Changes for the game: selected recordings were cropped, resampled, segmented, and in some cases looped with crossfades. Two train loops use constant 0.5 gain. The supplied map opening and closing files were cropped to 0.10–1.10 seconds.

Video audio is the actual Unity main mix, including spatialization and gameplay cues, recorded through AudioRenderer and encoded to AAC. The trailer cuts the recorded sound together with the corresponding shots and mixes it below the separately credited music. The gameplay uses no added music. Minor end padding completes the fixed video duration. No endorsement by these creators is implied.
