MELP: 2400 baud speech coding
by John Gilmore 17 Dec '03

17 Dec '03

Mixed-Excitation Linear Predictive encoding gives better speech quality than CELP at half the data rate. Encoding and decoding together burn up more than 100% of a TMS320C3x digital signal processor at 33MHz -- 64% to encode and 53% to decode. I don't know how it does on a Pentium or an Alpha. If you have the MIPS at both ends, this enables very robust encrypted speech across modem links to the Internet. John Walker's free SpeakFreely software (http://www.fourmilab.ch/speakfree/windows/speak_freely.html; or follow the link from there to the Unix version) is already doing packet replication for high reliability, using the earlier LPC-10 algorithm. (It doesn't implement MELP, though those on fast CPUs could add it.) I noticed an ad in EE Times that said, "MELP: The new Federal Standard for 2400 bps Speech Coding", so I did a web search for it. It reportedly comes from Georgia Tech research. Atlanta Signal Processors has the exclusive license. See http://www.ti.com/sc/docs/dsps/softcoop/voc-13-1.htm. John Gilmore

Brock, you have probably heard by now -- this is wrong. The chip set was developed by a subsidiary of NTT called NEL.

LEGISLATIVE: SHORT NOTICE! of a SF SCTB/NRC crypto policy hearing
by Hugh Daniel 17 Dec '03

17 Dec '03

------- Start of forwarded message ------- Date: Fri, 31 May 96 18:12:00 EST From: "CRYPTO" <crypto(a)nas.edu> To: crypto(a)nas.edu Subject: Public briefing on the NRC Crypto Policy report Please post widely. The Computer Science and Telecommunications Board (CSTB) of the National Research Council (NRC) has completed a congressionally mandated study of national cryptography policy. The final report, Cryptography's Role in Securing the Information Society, was released to the public on May 30, 1996. Some members of the committee will conduct a public briefing on the report in Menlo Park, California at SRI International. The briefing will be held in the Auditorium of the International Building from 10 to 11 am on Wednesday, June.5. The address is 333 Ravenswood Avenue, Menlo Park, California, 94025. For more information about the briefing at SRI, contact Alice Galloway at 415-859-2711 (alice_galloway(a)qm.sri.com) If you have suggestions about other places that the committee should offer a public briefing, please let me know (crypto(a)nas.edu or 202-334-2605). A summary of the report ("Overview and Recommendations") is available through http://www2.nas.edu/cstbweb; the full publication will be made available when final printed copies of the book are available (probably around the beginning of August). If you wish to be kept informed of various other public activities regarding dissemination of this report, you can sign up for an e-mail list by visiting the web page http://www2.nas.edu/cstbweb/notifyme.html. I apologize to you for the short notice on this invitation, but hope that you will be able to attend.

What is wrong with this is that, because RSA did not, in practice deliver the software to NTT, they can have no expectation of payment. Thus begins a trumped up lawsuit in international court, and it will eventually cost RSA more to collect on the sale than the sale was worth. As many rock-solid implementations of the RSA algorithms as are out there, all NTT has to do is go to an FTP site in the netherlands. Done deal. But what about the copyrights (which are still unclear) and the US patents? NTT would not be able to market their system in the US without losing face. Not gonna happen.

Yes, I am sure Jim does. Expect a few Treasury agents to visit him in the near future regarding threats against the president, they seem to be a little overzealous about this statute...

A movement is not complete until it has a few nuts who claim you are not going far enough, only then does it have a chance of being incorporated into the mainstream. I would suggest just ignoring him, and once he is arrested claim he was a plant by the IRS :) jim

I'd rather see thousands of Internet-phone users transmitting at 2400 bps than 28.8 kbps... This is going to add to the telephone companies' woes: They obviously don't want people to have access to nearly-free Internet-LD phone service, but their arguments for its regulation will be weaker when it is pointed out that the bit rate for compressed, encrypted Internet phone are 2400 bps as opposed to 64,000 bps for POTS. Which raises another question: When are Internet ISP's going to start acting as Internet-phone gateways? Currently, you can't call somebody on POTS with Internet phone. This would be solved if ISP's could install modems and software which did audio-synthesis/digitization on an outbound call, driven by the data received on the Internet, and sending the data back to the calling end. Any guesses as to when this will be real? Jim Bell jimbell(a)pacifier.com

Seen on the net: AN EVENT AT COMPUTER LITERACY BOOKSHOPS ---------------------------------------------------------------------- CAN SECRETS BE STOPPED? ---------------------------------------------------------------------- A free presentation by Peter Wayner Ph.D. Date: Wednesday, June 19, 1996 Time: 6:30 p.m. - 8:00 p.m. Location: Computer Literacy Bookshops 2590 North First Street (at Trimble) San Jose (408) 435-1118 "Steganography" is the art and science of making information disappear. If you don't know where it is, you won't even know it exists. If you can't find it, you can't censor it. Dr. Wayner will explore some of the basic ways that people are hiding information by making it look like something else; such as innocent ramblings or flames from a newsgroup or background noise in a digitized image or sound file. Dr. Peter Wayner has a Ph.D. in Computer Science. He has worked at Xerox PARC and consulted widely on various topics, including computer security. His writing has appeared in popular fora like "BYTE" magazine and the "New York Times". He is the author of "Agents Unleashed: A Public Domain Look at Agent Technology" and "Digital Cash: Commerce on the Net" and "Disappearing Cryptography".

On the Hill: Child Porn "Morphing"
by Black Unicorn 17 Dec '03

17 Dec '03

Hearings on the hill over the child pornographer horseman: "Morphing" seems to be the latest buzzword for putting childrens faces on the bodies of adult models in sexually explicit poses and seems to have attracted enough attention to warrant congressional attention. Interesting that the media is playing this up as a "net" deal. (As if somehow it were impossible to do without the all powerful and evil internet. I'd like to see exactly how they word the proposed prohibitons. What constitutes "child" when the face painted on is pure artistry? Will we see a simple and strict prohibition over modifiying sexually explicit pictures to make them appear to be of younger models (whatever their apparent age may be)? Will we see a subjective test as to what is "child looking" enough? Silliness. All silliness. Prediction: Some manner of law will be on the books (Or perhaps passed, but unsigned) before the election attempting to prohibit some form of this activity. Certainly Clinton is not going to veto such a bill before the election, which is doubtlessly when the right is going to try to push it through.

Re: Java

I'll add a few comments about the "Java hype monster"... it seems a good way for people to make money off of computing in ways they haven't before (and in ways which probably won't work anyhow). A lot of the Java hype has been how one only needs a "network appliance" that logs in and uses remote applets which are instantly updated. Less risk of software piracy, more phone bills and network membership fees, of course. (Nevermind other risks added in this sort of system). It seems like a kind of cable-tv-for-the-internet. People will join a service that provides an array of applications. Network membership fees and phonebills... or maybe they'll use cable modems and it will be included with the cable bill on their JavaVision (tm) boxes? On the plud side, though: C never did standardize graphical interfaces. Notice most of the demos in the JDK are graphical? Rob. --- No-frills sig.
