While the audio across the dynamic range is delivered in good detail, with plenty of resolution, the Dolby TrueHD content is clearly bass-heavy. It doesn't have quite the 3D impact one might expect in an action movie, with very little content assigned assigned to the rear channels. But it is preferable to err on the conservative side than to have an overly aggressive surround soundstage where it is really not warranted. On the other hand, some multichannel audiophiles may nitpick that the surrounds are underutilized. The anchoring across the center channel delivers all the dialog, while the front left and right speakers provide the bulk of the score. The music by Hans Zimmer and James Newton Howard is less thematic and more of a mood amplifier to make the story more hard-hitting. Aside from the sound effects and subwoofer content, the soundtrack mostly disappears in the action and visuals. Looking back on it, that is a unique accomplishment for an action film, to be such a visual work of art that one hardly notices the score as sound. While all detail of the dialog and music is clearly articulated across the front channels, it often sounds diminutive in comparison to deeper content.
Listen to the scene where Batman, Lt. Gordon and Dent have a rooftop meeting together. Gordon's and Dent's voices are perfectly reproduced, crisp and detailed, yet they sound slightly anemic compared to Batman's deeper, more open voice. While the audio engineering is actually very good, the bass emphasis can overshadow the more relaxed dialog, especially Gordon's voice. This is a minor complaint, as all dialog is plainly audible and every word and breath expertly recorded. And of course, the advantage of having a pronounced LFE channel is on display throughout The Dark Knight. Listen to the scene where the 18 wheeler flips over its horizontal axis--an impressive bit of stuntwork--creating a cacaphony of deep bass rumble, crashing steel and other sound effects. Explosions, breaking glass, gunshots and other effects are impressively engineered. The amazing feature of the Dolby TrueHD track is that nothing gets lost in the mix, regardless of the minimal use of surrounds. One of the denizens at
Blu-ray.com asked whether Warner's BD defaulted to the Dolby Digital track, as many of its titles do. The answer is yes. It is imperitive to go into the menu immediately when the movie starts and select the TrueHD track.
Transformers: Revenge of the Fallen Blu-ray, Audio Quality : 5/5 Does this section really require analysis? Transformers: Revenge of the Fallen's DTS-HD MA 5.1 lossless soundtrack is terrific,
quite possibly the best currently available on Blu-ray. The studio logo sequence alone is of reference quality; the Paramount stars sweep through the soundstage from front to back with a digitized, robotic sound, accompanied by a nice low-end presence and fully-engaged rear-channel activity. Bass is positively tight and robust throughout; the entire theater shakes with every heavy robotic footstep, gunshot and explosion, and percussion beat of the score. Gunshots zip across the soundstage, explosions push objects from side to side through the listening area, and voices echo about a tomb in chapter 14, all to startlingly realistic effect. Distant explosions and sound effects, particularly in the film's Egyptian combat sequence in the final act, do a superb job of placing the listener in the midst of the desert and the action. What's so amazing about this soundtrack isn't just that it features room-shaking bass and fully-realized surround activity. Instead, it's the seamlessness of it, its ability to draw listeners in and create a virtual world of sound where the home theater transforms into a space hosting a running gun battle, a bustling college campus, a wooded area engulfed by the destructive power of stories-tall robots, or an Egyptian desert devastated by brutal warfare. The faultless dialogue reproduction seems a mere afterthought, but it's the final piece to a perfect soundtrack.
