Windows 7: Windows 7 Delivers Next-Generation Audio

17 Nov 2009   #1

Windows 7 Delivers Next-Generation Audio

When it comes to optimizing and really advancing the personal entertainment experience on the PC, Microsoft and Dolby Laboratories share a history of improving the integrity of audio playback. The collaboration between the two companies started when they began working together to enhance audio delivery for the Xbox in 2001. After this design was completed, Microsoft extended its usage of Dolby audio technology in Windows Media Center. This work continued with Windows Vista, which was launched worldwide in January 2007. The evolution of these shared efforts is realized in Windows 7 today.

Windows 7 builds on past collaboration by adding next-generation Dolby Digital Plus technology to offer high-quality multichannel audio. Available in Windows 7 Home Premium, Professional, Enterprise, and Ultimate, Dolby Digital Plus brings home theater–quality audio to the PC, improving the listening experience of music, movies, and TV.

When it comes to the small, discreet speakers built into a PC or laptop, how can audio really be optimized? Dolby Digital Plus, a multichannel audio standard for DVDs and select HD broadcasts worldwide, is a high-efficiency, next-generation audio codec that maintains the quality of Dolby Digital at a lower data rate and is fully compatible with all current Dolby Digital A/V receivers. From the movie and music producer point of view, this means that Dolby Digital Plus offers more channels and better compression, making it easier to create higher quality content at lower bit rates to experience on the PC.

Dolby Digital Plus is already the broadcast audio standard for HDTV services in Europe. France is currently using Dolby Digital Plus, with Poland and other countries following closely. Users in these countries watching streaming broadcast content on their computers get to experience next-generation sound.

Microsoft’s diligence in working closely with Dolby engineers to fully enable the PC to be a more sophisticated, dynamic entertainment device is evidence of the company’s broad vision and steadfast commitment to revolutionizing the role of the PC. The next generation of PC enthusiasts can enjoy their computers as their primary home entertainment device—and Dolby Digital Plus will play an important role in that experience.

Spinal Tap fans will recall the restaurant scene in which David St. Hubbins’s interfering girlfriend, Jeanine, informs the band that their album wasn’t “mixed right” because it wasn’t mixed in “Dob-l-ey.” We may be biased, but we tend to agree with that statement. Content is never quite right without Dolby audio technology. Fortunately, PCs with Windows 7 will never have that problem.

No offense, but..............

Yes, that great, but to take full advantage of it, you need to hookup an optical cable to your 7.1 channel home theater receiver.

I can't imagine playing it on regular computer speakers.

I'll be even more happy when they come out with Dolby TrueHD

Optical Cables cannot handle DD+. You have to use the Coax or analog direct to speakers or amp

An optical cable from the sound card to a home theater receiver sure will decode DD.

I use it all the time.

If you don't have a home theater connect, you still need at least 5 .1 channels to take full advantage of it.

An analog cable is not digital, so that would never work.

I think you have to pay for it also.

Analog to amp (5.1-7.1 out from the sound card) is most certainly digital. It has to travel from digital to analog at some point, this would be one step early.

DD+ does NOT travel on SP/DIF (Optical) DD DOES.

Trust me on this, I've been doing HTPC's and HD Media since HD-DVD first came to the market

That DD+ is PROBABLY going thru COAX.

BTW, COAX and analog are 2 different things.

Digital audio delivered from a Blu-ray or other digital media in it's original form, Such as DD+ or DTSHD in 7.1 is still digital audio.

If you have 7.1 speakers and a 7.1 out of your sound card, you are getting the true experience as long as you have the codec's that support DD+ or whatever on your player (PowerDVD or Set top box).

It doesn't matter what point it's converted to analog because it HAS to be converted to analog at some time to drive the speakers with the + and - charge to actually put out the sound that you hear.

Analog sound which you are probably thinking about is a monoral or stereo sound that is a traditional way to deliver music and movies on Dolby Surround.

One speaker per analog channel for digital surround is going to be the same effective output as hdmi

One optical cable will be the same as routing a red and white (Stereo) to your player

Now, Just in case you don't beleve me I pulled it from the Dolby website:
SP/DIF only gets 2 channel PCM

Dolby - Dolby Digital Plus

I didn't wanna make a fool of you or any of you. Next time I say something, take heed

Now, rep me! (Just kiddin')

Besides the fact that I've been using DD+ on my HD-DVD's and Blu-ray on my HTPC for quite some time, I have been an audiophile for all my adult and adolescent life.

My optical out from my sound card certainly does produce 5.1 channel sound on my Marantz receiver.

Totally false

Yes, I know what coax is, I have a monster Aka Reference Series integrated amp (when thee used to make good quality products) with coax in and out. I can record digitally to my mini disk player.
