DTS-formerly known as Digital Theater Systems, Inc.
Dolby-Dolby Digital is the name for audio compression technologies developed by Dolby laboratories.
Many home theatre and audio fans convince that DTS surround sound files have better quality sound effects than Dolby files. Because it has better dynamic range, more detailed subtle audio content and better signal-to-noise ratio.
People might think that DTS surround has a higher data rate when encoding than that of Dolby Digital and it list the associated formats.
It is understandable for drawing to this conclusion. People who support DTS think that they use of a higher bit rate and lower compression. However Dolby refutes with they are more efficient of codec. That is to say Dolby could achieve a higher compression levels for the same sound quality.
However, is it the truth? Let us see from the following aspects.
We can’t judge a sound quality just from raw bit rates and compression figures alone. The sound quality also depends on how well the algorithms are designed.
For both Dolby Digital and DTS Digital Surround system use data reduction techniques to remove useless data in PCM signal output. They remove audio data which can’t be heard to the human ear, so they make more space to store multi-channel sound. Both Dolby and DTS support 5.1 sound track playback and their performances are equally the same good.
To enjoy a high quality audio output, you need a not only a hardware support, but also a software support. Easy DVD Player software can output DTS and Dolby perfectly in your Windows system PC.
