Omnidirectional Pickup Pattern
This technique captures sound equally from all around the microphone. It's best used in environments where sound is coming from multiple directions and a natural ambiance is desired.
Shotgun/Polar Pattern
Utilizes a highly directional microphone which captures sound from the front while rejecting sounds from the sides and rear. It's best used in film and video production to record dialogue.
Decca Tree
A spaced array of usually three omnidirectional microphones used to capture a wide stereo image with depth. It's best used for orchestral recordings where a natural balance and blend of the ensemble is needed.
Cardioid Pickup Pattern
This technique uses a unidirectional mic with a heart-shaped pickup pattern. It's best used for isolating sound from a single source while minimizing background noise.
XY Stereo
This technique involves two cardioid mics placed at a 90-degree angle to create a stereo image. It's best used for capturing a wide stereo field with good mono compatibility.
ORTF Stereo
Employs two cardioid microphones placed 17 cm apart at a 110-degree angle, emulating human ear spacing to capture a natural stereo sound. It's best used for capturing audience perspective in live recordings.
Boundary/PZM (Pressure Zone Microphone)
This technique involves placing a microphone on a flat surface which captures sound with less phase interference and provides a clear, natural sound. It's best used for theater or conferences.
Figure-8/Bidirectional
This technique captures sound from the front and rear of the microphone but rejects sounds from the sides. It's best used for recording two sources facing each other or for use in mid-side recording.
AB Stereo
Requires two omnidirectional microphones placed apart from each other to capture a natural stereo sound. It's best used for orchestral or choral recordings where room ambiance is desired.
Bass Roll-Off
This is not a placement technique but a setting on many microphones and preamps that reduces low-frequency noise. It's best used to minimize rumble or handling noise from recordings.
MS (Mid-Side) Stereo
This technique combines a cardioid (mid) and a figure-8 (side) microphone to capture a stereo image that can be adjusted in post-production. It's best used for flexibility in stereo width.
Blumlein Pair
Involves two figure-8 microphones arranged at a 90-degree angle to each other, capturing a realistic stereo image with excellent spatial qualities. It's best used for acoustic ensembles in a good-sounding room.
Binaural Recording
This technique uses two microphones placed in ear-like cavities or a dummy head to simulate human hearing. It's best used for creating immersive 3D audio experiences with headphones.
Ambient Miking
Placing microphones farther from the source to capture the sound of the room or environment. It's best used to add a sense of space and realism to a recording.
Close Miking
Placing the microphone near the sound source to capture a direct sound with minimal room acoustics. It's best used for recording in non-ideal rooms or to isolate individual instruments.
