Thanks for clarifying this issue. Theorically, A 44100 sampled audio CD can reproduce a triangle signalat 22050 Hz. The triangle signal is the worst possible but DAC convertit to a sine signal. Anyway, the first harmonics of a 22050 Hz distoredsignal are ultrasonic "sounds" such that we can not hear the distortion,Even if the headphone might reproduce a 28Khz sine or over. -------------------------------------------------------------------------This SF.net email is sponsored by: MicrosoftDefy all challenges.
