For home theatre enthusiasts, Akira on Blu-ray brings another true revelation to the table in the form of its soundtrack. For the first time ever, a digital movie soundtrack can be said to equal the very best the original master tapes have to offer. Recorded at an astounding 192khz/24-bit audio resolution - which is 4 times the sampling rate of a typical Blu-ray Disc - Akira's new Japanese TrueHD 5.1 audio takes up an astounding 12mbps of the BD's data rate all by itself! (For the record, that's almost as much as the video on Warner's Batman Begins Blu-ray). Without a doubt, this is THE audio Blu-ray demo disc for the foreseeable future. So for all those of you that received new speakers for Christmas... your holy grail BD has arrived. The English dubbed track was only created at 48Khz/16-bit, and retains that resolution in its own lossless TrueHD 5.1 presentation. Finally, the original Japanese theatrical mix is presented in LPCM, encoded as Dolby Surround. For longtime fans of the film, note that the Streamline dub is NOT included, quite possibly due to licensing issues, as MGM currently owns the Streamline assets through their acquisition of Orion. If getting the dub were even possible, it would likely be far more expensive than it's worth.

Sound:
Both the original Japanese track, now in a stunning Dolby TrueHD 5.1 mix, as well as the similarly excellent English Dolby TrueHD 5.1 mix, offer pretty close to reference quality audio. Akira is a riot of sound effects, from the opening nuclear explosion, to motorcycles roaring between channels, to Tetsuo's ultimate frightening transformation. Both of these soundtracks offer incredible separation and clarity, with a wealth of LFE and other ambient effect scattered throughout the channels. Dialogue is always clear and directionally placed. Also offered are Japanese tracks in PCM 2.0 and DD 5.1. English and Japanese subtitles are available.

If I could pick one area where this Blu-ray truly shines, it would be the audio. The default Japanese language track is presented in Dolby TrueHD 5.1 surround sound. There are also Japanese tracks in Linear PCM 2.0 and Dolby Digital 5.1, but I only spent a brief time with these inferior tracks. Getting back to the TrueHD track, this is easily the most noticeable improvement I’ve heard in the transition to lossless sound. It was as if a blanket was lifted from each of my speakers, and clarity took an instant jump. Spatial separation is dynamic, dialogue is appropriately balanced, and there was an unbelievable level of clarity throughout the film. This is one of those tracks that uses every speaker to envelope you in the on-screen action. A helicopter pan across the soundstage is appropriately loud, but never noisy, and the rumble of the film’s many explosions resonates with an oomph you’ll feel in your chest.
In the booklet included with the disc, there is a lengthy discussion of a theory known as the hypersonic effect, and how it was utilized in remastering the audio track for this Blu-ray release. I can’t say I understood everything included in the 10-page explanation, but I did find it interesting that the film's original composer, Shoji Yamashiro, is also a professor at the National Institute of Multimedia Education, and has published books on “Sound Ecology”. His studies have led to the theory of the hypersonic effect, and he was instrumental in remastering the high bit-rate TrueHD track for this Blu-ray release.
Rounding out the sound options is a Dolby TrueHD 5.1 track dubbed in English, which was on par with the quality of the Japanese TrueHD track.
