As with the other Star Treks that I have reviewed to date, there is far less aliasing in this transfer than I would have expected given the clarity and sharpness of the image and the nature of the sets being photographed. There are a few minor film artefacts here and there, more than on previous Trek DVDs, but certainly not at any distracting level. It is a tad jarring, but not overly so. This is a superb, reference quality soundtrack. I listened only to the English soundtrack.
Dialogue is wonderfully clear and easy to understand, even at times of high ambient noise.
There were no audio sync problems noted. The music is by Dennis McCarthy , and whilst true to the Star Trek themes of the past, was relatively unremarkable. It was certainly suited to the on-screen action, but tended to force the emotional tone of a scene rather than complement it. The surround channels were highly active for most of this movie. Occasionally, they appropriately collapsed into mono for some dialogue sequences, but as a rule they had something to contribute to almost every scene.
