Op sommige films staat een track in DD3.0 Hoe is de setup voor deze track? Twee fronts en 1 achter?

Eigenlijk is dit gewoon dolby pro-logic.... Dus front + center speaker.

P.S. 1 achter wordt een beetje moeilijk, omdat er vaak een matrix signaal wordt gebruikt voor de achterkanalen.

Zo het is een beetje veel tekst, maar heb je er wat aan?
Helaas staat 3.0 er niet bij

Dolby Digital Surround This program features a matrixed surround soundtrack encoded to an AC-3 bitstream. When played through Dolby Digital equipment, sound will be heard from all five system speakers. The surround information will be monophonic.

Dolby Digital 5.1 This program features a discrete 5.1 (5 speakers + subwoofer) channel soundtrack encoded to an AC-3 bitstream. When played through Dolby Digital equipment, discrete sound will be heard from all five system speakers and the subwoofer.

DTS This program features a discrete 5.1 (5 speakers + subwoofer) channel soundtrack and must be played through DTS-capable equipment. When played through DTS equipment, sound will be heard from all five system speakers and the subwoofer.

DTS-ES The DTS-ES program includes the introduction of the new DTS-ES Discrete 6.1 format, which employs a new, proprietary technology for the playback of discrete, 6.1-channel content from DVDs and CDs. This latest innovation from DTS is the first of its kind, and it elevates the performance standard for playback of the DTS 6.1-channel Extended Surround format introduced in motion picture theaters last year.

Dolby Digital EX Dolby Digital EX is an enhancement to the very popular Dolby Digital. Dolby Digital contains a 5.1 sound format with 3 speakers in the front, 2 in the back/rear (called the surround), and a single bass unit. The EX adds a third channel to the surround giving a listener a 3 in the front, 3 in the back, and 1 sub listening experience. EX/ES sound formats are better than their 5.1 Dolby Digital and DTS relatives. Dolby Digital EX is also often referred to as Surround EX, Dolby Digital Surround EX, EX, DD-EX, DDEX, and Dolby Digital 6.1, which are all synonyms. Just the same, DTS ES is also DTS-ES.

Dolby Digital 3.0 bestaat niet!

Er wordt wel een logo gebruikt met 3 blokjes (2 voor / 1 achter) om Dolby Surround aan te geven. In dat geval is het signaal niet meer dan Dolby Digital 2.0 (twee frontkanalen) met surround informatie (surround geflagt) die via een matrix techniek uit de twee voorkanalen wordt gehaald.

En dan is er nog het betere DD4.0. Dit is dus surround geluid met discreet gebruik van de vier kanalen (achter is mono, geen LFE).
