[Tutorial] UE4 Niagara Audio Capture (Mic Input) Setup

[Applause] this is vj fader uh in this tutorial i'm gonna show you how to set up live audio input basically using your microphone in your unreal niagara visualizer project let's get started first of all i'm gonna clone my level that i created from the last video so if you want to check out the last

tutorial check the link in the description so i'm going to duplicate this level and call this niagara spectrum dash audio capture and open that up i'm gonna delete uh this sound cue that i've created that's uh playing this music in a loop and then create my blueprint in here let's make a new blurprint actor

and call this audio analysis and double click this is going to be super simple all we need to do in here is really add a audio capture component so i go audio capture as my component and then you can leave the name as default it's called audio capture and let's compile and save this

all we need to do is drag this into our scene uh i'm going to move it into my audio folder so after you have placed this audio analysis blueprint actor into your level uh you need to assign a sub mix to this so you could just assign one of these default sub mixes however

what happens is when you have audio capturing into unreal and then it will automatically output that out to your speakers and that creates a feedback so you can kind of skip this step without creating a custom sub mix by just muting your speaker on your computer so that way you don't create a feedback

but we can go ahead and make this sub mix so in my sub mix folder i'm going to go right click create a sound and mix sound sub mix and it's called this audio input analysis and then i'm going to create a second sub mix where i'm going to mute the audios called um mute
