You can do the last by dragging and dropping files onto the appropriate filename boxes, or from the navigation window that opens when you doubleclick on the empty filename box. Then you select the speaker layout that was used to mix the files to be encoded, set the sample rate for the stream, and import the source files to be encoded. You can set the Destination Format (Bluray, HD DVD or DVD) from a dropdown menu to suit the various formats, along with the desired format for the stream. The current version 1.5 runs on Windows XP and on Intel Macs only my tests were done with v1.1 on a Power PC Mac. This last replaces Neyrincks Soundcode DTS StreamPlayer plugin, which was bundled with older versions and is still available from Neyrinck themselves (see Soundcode DTS StreamPlayer box). There are three components to this suite: DTS Encoder, DTS StreamTools and DTS StreamPlayer. The DTSHD decoder then takes the lossy Core Stream and the HD Master Audio stream, and combines them into an output that is identical to the original uncompressed studio output.įor example, if an end user has a Bluray drive in a Sony Playstation 3 but hasnt bought a new audio receiver with the new decoders in it, he or she can still view the HD content using an HDMI connection to their highdefinition screen, while taking the digital audio stream from the Playstation 3 and decoding the 1.509Mbps Core Stream to get 5.1 surround audio at 48kHz. The HD encoder takes the Core Stream, compares it with the uncompressed input, and produces a difference signal made up of the information that was thrown away by the lossy compression. This uses a stream of up to 18Mbps for the HD DVD format or up to 24.4Mbps on the Bluray format. The introduction of highdefinition DVD formats such as Bluray and DVDHD means there is space for even higherquality audio options, and so DTS have added two further extension options to their format.
These are DTSES, which offers 6.1 by adding a centre surround channel, and DTS 9624k, which is still 5.1 but with a maximum sample rate of 96kHz. However, DTS have also designed extensions to deliver extra levels of quality.
