An audio interface allows you to connect a microphone, instrument or audio source into a computer for recording or to use with voice applications on your computer like Skype and Zoom calls. A typical USB interface allows for stereo (2 channel, Left / Right) audio to be recorded to the computers audio software (DAW). While multi-track enabled interfaces, that user ASIO type drivers and more expensive hardware can record multiple channels to your DAW at the same time. Low latency options from Focusrite allow for using software effects and plugins on your input tracks, while simultaneously outputting the effected signal without delay.
Audio interfaces are devices that connect to a computer (PC or MAC) to provide additional audio inputs and outputs, via a single USB cable. Think of an audio interface is a external sound card for your computer, enabling you to bypass the cheap inbuilt sound cards when recording audio on your computer. An audio interface also performs the critical analog to digital (A/D) conversion.
