I. What is a Figure-8 Pattern?
A Figure-8 Pattern, also known as a bidirectional pattern, is a type of microphone polar pattern that picks up sound equally from the front and back of the microphone while rejecting sound from the sides. This pattern resembles the number 8 when plotted on a polar graph, hence the name Figure-8.
Figure-8 Pattern microphones are commonly used in recording studios for various applications, including capturing vocals, instruments, and ambient sounds. They are versatile microphones that can provide a unique sound character due to their bidirectional nature.
II. How does a Figure-8 Pattern microphone work?
A Figure-8 Pattern microphone uses two diaphragms that are positioned back-to-back within the microphone capsule. When sound waves hit the front of the microphone, one diaphragm moves to capture the sound, while the other diaphragm moves in the opposite direction to cancel out sound from the back of the microphone. This design allows the microphone to pick up sound sources in front and behind it while rejecting sound from the sides.
The Figure-8 Pattern microphone is sensitive to sound coming from the front and back, making it ideal for recording situations where you want to capture sound from two different sources simultaneously. This can be useful for recording duets, interviews, or capturing room ambience.
III. What are the advantages of using a Figure-8 Pattern microphone?
There are several advantages to using a Figure-8 Pattern microphone in recording situations. One of the main advantages is its ability to capture sound from two different sources simultaneously. This can be useful for recording duets, interviews, or capturing room ambience in a natural and balanced way.
Another advantage of Figure-8 Pattern microphones is their ability to reject sound from the sides, which can help reduce unwanted noise and bleed from other instruments or sources in a recording environment. This can result in cleaner recordings with better isolation of the desired sound sources.
Additionally, Figure-8 Pattern microphones can provide a unique sound character due to their bidirectional nature. This can add depth and dimension to recordings, making them sound more natural and immersive.
IV. When should you use a Figure-8 Pattern microphone?
Figure-8 Pattern microphones are versatile tools that can be used in a variety of recording situations. They are particularly useful when you want to capture sound from two different sources simultaneously, such as recording duets, interviews, or capturing room ambience.
Figure-8 Pattern microphones are also great for recording instruments with complex tonal characteristics, such as string instruments or brass instruments. The bidirectional nature of the microphone can help capture the full range of frequencies and harmonics produced by these instruments.
Additionally, Figure-8 Pattern microphones can be used for stereo recording techniques, such as Mid-Side (M-S) recording or Blumlein stereo. These techniques can create a more immersive and natural sound image in recordings, making them sound more spacious and realistic.
V. How to position a Figure-8 Pattern microphone for optimal results?
When using a Figure-8 Pattern microphone, it is important to consider the positioning of the microphone for optimal results. Here are some tips for positioning a Figure-8 Pattern microphone:
1. Position the microphone so that the front and back of the microphone are facing the desired sound sources. This will ensure that the microphone picks up sound from both sources while rejecting sound from the sides.
2. Experiment with the distance and angle of the microphone to find the best balance between the two sound sources. Moving the microphone closer or further away from the sources can affect the sound quality and balance in the recording.
3. Use a shock mount or isolation mount to reduce handling noise and vibrations that can affect the recording quality. Figure-8 Pattern microphones are sensitive to vibrations, so it is important to minimize any external disturbances during recording.
4. Consider using a pop filter or windscreen to reduce plosives and wind noise when recording vocals or instruments close to the microphone. This can help improve the clarity and quality of the recording.
By following these tips and experimenting with different positioning techniques, you can achieve optimal results when using a Figure-8 Pattern microphone in recording situations.
