Bug Squash: AlexP on MacBook Vista Audio Problems, Other Wifi Adapters and DPCs?

alexp_dpc

I love the sound bugs make when you squish them under a solution.

AlexP, whose blog is also a great source for multitouch and the Sony PS3 Eye Camera and Windows drivers we used in the recent hackday, has been diagnosing his MacBook under Windows Vista. Hardware problems are often the source of sound blips on computers. I’ve talked previously about using the DPC Latency Checker to find this issue.

The good news: Alexander has found the problem (the Broadcom Wireless Adapter in some Apple MacBooks) and a solution (switching off Windows’ automatic wireless network search when you don’t need it). I actually wonder if a similar problem was culpable in early problems with network WiFi on Mac OS X Leopard. Whatever is going on, check out the fix here if you’re encountering this problem. And let us know if you’re seeing this on machines other than just the MacBook revision F; I’d imagine any PC with a similar wireless adapter might have the issue:

And yes, hardware/driver problems may frequently manifest as what Windows terms DPCs – basically, a symptom of hardware usage that can interfere with reliable audio performance. I’m curious whether WiFi connections specifically may be a cause in other cases. The problem is almost certainly not limited to computers from Apple – especially since, in this case, the MacBook is just behaving like any PC laptop with similar specs.

Apogee Dumps Windows, Tells Users Macs are Better

Apogee Electronics has just announced they’ve dropped support development for Windows. Now, that’s their prerogative – not least because customers who prefer using Windows can simply choose to buy their competitors’ products. But in a press release entitled “Apogee Discontinues Windows Support,” “Apogee Discontinues Windows Development,” Apogee decides to tell you why, if you’re using Windows, you’re using an inferior platform.

Correction: Apogee just sent an updated press release.

ATTENTION ALL RECIPIENTS: Correction to Apogee’s most recent press release titled “Apogee Discontinues Windows Support”.

IMMEDIATE: Please revise headline to read “Apogee Discontinues Windows Development”

Guess Apogee is either reading CDM, or they just got some email about that subject header. And yes, dropping development of new products is not the same as dropping support for old ones, so this makes more sense (though the arguments I’m making about the tradeoffs between supporting platforms still apply).

Apogee Electronics will no longer develop products for the Microsoft Windows platform. Apogee has made this decision in order to focus all research, development, and support resources on the Apple platform with its unparalleled power and stability. Apple offers a wide range of affordable, powerful desktop and laptop solutions ideally suited for music creation and audio production.

This comes as no surprise, as Apogee’s interface line has already focused on the Mac. And, honestly, maybe that’s a good thing; the added focus could benefit Apogee as a small, boutique vendor.

More helpful advice if you are using Windows:

Windows users can obtain the Apogee sound by connecting Apogee converters to their Windows-compatible audio interface via AES, optical, or S/PDIF. Apogee technical support will continue to support legacy Windows configurations installed on Windows XP Service Pack 2.

Well, of course, that’s correct: if you’re just using Apogee for their converters, you can connect to Linux or FreeBSD or an Amiga or whatever you like, provided the audio interface itself has digital ins and drivers on your OS of choice.

Now, don’t get me wrong, I think Apogee is free to do what they want. It also doesn’t speak well for Windows – it’s a vote against Windows as a platform and the costs of developing for and supporting it. But locking yourself to one platform has dangers, too. Apogee invested a lot of time and resources into supporting their Duet FireWire interface, only to see Apple drop FireWire from their non-Pro MacBook line.

Anecdotally and statistically (in surveys and server logs), we see about 40-50% of you using Windows. So, whatever Apogee’s opinion of the Mac platform’s merits, I don’t see this as making that market any less relevant. In fact, I expect the handful of vendors paying attention to Linux, too, could have an edge as platforms evolve over the coming years. Apogee may be better off focusing on the Mac, but that leaves some opportunities for those vendors supporting PCs.

Optimizing for Vista: Inside the Mechanics of SONAR 8 with Cakewalk Engineering

On a purely technical level, how does Windows Vista work with a leading pro audio application? A lot of that depends on just how much the developer does to tune their software, and to hook into some of the new audio technologies in the OS.

I wanted to know more about how Cakewalk’s SONAR 8 DAW was specifically optimized for Windows Vista. SONAR 7 was already out in front with support for Vista’s audio plumbing, but SONAR 8 promises quite a bit more. With the help of CTO Noel Borthwick, we were able to go through internal engineering documents and communication and get the full story. (Noel, who has a resume as a Linux programmer as well as leading the top Windows audio developer’s technical efforts, has been very frank in the past about Vista, walking us through changes before launch and real world experiences one year later.)

As Noel puts it, this is “more minute detail than most sane people would care to read,” but that’s just the kind of detail we like. If you just want to know whether your software will work, this is overkill. But for those of you who, like us, are interested in why some things work, this is a good place to start. I also sincerely hope other developers on Windows will start to invest more time in some of these details.

If SONAR 8’s music features are what interest you, see our first look:

I’ll repeat my current recommendation on Windows. If you’ve got a system running XP and you’re happy, I’d stick with it. But I see no reason to avoid SP1, unless you have a specifically incompatible setup, now that SP1 and driver updates have brought some maturity to the platform. I find the new OS more usable and, with the right software and drivers, even more stable. (This is not what I would have said before SP1, especially early after launch.) In fact, this walk-through with Noel demonstrates why, in the case of a SONAR system, you might be happier under Vista, on a point by point basis. I’ll avoid the “versus Mac” or “versus Linux” arguments, as those tend to get more complex and abstract, but there’s some good stuff here for those of you with Windows experience.

And yes, if any developer would like to do a similar tour on the Mac or Linux, I’m all ears. But just in case you think I’m crazy when I say there is some really robust stuff for audio in Vista, now you’ll know just what I mean.

Adieu, XP; How Vista SP1 is Doing, and Why This OS Generation Has Been So Tough

XP passed into the shadows yesterday, officially — so how’s Vista for music? Some of the answers may surprise you. Photo: coda.

Yesterday marked the official phase-out of Windows XP. That in itself isn’t terribly big news; it’s easy enough to get XP systems for the foreseeable future, and custom builders can even put together an XP machine for you. Heck, you can even boot XP on an Intel Mac. But it seems like the perfect time to talk again about Vista. As with any OS, the branding (“we’ve got a new thing called Vista”) masks the more complex reality evolution of software and drivers. In other words, Vista today isn’t what it was the day it shipped. (That’s a relief.) And personally, I’d like to start talking about real-world performance and dispense with the kind of schoolyard rivalry the platforms have had over the years. I think it’s a safe bet to say none of us is excited about operating systems. We’re excited about actually making music. The good news is, Vista is finally looking like an OS on which you can do that.

The OS Generation Gap

>Quad-boot MacBook, by foskarulla.

It’s a funny time for operating systems and music applications, in that the most recent generational changes in Windows and Mac were unusually significant. On Windows, XP and Windows 2000 improved both audio and hardware support, and finally saw Windows NT really mature for music. On the Mac side, albeit slightly later, the bumpy transition to Mac OS X finally paid off as Tiger and Panther brought major audio improvements and reliability and performance enhancements. And Tiger got musicians onto Intel x86 CPUs, which helped unleash the live use of laptops we see today. Each of these updates came with compatibility hurdles, but there was a clear payoff. They’re must-have upgrades for music. Many music and audio apps won’t even work with earlier versions.
