Sound designer Mira Deshpande came home to restore her grandmother's tapes. She found something else underneath them. Beneath sixty years of family recordings runs a frequency that was never in the room — a 19-hertz tone, identical across decades. When Mira plays it back, something answers. In her grandmother's voice. The house has been broadcasting for sixty years. It speaks only in borrowed voices. It travels inside recordings. And silence — the one thing that starves it — is the one thing Mira can no longer afford. A slow-burn folk horror about grief, sound, and the voices we keep. Dead Air will make you afraid of quiet rooms.
