The Plugable Cardioid Condenser USB Microphone digitally captures vocal and acoustic sources clearly and crisply. As a side-addressable cardioid condenser style microphone, this USB mic reduces background noise for a high quality, hassle free audio recording experience. The cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of the intended sound source. Featuring studio-quality sound, this microphone serves as the perfect recording solution for any at home podcaster or recording artist. Offering a simple plug-and-play experience, no drivers are required to start recording. Through the simplicity of USB, this mic is compatible with almost any audio recording software, so you can use this microphone with your favorite recording software.How It Works: Microphones come in all sorts of shapes, sizes, and types. With so many different varieties and functions, shopping for a good quality mic that has all the right specs can be a little daunting. The one thing they all have in common is their basic functionality as transducers to convert air pressure variations (sound waves) into an electrical current (audio signal). Another essential element all microphones share is their diaphragm, which is usually a thin piece of plastic or metal material inside the mic that vibrates when sound waves reach it. An ordinary, dynamic, microphone contains a diaphragm attached to a coil wrapped around a permanent magnet. The permanent magnet moves along with it and provides a magnetic field that allows for electric current to flow through it as it moves. The Plugable USB Microphone is a condenser type microphone, which means that its diaphragm moves the metal plates of a capacitor to generate electrical current. As a cardioid mic, our microphone is unidirectional and picks up sound in a heart-shaped pattern. This configuration allows for it to reject sounds originating from other directions and results in a clear, clean sound quality that works perfectly for voice and acoustic music recording.
