When virtual machine meets real machine...

In my previous post, I said,"As Gord pointed out, I am not sure you can record "real" music from a "virtual" machine."

Well, I did just that. I recorded while playing Carpenter's hit song, "Sing a Song" using GoldWave in a virtual machine (Microsoft Virtual PC XP mode which now has USB interface and it no longer demands that your processor need to meet virtualization requirements), and enjoy it in the real machine Windows 7 environment. It is cool!

Well, that makes total sense.

When a VM creates a sound card and plays it's output through the host OS, which in your case is windows, the vm host application pretty much just outputs as a wave stream....in Windows 7 it shows up as an application that outputs using wav because 7 changed the kmixer and such. But in XP terms...it basically outputs to waveout/directsound. For all intents and purposes, to the host OS the VM's audio stream is just an audio stream.

It works the same way for sound input...the VM hypervisor/host application basically polls the host OS's default input and routes that to x-input on the virtual card's input.

However, the USB funtion of virtualization solutions these days are quite nice. I have been able to use a USB card DIRECTLY in an XP VM, bypassing the host OS entirely.

I think people try to over complicate how they think VM sound works...when really the host OS treats it like an application...to an extent.

The Dell D830 under discussion is now available on ebay. Anyone interested in virtual machines can get my triple boot systems with two virtual machines ready to go.

Microsoft Windows 8 is scheduled to be released by the end of this year, but you can get a Windows 8 Release Preview free right now. Please visit Microsoft or CNET to download an iso image. Install your downloaded Windows 8 as a virtual machine and Windows 7 remains your host machine (real machine). Then you can install latest Goldwave edition in Windows 8. It will be interesting to see how GoldWave performs in Windows 8 environment. The beauty of this approach is that any bugs in GoldWave or Windows 8 will not affect your Windows 7 PC. You will be ahead of the crowd in testing new operating system. Anyone volunteer to do this?

As expected, Microsoft rolls out its Windows 8, Surface tablet and Windows 8 phone between last Thursday 10/25 and today 10/29. It will be interesting to see how well its new operating systems, tablets and phones are received. I checked Microsoft site for Windows 8 Release Preview, it is gone. Anyone knows where we can still get a free Windows 8 for evaluation purpose? If you can find one, you can still install Windows 8 as a virtual machine without changing your Windows 7 as a host machine.

Tablets to replace PCs in 2013, GoldWave goes portable

Talking about Windows 8 and Microsoft Surface tablets, we have to look at tablet world.
Microsoft is actually playing catch up in the crowded space of tablet world. Here are some bold predictions for 2013:

◦Mac sales growth will continue at 25 percent per year.
◦Windows 8 will bring only a small sales boost in 2012 as enterprises don’t rush upgrades.
◦Windows 8 tablets will account for 7 percent of all Windows PCs in the final quarter of 2012, jumping to 20 percent by 2013.
◦Yearly iPad sales growth will double this year and next.
◦Sales growth of Android tablets, including the Kindle Fire, will still lag behind the iPad, but sees 80 percent growth a year.

As a result, GoldWave Apps is not far behind, may be as early as 2014.

Windows 8: GoldWave seems to be working fine

I just installed 32-bit Windows 8 on an older notebook (Dell Inspiron, 3 or 4 years old). Windows 8 itself seems to be running fine; surprisingly quick, in fact, but it was running Vista before so I may have just been accustomed to it being a bit sluggish.

GoldWave installed and ran fine. The first time I tried to save a WAV as MP3 GoldWave offered to download LAME and that worked fine too.

The only downside is that Windows 8 seems to have taken away my Stereo Mix input. It recognizes the SigmaTel HD Audio drivers (the latest ones from Dell, and the same ones I used under Vista), and recording and playback work fine, but Stereo Mix is simply not there even though I have "Show Disabled Devices" enabled. (That's what I had to do under Vista.)

I'll fool around with some of the workarounds to see if I can revive it, but I'm not terribly optimistic. Oh well, that's the price of progress, I guess....

Great Gord,

I did not expect someone trying Windows 8 so soon. Thanks for sharing your experience. It is nice to know which one works and which ones don't.
