This 11.5 Slashfilm article about Interstellar‘s bassy, soupy, dialogue-obscuring sound mix indicates that people are bitching about it all over the world. I was the first guy to complain about this (i.e., right after the 10.23 TCL Chinese elite-media screening), and a fair-sized percentage of HE commenters suggested it was because I have bad hearing. In any event today I heard from a venerated projection consultant about this issue, and he told me that a “qualified service technician” had applied a fix to the problem in a certain situation. He wouldn’t say what theatre or even what city, but here’s his report:
“On the subject of audio on Interstellar, I have been getting reports that the sound track is mixed such that the dialogue gets lost in scenes of dramatic sound effects,” he said. “This problem does not seem to be related to just the TCL Chinese. In one location the alignment tech boosted the center channel higher than [the] normal cinema spec to bring the dialogue up in relation to the Left/Right channels where most of the effects come from. This made the dialogue more prominent and therefore more distinguishable.
“Normally I would (and might still) argue against changing anything from established industry practices. In this case, I’m withholding judgment. My heart says he did the right thing, but my head tells me he did not.”
