How Dolby TrueHD Works
Dolby TrueHD is a lossless compression audio format that enables bit-rate efficiencies (disc and transmission) for a file size that is half that of uncompressed pulse-code modulation (PCM), while simultaneously delivering a studio master–quality reproduction of the original audio performance. As a result, Dolby TrueHD enables the best-possible audio fidelity from Blu-ray Disc and from streamed or downloaded media sources.
