Watermark removal software doesn't have to play the sound in real-time, though. mark cox wrote: "Sounds like that software would be kind of slow to play a song in real time but I don't know." Why ever would you even NEED to remove the watermark while playing the track? The point of watermark removal is to produce a file that doesn't have the watermark, so that it can be re-distributed without identifying the source. If it can be done in 1/10 real time, that is fine. mark cox also wrote: "the information I read about watermarking stated that they put a 10 bit code into every single second of song. Now if that song is 3:30 long you would be talking about slicing that file up into 210 different parts." I'm not sure what you mean by "slicing up". You'd be removing the inaudible sounds that carry that 10-bit code, most likely by digital signal processing. You wouldn't be "slicing up" anything. You would be removing certain sounds that, by design, are inaudible to the human ear anyway.
