In the movie Alien: Covenant (2017)
WALTER: A rogue transmission, most probably. Your helmet must have picked it up because you were so far out... past our communication buffers.
Captain Oram: Is there audio, Mother?
MOTHER: Collating. A moment. I've reoriented the transmission, Captain Oram.
Another crew member: (distorted static continues... ) That would be an echo. The instruments took a lot of damage.
Would it sound better to say ‘must' instead of 'would'? Any differences?
