[Audacity 2.4.2 on Windows 10] How to dynamically adjust sound speed?

I am currently running Audacity 2.4.2 on Windows 10, but I'm pretty sure this question can also apply to the same version on macOS and Linux. My question is: Is there a way to dynamically adjust a sound's speed? Specifically, what I want to do is take a section of a sound and slow it down gradually, instead of all at once.

You can use a Time Track - please see: https://manual.audacityteam.org/man/time_tracks.html

Turns out that was so simple I feel like a n00b for asking that question. Still -- it's something I didn't know before, so I... guess it counts...?

Anyway, here's a nice little YouTube vid I made that features my slowed-down audio track. https://www.youtube.com/watch?v=ff0HQlNR1sM

It's only easy when you know how ;)

It's not obvious from looking at the GUI that
a) you can add a Time Track
b) figure out what it does

Have fun,

Peter.

An alternative approach which may or may not be intuitive is to use the Sliding Stretch effect.

I hope this helps. :D
