DTS Packer : Creating a DTS encoded file is a simple two-step process that requires the user to first create a packed agm file. The file is created using the Packer program that selects the individual audio files corresponding to each individual channel. The DTS Packer program generates a single agm data file from the multiple audio tracks. The user defines the Front channels, Back channels and whether the LFE (Low Frequency Effects) channel is used. Playback formats include 2.0, 2.1, 3.0, 3.1, 4.0, 4.1, 5.0, 5,1, DTS-ES 5.1 Matrix, and DTS-ES 6.1 Discrete.When encoding DTS-ES 6.1 Discrete channels the software requires 48 kHz or 44.1 kHz sample rates for the source files. Each of the active channels are displayed with the corresponding File Name, Sample Rate, Bit Depth and Track Lengh. If the Sample Rate defined by the user does not match the sample rate of the input audio file, a red outline will appear around the corresponding file Sample Rate. Also, if the file Track Lengh differs from any of the other input files, the corresponding file Track Length will also have a red outline around it as seen in our test case. The user can define the Frame Rate by selecting 24, 25, 29.97 drop, 29.97 non-drop and 30. The estimated output file size is also displayed at the bottom of the screen, which was almost 400MB in our test case with 5.1 96/24 channels. A 3dB Rear Channel Attenuation checkbox can also be selected by the user. When using an 88.2 kHz sample rate, the software only allows stereo tracks. Three bit rates that include 754 kb/s, 1.235 kb/s and 1.509 kb/s are available. Data sampled at 44.1 kHz or 88.2 kHz for multi-channel audio CDs must be encoded at 1.235 kb/s. Data sampled at 48 kHz or 96 kHz for DVD can be encoded at 754 kb/s or 1.509 Mb/s. The 1.509 Mb/s data rate fully supports 96/24 audio channels for superior fidelity. Once the files are defined, the user can select Pack or Pack and Encode to generate the agm file for the Encoder. The latter option automatically launches the Encoder once the packing is complete.
Once the packed agm file is created, the Encoder program is used to generate the DTS file. The DTS Encoder program accepts the single agm file created by the Packer program and generates an encoded DTS output file (wav, dts or cpt) defined by the user. The DTS Wave Format (wav) uses an Intel byte order and wav header. The Padded Format (dts) is a raw file with no header information and zero padding to fill frames. The Compact Format (cpt) uses a Motorola byte order with the timecode removed and a start time present. The cpt format is needed for the Apple DVD Studio Pro V3.0 software. The wav format is typically used for 5.1 or 6.1 music surround discs where no video is present. The dts and cpt formats are used for DVD authoring. DTS recommends users read the DVD Authoring for DTS document for those interested in creating DTS DVDs. Based on the source file packing options, the sample rate, channel configuration and bit depth are displayed. The user has the option of encoding the entire source file by checking the Whole Source File checkbox or a portion of the file defined by the Source Start Time and Source End Time. The user can set the Dialog Normalization value at this point to set the metdata used to control the playback level of the decoding equipment. It has no effect on the encode or decode process.
The DTS Pro Encrypter application is included with the DTS Pro Series Surround Encoder package and gives the user the ability to encrypt a packed DTS agm file. This allows the user to transmit the packed file over an unsecured network without worrying about it being intercepted by an unauthorized party. The software requires the user to enter a password consisting of at least eight characters. The process takes a little more than a minute to process depending on the speed of the computer being used. The same application is used to decrypt the encrypted file and is automatically recognized by the software based on the file extension.
