A voice changer app for saving security instead of non liberal governments at online calling

Question

I need to save me or other security some times for two usages (because of some political restrictions and problems via non liberal governments from religious parties or...):

1. when I record the podcast

2. calling for some media like TV or online radios (live contacts).

So I googled and find this link:

Can I change my voice into another person's voice through any software as is shown in movies?

which described some software like vocal free or DJ Voxchanger which was for IOS or Windows, so I have Linux Mint and Android 6 mobile phone, there was one app (Girl Prank Voice Changer).

So could you say, what is the proper app or software for these usages, which could not be recreating the main sound source?

Thanks.

Answer 1

OK so I would tend to approach this with a number of different plugins and functions, typically using pitch and formant change, bit-crushing, modulation. I would tend not to want to approach this with a single plugin as it would be easier for the powers-that-be to be able to reverse-engineer the sound. If you are creating a unique approach to this it will be harder to undo the effect.
