ORTF

ORTF is a stereo microphone placement technique developed by the Office de Radiodiffusion Télévision Française, using two cardioid capsules spaced 17 cm apart and angled at 110 degrees. Accessories designed for ORTF recording help maintain precise capsule positioning for consistent stereo imaging and natural soundstage reproduction. Broadcasters, location sound recordists, and classical music engineers rely on this configuration for its accurate spatial representation and compatibility with mono playback.
