A few ways of “watermarking” mp3 files
Monday, February 12th, 2007Recently there has been talk by some music labels that they will be releasing non-DRMed mp3 files, followed by updates that they are going to “watermark” these files.
I choose to write “watermark” quoted, as this is really more tagging than watermarking, because I doubt they will be applying on-the-fly digital audio processing to watermark, followed by encoding each mp3 specifically for each customer. Let’s assume they’re going to just modify stocks of ready-encoded mp3s.
