All of this conversation raises this question in my mind:
I have to assume that if it has not already been done, a piece of software could be written that would scan & analyze a file and determine what kind of processing would be appropriate for the file.
Station operators and programmers would then have a choice: Ask this software to create a database listing all the files scanned (could be music, commercials, station promos, talk show re-runs, whatever, and then a human could scan the database output and make a human decision.
Then files could be processed in-place on the hard drive, or if it is preferred to keep the original files in the automation, tag the file with a code that would cause the appropriate selection of processor to route each file through at time of broadcast.
Is this being done? Has it been rejected as too cumbersome or unreliable?
