Dolby Laboratories last week announced that Windows 7 will support Dolby Digital Plus to offer high-quality multichannel audio.
Available on the Windows 7 Home Premium, Professional, Enterprise, and Ultimate editions, Dolby Digital Plus will deliver home theater-quality audio to the PC.
The next generation of Dolby Digital, the multichannel audio standard for DVDs and select HD broadcasts worldwide, Dolby Digital Plus is a high-efficiency 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.
The Dolby Digital Plus audio format provides support for up to 7.1 channels and advanced features like bitstream mixing for secondary audio tracks. Dolby Digital Plus is also the broadcast audio standard for HDTV services in key countries including France, Italy, UK, Spain, and Sweden.
