A USB turntable, unlike the conventional type, is designed to work with computers; for this reason, most USB models include programs for recording or transferring vinyl to data files. Software packages offered include Audacity, a free, open-source recording and editing program, Cakewalk's pyro Audio Creator LE, the OEM version of the pyro Audio Creator, and MixMeister's EZ Vinyl/Audio Converter. Audacity is used below as an example because it works equally well on Windows and Mac computers and is bundled or recommended for use with several turntable makes and models.
