Thanks guys for the kind words 
Glad you like it.
BTW I had added another BP node after I made the initial post - it just returns the SoundWave object instead of playing it directly.
I looked into setting up the Dialogue nodes as well, but it seems like they don’t load a sound directly anyway, so the node for loading to a SoundWave should be sufficient to use the Dialogue BP nodes already.
I’ll be looking into adding MP3 decoding support to the plugin sometime soon.
Massive thanks go to @keru for his original snippet for loading Ogg files into a SoundWave, and to @Rama for his BP library plugin, which I used as an example to set this one up.
