Changing Speed and Pitch of an Audio File Independently

[zvon]

Pitch-shifting in the early digital audio editors worked like an analog tape. Slowing down the playback rate lowered the pitch and speeding it up raised the pitch.

For many years now, a good number of editors can do these 2 processes independently. I am showing a few examples in this video using Lexis Audio Editor (Android, iOS, Windows) and Twisted Wave (iOS, Mac, online)

In those examples, I was looking for fun variations rather than fidelity or realism.
