Windows Audio Capture (WAC) is an Unreal Engine 4 plugin that captures live audio from the windows default audio device and analyse it to frequency values.
Practically you can create any audio visualisation through Unreal Engine’s BP system by adding custom nodes that react live with your windows audio.
Hey man, I just found this plugin seems like it might be what I needed. Any plans to release a beta for UE5 ? I tried using the 4.25 version on UE5 and it didn’t work.
