Audio/Video Interfaces are devices that connect various audio and video equipment, allowing them to communicate and work together. They can be found in many settings, from home theaters to professional studios. These interfaces help convert signals from microphones, cameras, and instruments into formats that computers and other devices can understand, ensuring high-quality sound and visuals. In addition to connecting equipment, Audio/Video Interfaces often come with features like built-in effects and mixing capabilities. Popular brands like Focusrite and PreSonus offer user-friendly options for both beginners and professionals, making it easier to create and edit content for platforms like YouTube or Twitch.
