Basically it gets audio into and out of your computer, turning analogue audio signals into digital information (in) and digital information into analogue audio (out). One of the key components to any Audio Interface are the converters that handle this process, known as AD/DA convertors. This quality of these convertors varies from product to product and often has an influence on price. Some users need analogue to digital conversion to create a digital source for something other than a computer (such as a digital recorder or mixing desk), these people would use an AD convertor rather than an Audio Interface.
Units also vary according to what kinds and number of connections they have for getting audio in and out of the unit. Most Audio Interfaces will have a number of microphone inputs and line inputs. Microphone inputs use balanced 3-Pin XLR sockets and in most cases, these inputs will also provide 48V phantom power for use with studio condenser microphones for vocals and instruments. Line input sockets are either the ¼” balanced variety, or unbalanced RCA sockets found on DJ Equipment. These sockets will accept signals from synthesizers, drum machines, DJ mixers. It is important to note that these line inputs are always mono so if you need to record a stereo signal, you’ll need to use two inputs on the soundcard.
