A computer microphone is a device that allows you to input sound into a computer. Microphones work on the principle of converting sound waves into electrical signals.

The most popular types of computer microphones include:

  • Condenser Microphones: More sensitive and used for recording vocals and acoustic instruments
  • Dynamic Microphones: Sturdier and less sensitive, commonly used for live performances and recording electric instruments
  • USB Microphones: Condenser microphones with a built-in USB interface for direct connection to a computer
  • Wireless Microphones: Use radio frequency to transmit the signal from the microphone to a receiver, which is connected to the computer

When a sound wave enters the microphone, it causes a diaphragm to vibrate, which changes the distance between a magnet and a coil. This creates an electrical signal that can be recorded or transmitted to the computer.

Most computers have a built-in microphone, but for better quality, external microphones are recommended.
