Welcome to the forum! We’re glad to have you aboard A reverse delay would be pretty cool but I’m not sure you could build one with the nodes we have at the moment. There is a delay node, but I can’t see any easy way to reverse the audio. Maybe if you set the delay for say one second then after a second set it back to zero then swept it forward back to one second in 0.5 seconds. Might be worth a try.
Here’s something that is sort of a reverse echo. It periodically reverses the playback. I’m not sure that it’s exactly what you had in mind, but it sounds pretty cool anyway. Reverse Echo V1.0.audulus (431.6 KB)
