Answer by user2117580 for Speech processing pre-emphasis: how does it work?
This is just a derivative in discrete time domain. A high value means the signal changed rapidly, what means between the samples n and n - 1 there are high frequency components.

Signals of low frequency sampled at a highly enough rate, tend to yield adjacent samples of similar numerical value. The reason is that low frequency essentially means slow variation in time and so the...

In speech processing, the original signal usually has too much lower frequency energy, and processing the signal to emphasize higher frequency energy is necessary. To perform pre-emphasis, we choose...
