Because It Was Thereis a companion website for Mark Mangini's book on the art and craft of sound design for film.

The book references hundreds of sound effects that have shaped cinema history. This site lets you hear them instantly — simply enter the 3-digit code printed next to each reference, or scan the QR code on the page.

Each sound effect is presented with a full waveform visualization, playback controls, and context about where and how it was used.
