Unheard (2019)

This clever acoustic investigation strips away visual crime scenes, presenting only spatial floorplans and overlapping multi-room audio recordings of the past. Sleuthing requires pacing through the rooms with headphones, tagging voices, and cross-referencing character movements to unravel complex alibis and deceit. Because the audio plays simultaneously across different chambers, synthesising who did what demands patient deductive observation and meticulous timeline reconstruction.
