In Reply to: Is single sample of 44.1kHz sampled data audible? posted by dave789 on March 12, 2012 at 21:22:31:
I'm not exactly clear on what has prompted this question for you. I will say, however, that the half-wave 'pulse' appearing at the center of a sinc filter impulse response implies a full-wave periodic frequency of 22.05kHz, and shouldn't, itself, be audible. I've empirically determined the sinc filter's impulse ringing to extend down to somewhere between 19kHz--20kHz, and not narrowly limited to 22.05kHz. Furthermore, I'm convinced that a typical sinc filter's impulse response ringing indirectly generates unpleasantly audible side effects across a digital audio recording/playback chain, even though the ringing frequency of such filters is near the lower edge of the ultrasonic band.
