You watch movies and TV shows on your PC. You use it to stream music. It's your game console and your videoconferencing center. Yet your PC has one major flaw, and that's its sound—tinny and weak at lower volumes, buzzy and rattling when you crank it up. Dolby Home Theater v4 solves the problem of PC audio performance with a suite of technologies that finally make your PC sound like the powerful multimedia machine that it is.
Dolby pioneered high-quality audio first in the recording studio and at the movies and then in the living room. Dolby Home Theater v4 benefits from decades of experience in areas like noise reduction, speaker optimization, and surround sound. It's a complete solution and improves audio performance whether you choose to listen through your PC's built-in speakers, your favorite pair of headphones, or by connecting your PC to a home theater system.
Understanding how Dolby Home Theater v4 works requires understanding the problems inherent in PC audio. These originate in both the quality of the source material and the playback process.
Typical problems with sources include:
The small speakers and underpowered amplifiers required to fit into the physical design of PCs create other problems. These include:
Designed into a PC, Dolby Home Theater v4 first applies processing that fixes any problems with the source material. It then fixes playback issues by compensating for mechanical constraints of the PC itself.
Because Dolby engineers custom-tune each PC model that includes Dolby Home Theater v4, the audio processing ensures that you enjoy optimal sound for the specific combination of speakers and amplifier in your PC.
