One last point,
For higher frequencies, at 44.1 KHz sampling rate, this may correspond to only a few samples. The shape of a quickly changing signal can’t be faithfully captured by such small number of samples.
This demonstrates, succinctly, a lack of understanding of the topic we are discussing. Perhaps the problem is you only see a few samples. What you should see is a few samples, taken at very precise time intervals. The information is not only the sample value, but the exact relative time of each sample. Both are critical.
