Stereosonic Recording
A technique pioneered in the 1950s using multiple spaced omnidirectional microphones to record true-ambient stereophonic sound.
Jecklin Disk
A technique where two omnidirectional microphones are spaced apart behind an acoustic baffle, creating a sense of spatial separation and depth.
NOS
A Dutch technique using two cardioid microphones spaced 30 cm apart at a 90-degree angle, aiming for a balance between stereo imaging and mono compatibility.
XY
A coincident technique where two cardioid microphones are placed at a 90-degree angle to capture a stereo image with good mono compatibility.
Binaural Recording
A recording technique that uses two microphones placed in the ears of a dummy head, simulating human hearing to create a 3D stereo sound.
Double MS (DMS)
An extension of the MS technique involving a rear-facing cardioid mic to create a surround sound recording.
Holophone
A patented microphone system designed to record holographic, 360-degree audio suitable for surround sound applications.
Stereo XY with Angled Capsules
A variation of the XY technique using angled microphone capsules to capture a wider stereo image.
Blumlein Pair
A coincident stereo technique using two Figure-8 microphones at a 90-degree angle, offering a realistic stereo image with good mono compatibility and sense of room space.
DIN
A near-coincident technique similar to ORTF but with microphones spaced 20 cm apart and at a 90-degree angle; designed for a good balance of stereo separation and mono compatibility.
Ambisonic Recording
A full-sphere surround sound technique that captures the directionality and intensity of sound from a single point in space, often used with a soundfield microphone.
Decca Tree
A spaced microphone array typically involving three omnidirectional microphones arranged in a T-shape to capture orchestral recordings.
Boundary (PZM)
A recording technique using a microphone placed on a flat surface to capture sound waves after they've reflected from that surface, reducing phase cancellation and adding clarity.
ORTF
A near-coincident technique developed by the Office de Radiodiffusion Télévision Française where two cardioid microphones are spaced 17 cm apart at a 110-degree angle for a natural stereo image.
MS (Mid-Side)
A stereo technique where a mid microphone (cardioid or omnidirectional) faces the sound source and a side microphone (Figure-8 pattern) captures left and right stereo information, requiring matrixing to decode.
HOA (Higher Order Ambisonics)
A recording technique that captures the sound field in three dimensions using a spherical microphone array, suitable for virtual reality audio.
Faulkner Array
A stereo technique using two Figure-8 microphones arranged parallel to each other with a small distance apart, often used for rich, ambient recordings.
AB
A spaced pair stereo technique using two omnidirectional microphones placed several feet apart, providing a wide stereo image but with less mono compatibility.
