[Any budget reccomendations for a voice changer?]

I CAN solder! thank you very much!, ordered one on amazon just now, I have 3D printed the helmet so hopefully I can install it onto the helmet

[Any budget reccomendations for a voice changer?]

Hello, this is my first post on the forum so sorry if I've missed something.

 

I was looking for voice changers and after going through everything in this section, everything I can find is either super expensive or discontinued, I was wondering if anyone knows a budget solution (i'd like to keep it under $100CAD) for the voice changer? I've seen some android apps recommended but unfortunately for me I only have an iPhone at my disposal RN.

 

Thanks!
