Mr White's "Opus", designing a simple balanced DAC

Perhaps someday. but there is so much on my plate right now I would not hold your breath.

Oh i know what it is like... we are finally shipping betas of the Frugel-Horn flat-pak -- that only took since last Sep to get together

PS. Have you looked at fixing your web site yet? Works in FireFox (3rd string browser), it crashes Safari (2nd string), and iCab (primary) gives the attached error but none of the navigation links work)

[planet10]

I'll have to ammend the PS: Safari doesn't crash. It comes back after about 15 min, and then takes what seems a similar time to load a page when clicked on.

This apparently only happens on the MAC, and I don't have one to test with. If you can get me some more detailed error messages (what script is having issues, etc) it would be most appreciated. I might try to borrow a Mac from a guy at work to figure it out...

[planet10]

It is more likely a browser specific issue -- javascript is guaranteed to break somewhere sometime as there is no standard. And with the wide range of browsers people use on the Mac they are just more likely to run into them.

I don't know enuff about using the javascript debugger in iCab to get much meaningful for you, but this might say something....

The error reporter also shows a number of CSS & HTML errors. Mail me and i'll do what i can to help you debug it. Personally, i just never use javascript.

Bingo.

wz_tooltip was causing the problem a while back so I wrote my own tooltip code, but i guess i forgot to delete the ref. Should be fixed now. Thanks

[EDIT] sorry for the OT chatter

[planet10]

That got rid of the long wait for the loop to complete. Main page loads in promtly. In iCab the menus for navigation still don't work -- they don't even show up in the status bar (they work in Safari)

In the code they look pretty much like standard html links (except for the class thing). I'll email Alexander (the 1 in the 1.5 developers for iCab) -- he'll be interested and might be able to shed some light.

You scraped the coax, so you can also scrap the 75 Ohms.. I guess it would be better to leave the as-is. Oh well, for that short distance, it probably doesn't matter that much anyway.

While Firewire is great as a standard, is really sucks when it comes to audio chips, let alone drivers for it. The USB stuff, you just plug in, and your ready to go. No need for any drivers, and it works on windows, OSX, en linux. Great fun!

I agree, fire-wire is for speed/data intence hardware. A audio device such as a DAC will never even closely use the amount of bandwidth need that Fw400-800 can supply.

Usb is just fine, plus there are more supported chip's. ie plug'n play.

Firewire in Audio is important because of it's low latency compared to USB more than it's transfer speed. Admittedly it would be of little use in this specific application, but for multichannel recording and playback in a studio environment it's indispensable. Also, USB doesn't work well in certain measurement applications because of the polling latencies.
