[Tutorial] How to change your voice live on Skype using GarageBand (Mac)

Another self-reference post. Sorry to any of my followers because I'm sure you followed me for my rants and rambles instead of these technical tutorials. :p

Soundflower
Download Soundflower.


GarageBand
Click the GarageBand menu, then click Preferences.
Change the audio output to Soundflower (2ch). Leave your mic as the audio input.

Create a new track and select "Real Instrument".
Then turn on the monitor.

My GarageBand is quite old so it might look different to yours, but they should all have the option to turn on/off the monitor.

Click "Details", which is right below the monitor option. Change your voice however you want.


Skype
Go to Preferences and set the audio input to Soundflower (2ch).

My version of Skype is also quite old, btw.

Then you should be done! :D You can try calling Skype Test Call to make sure it works.
