DOLBY
קראתי את שרשרת המאמרים המקצועיים על תולדות האודיו הרב ערוצי, אך בשילוב עם דברים שקראתי באתרים אחרים נוצר לי בילבול. האם ניתן להגיד שהדולבי סטריאו היתה מערכת הסראונד הראשונה שכן על גביה ניתן היה לקודד גם את C וSUR. ואם כן אינני מבין מה ההבדל בינה לבין פרולוגיק.
אני חושב שאני יודע למה אתה מתכוון
דולבי סטיראו זה בעצם הדמיה של סראונד באמצעות שינוי של המיידע שמגיע מרמקול ימין ומשמאל

Dolby Prologic Virtual Speaker (Prologic 2)
With more and more people using computers and portable DVD players to enjoy DVD and other programming, Dolby Laboratories has come up with an advancement on their standard Prologic. The new system is called Prologic 2 (Prologic II). With this system there is an enhanced feeling of a true surround field utilizing as few as two speakers. There are two modes for Prologic 2 Virtual Speaker, Reference Mode where the distance between the front speakers sets the distance for the two virtual rear speakers. Then there is Wide Mode where the virtual rear speakers will appear to be farther apart creating a fuller sound stage in your listening area. For more technical details please refer to the Dolby white pages on the subject.
Prologic (Dolby Prologic)
This refers to a method of sound recording and reproduction developed by Dolby Labs to provide full surround sound. This is an active format that encodes the signals for the five or six speakers on two channels and decodes them during playback. Unlike regular surround sound the active matrix of Prologic provides a wider feel to the surround sound field. Features include:
High separation active matrix for enhanced directionality
Four output channels: left, center, right and surround
Automatic input balance control
Test noise sequencer for all modes
Surround channel time delay adjustable from 15 to 30 milliseconds
Center Channel control (Normal, Phantom, Wide) (see below)
