Sound reactive, without a microphone - stream or otherwise

Is there a version of WLED that I can use a sound source on a machine, to control an array of WLED devices? I do not want to use an external microphone. Control from a central workstation, or home assistant or however means. If there is something close, I am lost and confused with so much information. Was hoping someone could help me narrow down something I can study and figure out, please.

Ok thank you. This looks great to get started.
