“Hello people. I recently purchased new speakers (Acesonic 510 speakers)and a pioneer 819 av receiver capable of decoding TrueHD and DTS HD. Since my previous setup was only able to decode dolby digital and dts, how much better are the new formats? I imagine they are pretty noticeable considering the difference in quality I heard while comparing dts to dts 96/24. What are your thoughts about the new formats?”
Dolby TrueHD is Dolby’s standard for the Blu-ray disc format, which competes with the DTS HD Master Audio format in the high definition lossless audio world though they use very different technologies to achieve results. DTS-HD Master Audio is a combined lossless/lossy audio codec created by DTS (formerly Digital Theater Systems), commonly used for surround-sound movie soundtracks on Blu-ray Disc. It is difficult for you to tell the differences between Dolby TrueHD and DTS HD Master Audio by simply looking at their definition. Therefore I make a comparison between those two audio tracks here.
Part 1: What Is Dolby TrueHD?
Dolby TrueHD is a high definition digital-based surround sound encoding format that supports up to 8-channels of surround decoding and is bit-for-bit identical to a studio master recording. Dolby TrueHD is one of the several audio formats designed and employed in the Blu-ray Disc format, and, formerly in the now discontinued HD-DVD format. Dolby TrueHD is delivered from Blu-ray Disc, or other compatible playback devices via the HDMI connection interface.
Part 2: What Is DTS HD Master Audio?
DTS-HD Master Audio is a high definition digital surround sound encoding format developed by DTS for home theater use. This format supports up to 8-channels of surround sound with increased dynamic range, wider frequency response, and higher sampling rate than other DTS surround formats. Its closest competitor is Dolby TrueHD. Similar to Dolby TrueHD, DTS-HD Master audio is primarily employed in the Blu-ray Disc and Ultra HD Blu-ray formats, and has been used in the now-discontinued HD-DVD format.
