Left is scalogram of exponential chirp, right is of a bunch of these within time shifts (Shepard Tone):
Is there audio terminology for describing this, besides "rising frequency"? Rising pitch? Rising timbre? Would the two cases be described with different phrases (ignore cross-fading etc for the right case, just focusing on the rising aspect)?
The idea's to describe any positive slope in time-frequency - I have a method that does it, and would like an audio-friendly wording to label it. It should also go the other way, for "falling frequency".
