DTS-HD Master Audio Decoder:  DTS-HD Master Audio Decoder

DTS-HD Master Audio is a lossless extension to the core DTS 5.1 surround format. It is used on Blu-Ray video discs to allow bit-to-bit accurate reproduction of the original studio master. The standard reproduces up to 7.1 audio channels at 24-bit resolution and 96kHz sampling rate. The nature of having the core and extension components allows the DTS-HD MA stream to be decode-able on non DTS-HD capable equipment where only the core 5.1 lossy component is decoded.

Average Average Peak
ADSP-214xx 117 147.1 131.0 184.2 196.9
  • MIPS measured using a lossless encoded MA bit stream at 192kHz and 7.1 output with PBR smoothing running on a ADSP-21469.
    Note that the Bluray specification only allows DTS-HD MA with 5.1 output at 192kHz.
  • Averaged Peak MIPS have been measured using a four-frame moving average.
  • Code compatible across all ADSP-214xx processor
  • "Data RAM" for one instance, includes Stack, Scratch, Instance/State, minimum input and output single buffers
  • Input buffer size is 32 KiB and output buffer size is 32 KiB
  • Frame size considered is 1024 samples per channel
  • 1 KiB = 1024 bytes
