Take a .5 millisecond 10kHz centered guassian pulse.Play it out the DAC on your computer. LIsten.
Now, fiter it with a (very long) FIR filter that will cut off between 20kHz and 20.1 kHz. Yes, it will be long, best done as fast convolution, etc, but in modern systems you can design and use such a filter.
Listen for pre-echo and see if you can hear any. :)
