The Science of Microphone Polar Patterns
Learn about microphone polar patterns and their applications, including cardioid and figure-eight. Maximize sound capture and minimize noise. Capture natural room sound and manipulate sound with different patterns.
00:00:00 Learn how microphone polar patterns work with illustrations and audio demonstrations. Understand cardioid, figure-eight, and omni patterns and their applications.
🎙️ Microphone polar patterns determine how sound is picked up and rejected.
🤔 Cardioid, figure-eight, and omni are common microphone polar patterns.
🔊 Cardioid pattern picks up sound best from the front and rejects sound from the rear.
00:01:30 Learn how microphone polar patterns work, including cardioid and figure-eight. Use the directionality of the mic to maximize sound capture and minimize unwanted noise.
🎙️ Cardioid microphones are useful in live performances and rooms with poor acoustics due to their directionality and ability to reject unwanted sounds.
🎵 The proximity effect in directional microphones can boost low frequencies, but it can also result in a muddy mix if not controlled.
🔀 Figure-eight or bi-directional microphones pick up sound from the front and rear, while rejecting sound from the sides.
00:02:59 Learn how microphone polar patterns like cardioid, supercardioid, omni, and figure-8 work and their benefits in recording acoustic guitar and capturing natural room sound.
🎙️ Different microphone polar patterns, such as cardioid and bi-directional, have unique characteristics that affect signal-to-noise ratios and sound isolation.
🎸 Bi-directional microphones are effective for recording acoustic guitar, as they help isolate the guitar sound from background noise and vocals.
🎧 Bi-directional microphones are susceptible to the proximity effect, resulting in a bassy sound when recording up close. They are best used in combination with other microphone types.
00:04:28 Learn how microphone polar patterns work, including omnidirectional microphones that capture sound from all sides and the advantages of using them in different recording environments.
🎙️ Omnidirectional microphones pick up sound evenly from all sides, capturing both the instrument and the room's ambience.
🔊 Omnidirectional microphones are less susceptible to wind noise, plosives, and handling noise compared to directional microphones.
🎧 Omnidirectional microphones do not exhibit the proximity effect, making them versatile for studio and location recording.
00:05:58 Learn how microphone polar patterns work and their applications. Understand directional microphones and their frequency response.
🎙️ Different microphone polar patterns, such as cardioid and supercardioid, offer varying degrees of directionality.
🔄 Microphone polar patterns can be used to reject noise coming from angles other than directly behind or from the side.
📊 The polar pattern graph on a microphone shows its sensitivity and response to different frequencies.
00:07:27 Discover how microphone polar patterns work, including omnidirectional, bi-directional, and cardioid patterns, and how they can be used to manipulate sound.
🎤 Microphone polar patterns affect the directionality of sound capture.
🔍 Early microphones were omnidirectional or bi-directional.
🔄 Combining pressure and pressure gradient microphones creates the cardioid polar pattern.
00:08:57 Learn how different microphone polar patterns work, including cardioid, supercardioid, omni, and figure-8. Discover how they combine to create other patterns.
🎙️ Microphone polar patterns determine the sensitivity and directionality of a microphone.
🔄 Some microphones can switch between different polar patterns, including cardioid, figure-eight, and omnidirectional.
🔊 Combining cardioid signals creates an omnidirectional pattern, while reversing the polarity of one signal results in a bidirectional pattern.
