THX.. Hvad har det at sige?

Undrede mig bare. Kigger stadig rundt på diverse recievere, og falder engang imellem over THX processing. Hvad har det at sige når vi snakker lyd hjemme i stuen? Troede at THX kun var en standard for kvalitet, og ikke havde nogen decideret indvirkning på lyden.

Kigger jo på onkyo 805/875 vs. Denon 3808.. og det er fandme svært at vælge! Og det bliver ikke nemmere!

Undrede mig nu bare over at de bruger ordet "processing". Hvis det "bare" er en standard, så er det da lidt vildledende netop at bruge det ord.

Faktisk er det et godt sprgsm., synes jeg... Jeg har også en receiver med THX Ultra og tra-la-la... (Marantz SR-9200), men... undskyld hvis jeg spø'r dumt, HVAD skal man egentlig bruge det til i dag? De fleste dvd'er (nej, jeg har ikke BR) anvender da bare AC-3 (dolby digital) og DTS? ... jeg har ikke set dette kombineret med THX i MEGET lang tid... ta'r jeg fejl, så giv MEGET gerne lidt info og "lyd" fra jer..

...der er også et THX-logo på TITANIC-filmen fra 1997!!

 

Jeg fandt lidt mere info. Håber det kan bruges:

THX RE-EQ™

THX Re-EQ is a compensation technology taking soundtracks that are mixed for large cinemas, where speakers are placed farther away from you, and re-establishes the accurate tonal balance for your close range home theater speakers. Without THX Re-EQ, higher frequencies sound excessively “edgy” or “bright.” With THX Re-EQ, the movie soundtrack is true to the original immersive cinematic experience.

Example: The THX Certified DVD classic action film Aliens is loaded with audio and visual effects. When watching this film with THX Re-EQ activated in your THX Certified receiver or pre-amplifier, the technology adjusts and reproduces the high frequencies to play at the appropriate audio level in your home. Otherwise these frequencies would sound overbearing and distracting.

THX TIMBRE MATCHING™

Due to location, the tonal quality of the perceived sound coming from the side surround speakers is changed in relationship to the sound coming from the front speakers. This is because the outer ear, called the pinna, contours the frequency response of a sound depending upon its direction. The result is two conflicting sound fields - a front and a surround.

THX Timbre Matching technology solves this sound field problem by actually acting as an electronic pinna, restoring and integrating the perceived frequency match between the front and surround speakers. This technology allows you to be placed in the center of the onscreen action with smooth, rich surround sound.

Example: Imagine watching an aviation film with fighters traveling across the room. THX Timbre Matching accurately and smoothly pans the audio from the front speakers to the back speakers, ensuring consistent sound throughout the entire movie.

BOUNDARY GAIN COMPENSATION (BGC)

If you are sitting too close to a room boundary (or wall) your perception of the low frequencies is exaggerated. However, with the THX BGC filter applied to all output channels, the bass is equalized resulting in more true and accurate bass response.

Zaragon skrev: så lydsiden fra dvd er altså IKKE specielt enkodet?

præcis. Mange forveksler nemlig THX med Dolby Digital eller DTS, altså som et slags codec. THX behandlingen i receiveren er en efterfølgende behandling som ikke er afhængig af skiven.
