However, since every (decent) CD-player has a low-pass filter on it's output, you most definately won't get these. (The output of a CD-player is supposed to be filtered with a low-pass filter muting everything above 22.5 Khz. Due to the fact that there's no such thing as an ideal low-pass filter, there will be a certrain fraction of higher frequencies present in the output signal, but 44k1 is a bit high) -- Martijn van Buul - Pino@dohd.cx - http://www.stack.nl/~martijnb/ Visit OuterSpace: mud.stack.nl 3333 finger email@example.com for my public key block - This message was sent through the cbm-hackers mailing list.
