Thanks for clarifying this issue.
Theorically, A 44100 sampled audio CD can reproduce a triangle signal at 22050 Hz. The triangle signal is the worst possible but DAC convert it to a sine signal. Anyway, the first harmonics of a 22050 Hz distored signal 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: Microsoft Defy all challenges.
