The Interstellar soundtrack features a combination of electronic and orchestral elements, creating a unique and haunting sound that mirrors the film's visually stunning depiction of wormholes, black holes, and distant planets. Hans Zimmer's masterful composition has been widely praised for its emotional depth and innovative use of sound design.

Zimmer famously chose the 1926 Four-manual Harrison & Harrison organ at Temple Church in London as the "heartbeat" of the film. In tracks like "Cornfield Chase" and "No Time for Caution," the organ produces deep, sub-bass frequencies and complex overtones. Lossy formats often "muddy" these frequencies, but in FLAC, the bass remains tight, textured, and physically resonant. 2. Dynamic Range
