I'm trying to eliminate an echo mistakenly recorded with 2 mics on in OBS. It's long and I really don't want to record it again. In fact I can't because things are too different from when I did the first recording. I managed to disconnect the audio from the video but that's as far as I got. Everything I've read on the web tells me to find an "Edit" button above the timeline or right click and find the Audio button. Can't find anything above the timeline except except Tools, Fix/Enhance, Keyframe and the properties button. None of those give me what I need.

Audio button and even Tools don't give me an AI option except for AI Speech to Text. I don't have enough knowledge to mess around with the audio mix and Denoise doesn't do anything for me. I've contacted support but that was on the 23rd. It's now the 28th and I haven't heard a peep from them except to send me a link for my support ticket. I really need some help. I managed to stretch my deadline but not for much longer.
