What is a Stereo Mic?
A stereo microphone is a type of microphone that captures sound in two channels, left and right, to create a stereo image. This allows for a more immersive and realistic audio experience, with the ability to pinpoint the location of sounds in space. Stereo microphones are commonly used in music recording, film, and live sound applications where a wide and detailed soundstage is desired.
How Do Stereo Mics Work?
Stereo microphones work by using two or more capsules, which are the components that convert sound waves into electrical signals. These capsules are usually arranged in a specific pattern, such as the XY or ORTF configuration, to capture the left and right channels. The signals from each capsule are then combined and processed to create a stereo image.
Types of Stereo Mic Configurations
There are several types of stereo mic configurations, each with its own unique characteristics and applications. Some of the most common configurations include:
- XY: This configuration uses two capsules placed in a crossed pattern, with the diaphragms facing each other. This configuration is often used for live sound and public speaking applications.
- ORTF: This configuration uses two capsules placed 17 cm apart, with the diaphragms facing outward at a 110-degree angle. This configuration is often used for music recording and film applications.
- MS: This configuration uses a mid-side microphone, which captures the center channel and the difference between the left and right channels. This configuration is often used for film and television applications.
