Just curious, TTYL > I am not sure if it is true for that particular encoding system, but usually they also include a watermark: A serial number unique for every customer encoded in non-audiable frequencies. So you can crack the encoding and produce a free format sound file or even record the music on your tape deck, but they can still tell you who has bought that copy. > ... some chinese proverb; "Show me a rock, I will show you a way to get > over it". > > ... some friend's proverb; "The same human inteligence that creates a > way to lock a door, is also used to unlock it". > Exactly as there are no non-breakable doors, read-protected Micro- controllers and chip cards, only time and costs are different. > I heard that some FM radio "live shows" just use thousands of digitized > musics stored in hard disks, so when a phone caller request a music, it > is a matter of 4 seconds to start to play it.

I have read an article about german radio stations: most of them are playing songs from the hard disk and IIRC it was MP3 with 196 kbps. It was even enough for decoding-cutting-and- re-encoding some times without noticeable quality losses. ... > When you buy a newspaper for $1.00 you are poorly paying the > half of the recycled paper costs.

Completely paid by ads. Just my 2 cents ... St.
