What’s up with the Beep driver in Windows 7?

Earlier today, someone asked me why 64bit versions of windows don’t support the internal PC speaker beeps.  The answer is somewhat complicated and ends up being an interesting intersection between a host of conflicting tensions in the PC ecosystem.   Let’s start by talking about how the Beep hardware worked way back in the day[1]. …

Windows 7 Reflections…

Today[1] Microsoft formally launched Windows 7.  I can’t say how proud I am of the work we did in Windows 7 – it’s been an amazing journey.  This is the 4th version of Windows I’ve worked on and I have never felt this way about a release of Windows.  I have to admit that I…

Win7 Whoppers

Wow, one of my co-workers just sent this image out.  It’s totally awesome (IMHO)… http://twitpic.com/mehp6/full     Edit: The image tag didn’t work for some reason so I removed it and just left the link… Bonus: The first Win7 ad: http://video.nytimes.com/video/2009/10/21/multimedia/1247465293593/an-ad-for-windows-7-from-microsoft.html#

Building a flicker free volume control

When we shipped Windows Vista, one of the really annoying UI annoyances with the volume control was that whenever you resized it, it would flicker.  To be more specific, the right side of the control would flicker – the rest didn’t flicker (which was rather strange).   Between the Win7 PDC release (what we called…

A quick run through the new Windows 7 multimedia audio SDK samples

As I mentioned yesterday, the Windows SDK is now live.  For the Windows SDK, there are 9 new samples (and one changed samples).    Two of the SDK samples demonstrate the WIndows 7 “Ducking” feature – they’re actually based on the code I wrote for my PDC talk last year, but tweaked to show some…

The Windows 7 SDK is live!

I just received email that the new Windows 7 SDK is now live!  Apparently it’s not on the Windows SDK download site yet, but if you click on the first link, you can download an ISO which contains the SDK.  For the Win7 SDK, I wrote about 8 new samples in the Multimedia\Audio category, they’re…

A few of my favorite Win7 Sound features – Stream Switching

Way back when I was in college, I learned Lisp using a derivative of Lisp called MACLISP (named for MIT’s project MAC, not for anything that came from a fruity company in Cupertino).  One of the coolest features that MACLISP offered was the (DWIM) command – basically if you had a typo when entering an…

A few of my favorite Win7 Sound features – Capture Monitor (aka Listen to…)

The capture monitor is a feature that allows you to listen to a portable media player (or any other microphone input) through your PC speakers.    First a bit of history.  Way back in the dark ages (Windows XP timeframe), audio solution manufacturers used to include an analog circuitry that connected the line in to…

A few of my favorite Win7 Sound features – UI refinements

Well, we shipped Windows 7, and now I’d like to talk about a few of my favorite features that were added by the Sound team.  Most of them fit in the “make it just work the way it’s supposed to”, but a few are just cool. I also want to call out some stuff that…
