Nearly all Blu-ray players will support Dolby TrueHD and most will also now support DTS-HD Master. Most Blu-ray discs will have one of the sound formats on and some even older films will have been remastered and ‘cleaned up’ to remove hiss and drop outs and to take advantage of the lossless storage. To hear either Dolby TrueHD and DTS-HD Master you will need either a Blu-ray player capable of decoding both formats, or a home cinema amplifier that can decode a bitstream signal sent from your Blu-ray player, and an HDMI cable to specification 1.3a or above (most are these days).Īlthough each format has various specialist sub types, the two main formats are:ĭeveloped by Dolby Laboratories, Inc offers a bitrate of around 18Mbps which is a massive 36 times more than the standard Dolby Digital bitrate of just under 500Kbps.ĭeveloped by DTS (Digital Theater Systems) it offers a slightly higher bit-rate than Dolby TrueHD at just over 24Mbps so can offer slightly more sound data per second, which is twelve time more than the standard DTS signal. In a similar way to their standard definition counterparts ( Dolby Digital and DTS), the difference between them is minimal whilst the final sound mixes may alter slightly with each movie, they are both extremely good at reproducing a very high quality sound.
Maximum Quality – Just like the Director intendedīoth formats are capable of storing completely lossless data, so the final sound you hear is exactly as the film studio and sound engineer intended, and have not been compressed, or reduced in quality in any way. Also, go into the GENERAL configuration and look at the INFORMATION/AUDIO section to determine exactly what is coming into your receiver.Ĭonventional 7.1 DTS-HD MA encoded audio would not engage the ceiling speakers without you applying Neural:X or Dolby Surround upmixing to it.When considering a modern home cinema system you will more than likely want to take advantage of everything the new high definition video and audio formats have to offer, and have probably heard Dolby TrueHD and DTS-HD Master surround sound mentioned, but what are they, and what can they offer you as the home cinema buyer?ĭolby TrueHD and DTS-HD Master are both high definition multi channel sound formats developed for the new high definition Blu-ray, and the now defunct HD-DVD discs. What does it say on the front panel of your receiver while receining the audio in question. Are he ceiling speakers still being engaged? What happens if you ngage the receiver's PURE DIRECT mode. Here a table chart is presented below for you to tell the differences between Dolby. Part 3: Dolby TrueHD vs DTS HD Master Audio. If on the otherhand you are receiving DTS:X encoded audio while Dolby Surround is engaged then you'd not get DTS:X and you'd only get DTS-HD Master Audio with Dolby Surround upmixing. 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.

If you wer to apply Neural:X to Atmos encodd sourced, the receiver would ignore the Atmos metadata and give you DTS-HD Master Audio plus Neural:X upmixing. The metadata is sent within the formatted audio's package. It should however be noted that Atmos metadata is conveyed to your receiver alongs with Dolby TRueHD or DD+ audio and DTS:X metadata is sent with DTS-HD Master Audio encoded audio. The additional speakers are only used if you are either receiving Atmos or DTS:X encoded audio or if you are engaging Dolby Surround or Neural:X upmixing.

IN most instances apart from an Apple TV or an XBOx this would mean configuring the source to bitstream its digital HDMI audio output. IN these instance the presence of the metadata would negate the upmixing and bypass the associated processing.Īlso ensure that the source is conveying the audio to your receiver via HDMI and that the source device is correctly configured to output Atmos and or DTS:X. THe caveat to this is if applying Dolby Surround to Atmos or if applying Neural:X to DTS:X encoded audio. If the source is supposed to include Atmos or DTS:X then you'd get this as long as you aren't apply additional upmixing to it. THe height speakers will not be engaged with such sources unless you engae one of the upmixing options. If not wishing to engage Dolby Surround or Neural:X upmixing then the best you'll get from any older content not inclusive of Atmos or DTS:X is 7.1 mixed down into the 5.1 lower level speakers and nothing would be portrayed via the 2 height speakers.
