Audio ripping from videos

[Gooned88]

Hi all! So this is my 1st post here. First off I'm super new to any kind of audio editing or anything of the sort. I've lurked here for quite awhile getting great ideas for estim related videos to use on my 2B. I've found a few videos that I'd like to take the audio from and make a simple stim mp3 file out of, but I really can't think of an easy way to isolate one sound from another that's in a video. Like for example this video (https://spankbang.com/662eq/video/3x3+asdfasd) I want to take any speech out of the audio and just leave the waveform-like audio in the background and hook it up to my 2B. Is there any easy way to do that? Or would it be easier to just find a way to make my own audio that's similar to the audio in the background of that video? I downloaded Audacity and tried messing around w/ random things in there, but I have 0 knowledge of how to use that program efficiently so I might as well be wandering around in the dark. Figured I'd ask the knowledgeable folks here if there's any easy way to go about that or if someone is awesome enough to do it for me, you'd be a god. lol. Thanks in advance for anyone that can help!

Download the video and open it with audacity, it can import many audio formats even if they are contained in some video container like mp4. I also have used avidemux in the past. It can export audio tracks only from a video and transcode it into various formats. Not sure, which formats it can read, but I never had something I could not play.

I have no problems separating the audio from the video. My main concern is editing the audio to ONLY have the binaural wave sounds from the background in the audio and removing any speech from the audio. If I just separated the audio from the video and ran that thru my 2B as is, having the random bursts of speech in the file wouldn't feel as good as having just the smoother binaural wave audio going.

I have a sneaking suspicion that what I'm wanting exactly is gonna be harder to do than I want it to be.

Audacity has a "remove vocals" filter that may or may not work depending how the audio is put together.

Caveats; I have no experience with stim and I have very little experience with audio, but..:

Separating sounds from a single track isn't easy. I would try not to fry my junk with anything that has been algorithmically extracted.

If you had a cleaner sample of the binaural you're after, it might be easier to copy-paste from a single clean part to whatever length you want. That vid you linked seems to have voiceover all throughout (just based on jumping around in it), so I don't know if there would be clean enough bits.

If you go copy-pasting, I'd assume you want all the cuts to be smoooooth at the graph. A jagged edge will cause audible pops (basically firing at all frequencies), which could lead into audible screams in your viewing area.

If you want binaurals specifically, you can generate them pretty easily in Audacity, just generate a different frequency on each stereo track. If you generate 400 Hz on one side and 401 Hz on the other, you get an audible 1 Hz wave; the "extra" wave is at the frequency of the difference (401-400). I have NO idea or advice what that does for stimming though; the stim files I've heard are not exactly binaurals (only really heard them when I've looked at a stim tease here, so, not exactly an expert on the matter)

Just a suggestion, don't know if it works that way...

How about you play the video, and at the same time, you set your e-stim box to manual and record the output by just playing with its control knobs? You have instant feedback if it feels good, and you can play/share the recording for future sessions.

Like everyone else is saying extracting clean audio is really hard and probably beyond consumer capability. You could try contacting the person who made the video, however, and see if they still have all the source files and are willing to share.
