Abstract: Automatically matching local broadcast station copies of commercial content to previously identified content that is centrally attributed to a unique identification code is provided. A local broadcast station receives digital audio and processes the contents into a data profile of 1,024 bits. The data profile is compared with a master database of other content data profiles until an identical match is found. A corresponding commercial identifier is employed to identify the subject content digital audio file to the station's Broadcast Production System. The determined commercial identifier is injected as a digital artifact into the carrier of the content digital audio file, and associatively stored with the content digital audio file. During the performance process, the appropriate commercial content digital audio file is sequenced by matching the commercial identifier associated with the digital audio file.
