To expand the insight, you may see this video about Wavelets which relates them to the Fourier transform.
It explains wavelets as an intermediate point between pure waves (all time, no frequency representation) and the Fourier transform (all frequencies, no time representation), with wavelets having part of both.

Fourier Transform maps between global frequency space sampling and (repeating wave for all time) and local positional/point space sampling (perfect impulse). Wavelets map to an intermediate space,as you say, with smeared points/impulses and damped waves.
- dsego 4y agoIn this aspect, are wavelets similar to how stft is done with a hann window or the like?
