Windows 7 Gets Dolby Digital Plus Support

By - Source: Tom's Hardware US | B 26 comments

Now your new OS will know how to listen to surround sound signals.

Dolby Laboratories announced today that Windows 7 will have native Dolby Digital Plus support in the Home Premium, Professional, Enterprise, and Ultimate editions.

This means that playback of multichannel audio streams found in DVDs, HD DVDs, Blu-ray Discs and select HD broadcasts will decidable by the native software in the operating system.

"As Windows 7 amplifies the entertainment experience on the PC, it makes sense that Dolby Digital Plus is selected as the audio format for delivering high-quality surround sound," said Ramzi Haidamus, Executive Vice President Sales and Marketing, Dolby Laboratories. "With Blu-ray Disc, DTV broadcasts, and rich multimedia delivered through the Internet, Dolby Digital Plus ensures that people will hear outstanding audio on any device."

The Dolby Digital Plus is a lossy, compressed audio format that provides support for up to 7.1 channels and advanced features like bitstream mixing for secondary audio tracks. Now you just need something better than tinny computer speakers.

    I hope that I can afford Dolby 7.1 sound system. When will we have native THX support from Windows?

    That's nice I suppose. Of course most people building HTPCs that would use this are also using other software to support this, making it a little redundant.

    I guess it's just another reason for me to upgrade from XP. Not to mention that my original XP disc is so corrupted it can't copy half the files when doing repair installs...

    Hmpff, sweetness. I have a Dolby Digital Receiver sittin' right here next to me connected to my computer anyway. But, my soundcard already can send out a digital signal (bypassed) right to the receiver.

    THX isn't something that is supported. It is basically recognition of a certain quality of audio or video equipment. I guess a stand alone piece of software could possibly garner THX certification if it was superior in video or audio processing. We'll have to ask George Lucas. :)

    Could anyone give us a scenario in which the native OS support for Dolby Digital + is necessary?

    i'm confused, I don't have any media sources that have dolby digital plus format... I have lots of DVD format dolby digital sources, and a few dolby true hd sources from my blurays. but NO dolby digital plus sources...
    does this encompass support for the DVD format dd?
    does it mean windows will be able to output all sound as dd plus? (this seems niche anyway, as I'd rather lossless if i was outputting via hdmi anyway).

    if its JUST dd plus support, it is completely useless to me, and anyone except for those with a couple of HD-DVDs that use the format...

    (in aus, we are lucky to get dd 5.1 from DTV, does dd plus even work across spdif? or just hdmi? if it only works across hdmi, it is even more useless)

    Or, assuming you are using Firefox, just install the NoScript, and AdBlock+ plugins.

    NoScript is a pain at first as you add sites to your white list, but it's well worth it from a security perspective.

    I noticed that last week. WMP was the only player that would play AC3 audio with no problems. Didn't have to install any filters, nice that it worked out of the box. With ATI 4850 7.1 audio and Onkyo 705.

    Since win7 has built in dvd decoding (powerDVD not needed) you will have DVD playback with Dolby decoding without needing to add any additional software. No need for an A/V amp and speakers, just plug in your multi-channel speakers into the computer. Great for a kids room or anywhere else you don't need a full sound system.
