DTS (Digital Theater System)

An audio format that competes with the similar Dolby Digital. The DTS (Digital Theater System) format uses less compression than Dolby, so theoretically it sounds better. The DTS encoding algorithm was originally designed exclusively for 5.1 multi-channel audio. Unlike Dolby Digital, where some channels may not be in the stream at all, in the DTS stream. There is always a place reserved for all six channels, and if there is no real information in them, this place simply disappears. That is, with the same bitrate in DTS, a 4.0 recording will be the same volume as 5.1.

Difference between DTS and Dolby Digital

  1. The main differences are in the degree of compression and bitrate values. Dolby Digital compresses 5.1-channel digital audio up to 640 kbps for Blu-ray discs and up to 448 kbps for DVD.
  2. DTS has a lower compression and higher bit rates, up to 1.5 Mbps for Blu-ray discs and up to 768 kbps for DVDs.
  3. The difference in compression becomes even greater for formats in HD. Dolby Digital Plus supports up to 1.7 Mbps and DTS-HD High Resolution up to 6 Mbps. Theoretically, a lower level of compression during encoding provides more detail in the result, making the audio track more like what was intended.

What is DTS-HD High-Resolution Audio?

This type of format implies a superior audio signal with a fixed value (minimum 1.5 Mbps – maximum 6.0 Mbps for Blu-ray Audio and 1.5 Mbps to 3.0 Mbps for HD- DVD CD). It can provide up to 7.1 channels of audio at a sampling rate of 96 kHz. The depth is 24 bits. DTS-HD High-Resolution Audio has been selected as an optional specification for HD DVD and Blu-ray Disc. The format can also be a good alternative to DTS-HD Master Audio when disk space is no longer enough

What is DTS-HD Master Audio?

This format was known as DTS++. DTS-HD Master Audio allows you to keep the sound identity (literally bit-mapped) of the original. In addition, this format can transmit an audio signal with the highest possible bit rate with lossless compression of 24.5 Mbps (this is for Blu-ray discs) and 18.0 Mbps (HD DVD).
Supports up to 7.1 audio channels. The bit depth is 24 bits, and the sampling frequency is 96 kHz.
