Change audio pitch? (so effects are varied)

How do I change the pitch of a sound effect? I want to put a random value so that it'll help make the audio more varied and interesting.

This question is asked frequently on this forum.

Unfortunately, even in C3 there is still not possible to change pitch.

I found that "Ring modulator" effect can be used to add variations to some sounds. Also you can change playback rate (but this will obviously decrease sound duration).

That's odd there's no way, thanks for your reply.

Changing the playback rate changes the pitch.
