Dolby Has You Covered

From thunderous action effects to ripping bass chords to the subtle delicacy of a lone oboe, Dolby® TrueHD brings a palpable audio presence to the home theater experience. Dolby TrueHD is Dolby’s latest lossless technology, developed for high-definition disc-based media. The sound is bit-for-bit identical to the studio master, so listening at home is like being in the studio while the movie or video is being mixed, or at the sound board at a live concert. With Dolby TrueHD, the listener hears exactly what was captured during the recording and mastering process. Coupled with the high-definition video of Blu-ray Disc™, Dolby TrueHD unlocks an unprecedented home theater experience with sound as stunning as the spectacular picture.

Dolby TrueHD Features

• 100 percent lossless coding technology—with playback identical to uncompressed PCM
• Up to 18 Mbps bit rate
• Supports up to eight full-range channels of 24-bit/96 kHz audio*
• Supports up to 5.1 channels of 24-bit/192 kHz audio
• Bitstream transport enabled by High-Definition Media Interface (HDMI™ 1.3), the single-cable digital connection for audio and video
• Supports extensive metadata including dialogue normalization, dynamic range control, and downmix coefficients for 5.1- or 2.0-channel mixes as determined by the content provider
• Enables independent two-channel “artist’s mix” to be integrated into the Dolby TrueHD stream

*Dolby TrueHD can support more than eight audio channels. Blu-ray Disc standards currently limit its maximum number of audio channels to eight.
