Dolby evaluates DTS

[Paramvir Singh]

Introduction
Some audio industry members and consumers have compared Dolby Digital and DTS tracks on DVDs, and found that they sound different. Some say DTS sounds better. Until recently, it was difficult to prove or disprove this point, since DTS did not make encoders commercially available. Now that DTS encoders are finally being sold, Dolby has conducted a full set of measurement and listening tests on DTS technology.
Dolby's findings—combined with other research they have conducted—explain the differences some listeners have reported between Dolby Digital and DTS soundtracks, and reveal some interesting results.
