Audio USB adapters are essentially external computer expansion cards that plug into the computer via USB. The audio card facilitates the input and output of sound signals to and from a computer according to control of computer programs. All the sound is created in software programs within the Computer. The audio USB adapter box only provides for connectivity coming from the computer by means of the usb bus to an external device like a microphone in or line in/out connector. These external USB boxes are more accurately termed audio USB adapter interfaces rather than sound cards.
The USB specification defines a standard interface, the USB audio device class, allowing a single driver to work with the various USB sound devices on the market. Audio USB adapters meeting the USB 2.0 specification have a sufficient amount of data transfer capacity to support a high quality audio operation.
The benefit to users of this type of solution is they do not have to install an internal sound card to get sound from the computer. All they need is a computer with a USB port. This allows the user to be able to unplug the audio adapter at any time and remove the sound capability from their computer. Also they gain easy transportability because they can unplug the adapter from one computer and plug it into another.
