Re: [LAU] CPUs for low latency

Comes with Linux drivers, controller and API if you want something different. But it doesn't compete with things like the 1818vsl with no MIDI and only 8 i/o at Line level. It does have lots of neat wizz bang stuff if you are doing audio mixing on the card... think playlist automation in a radio station (what it's designed for). In early computer audio days, the cost of a computer (desktop not ever laptop) was $2k ish (that could do much with audio) 300meg drives were some hundreds of dollars and you would need two to track very much. Most of the people getting into it already had at least an 8 track 1/4in open reel machine and (more importantly) a mixer with mic pres. They had already, even as a hobbiest, spent probably $5k minimum just to record on tape (and tape was $30 a reel too). The computer would have started as a sequencer that was more versatile than the QX7 (for example) because it could take one track and give 16 sounds at the same time (or 64 with the 401). So it was a limited entry deal. It was some time after that with gigabyte plus hard drives for less than $200 and faster computers for less than $1000 that it was possible for people to get into the game with an internal card (AudioPCI, Soundblaster or knock-off) and a game port. That let a lot more people in. Todays PCs are way cheaper and the laptop is pretty much as capable as the desktop. There are a lot more people doing music with computers and a great percentage are using entrylevel stuff. Laptop, now means USB is the only expansion game in town... The manufactures have worked hard to make it so. Even many desktops are hard to expand... and besides that, many fewer people (percentage wise) are willing to take two screws out of the cover to actually change something inside. For less than $500 one can have the computer and USB mic and make music. Manufactures do not want to make two kinds of audio boxes if they can make one... the USB box works everywhere. Raise latency a bit and it just works (even in windows). Raise the latency a bit because USB requires it, because we don't want complaints from the owner of the "super computer" buyer who has a very fast machine with 32 cores and 64GB ram and poor latency. So really, the USB IF fits in with everything else pretty good. (It is the best compromise for the market) Has anyone noticed that mother boards still have a printer and two (or four) serial headers? -- Len Ovens www.ovenwerks.net
