp1 (minor 19)), whic is connected to the SB DSP emulator of PAS. ...... ------- End Forwarded Message
