I'm familiar with 100 Mhz 32b MIPS cores that cost about $10 and include 2 ethernet i/faces. Intended for cheap SOHO routers, etc. Newer variants include IPsec support (e.g., a DES engine) for the same price. They'll run Linux. ARM's advantage is in power consumption, AFAIK, which doesn't always matter. I can see other reasons for hacking an answering machine ---encrypting stored messages, implementing/augmenting your own DTMF decision tree, allowing some to leave longer messages than others, even machines that call another number to forward. (I once worked on a commercial system that implemented a POTS i/f as boards in a Wintel machine, its (perhaps now extinct) niche was cheapening international phone calls.) Cheapo fax/soundcards are able to do ring detection, pick up, etc. Probably a fun project, the POTS i/f won't go away soon.

"Then your ears are not golden, period." Harumph! But you misunderstand what the phase button does. If the speakers are wired out of phase anybody can hear that. Actually, it's a quite interesting thing to hear...nothing is really localizable. But the phase button inverts the absolute phase of the signal coming out of both speakers. In other words, with a bass drum hit do the speaker cones move outward at the initial strike or inward (as they are not supposed to). Supposedly this difference can be heard, but my speakers start rolling off below 100Hz, so I suspect that's why I have a very hard time discerning the absolute phase difference when I hit the button. -TD >From: Jim Choate <ravage(a)einstein.ssz.com> >To: <cypherpunks(a)einstein.ssz.com> >Subject: Re: Idea: The ultimate CD/DVD auditing tool (meow) >Date: Wed, 9 Jul 2003 23:51:47 -0500 (CDT) > >On Wed, 9 Jul 2003, Tyler Durden wrote: > > > Somebody wrote... > > > > >Yes this is for localization ---clicks are broadband, you need to > > >identify which freq components are used.

A couple of corrections, then the comment. First is that tubes boost the even order harmonics, making the sound much richer and fuller sounding. Also, the Krell is digital, not tube. But your point is correct, but also well-known within audiophile circles. In fact, single-end triode style tube amps (which hit the market about 10 years ago) have really rotten measureables, but they have continued to grow in popularity because of the the allegedly "live/lush" sound. (Another odd thing about them is that they have extremely low output powers--12W, 8W and 6W are common!) Everyone knows they are basically nearly random tone-control gizmos, but no one cares at this point. As for 24/96 (or 24/192), like I said there are real engineering reasons for doing this, but in the end there's not much reason to argue if you haven't heard. Go listen to a standard CD played on an upsampling machine and you will know in no uncertain terms that the sound is considerably better/fuller/realler. (A hint as to why can be seen when you look a square wave reproduced in 16/22 vs 24/96.) As for audiophile voodoo there's a lot out there, but there's a pretty easy way to differentiate voodoo from real (though 'inexplicable') high-end stuff. The voodoo dissappears within a year or two, but the real stuff keeps going. -TD A PS about double-blind: There's been lots of them done, some confirming audiophile expectations some contradicting. Some of the disparity is due to who the blindees are: high-end listening is a skill that is basically self-taught. Some of the high-end tweeks have differences that are not discernable to nonGolden ears (and some tweaks are obviously pure snakeoil). _________________________________________________________________ Add photos to your messages with MSN 8.
