Niagara Microphone Input Soundsubmix Not work

I’m making an effect which responds to sound(from microphone input)

I added Soundsubmix but for some reason it didn’t work.

i’m new to Audio Programming so i almost
know nothing about it.

i followed

this video, but it’s different version from what i use so submix is different and i don’t know how i can handle that.

In youtube, output volume of audioInputAnalysis is 1.0 (at 2:30 seconds at video), but in my version i can not make the volume over then 0. why??


does it make sense that volume can only be negative value??

sorry for my english and i need you guys help.

have a nice day!
