So I'm not sure if I'm too late and you've already figured this out. But it's pretty simple to embed WAV file on IDMf. All you need to is download a Raspberry Pi, install Arch on it, then download some malware from the Google play store. Then you need to break into to Google's HQ.. or just pay Fiddy fiddy bucks to drive over and do it for you).
So once you (or Fiddy) is inside the Google, all you (or Fiddy) need to do is find a network port, jack the Rb-Pi in and then spin it up.
Oh and before I forget! Make sure you (or Fiddy) configure the WiFi access point before you (or Fiddy) leave home because you (or Fiddy) are going to need it.
So once you (or Fiddy) have done this. You (or Fiddy) will need to find a way to access the cafeteria. Once inside, you (or Fiddy) need to go to the baked snacks section and obtain a bear claw. Once you (or Fiddy) have the bear claw in your (or Fiddy's) possession, you (or Fiddy) will need to take it to a quiet place.
When you (or Fiddy) get there, you (or Fiddy) will need to connect to the WiFi access point that I told you (or Fiddy) to setup earlier.
Now. Disassemble the bear claw.
Inside the bear claw you (or Fiddy) will find a micro U(orFiddy)SB stick. The WAV file is contained on the U(OrFiddy)SB stick. Insert the stick into the port on your (or Fiddy's) smartphone to access the WAV.
Now, open the malware app that you (or Fiddy) downloaded from the Google play store and bring up the keyboard and type in the following code as it appears here:
It is very important that you (or Fiddy) enter each character as if you (or Fiddy) don't do this, it will trigger the alarm and all copies of the WAV file on the planet will self-delete.
Once you (or Fiddy) have entered the code, the malware will upload itself (including the WAV file) to the Rb-Pi, which will then transfer it to the Google Play store's central server.
Depending on the size of the WAV file this could take anywhere between two to four hours. What I suggest is that you (or Fiddy) just head to the executive bathrooms and go into a stall and act like you (or Fiddy) are taking a massive dump. I suggest on the day you (or Fiddy) should wear some nice shoes as this will add to the illusion that an important transfer is taking place and nobody who comes into the bathroom will interrupt you (or Fiddy)... because everyone at Google understands the importance of reliable upload/download capacity so they're really supportive like that.
Anyhoo... Finally, once the malware is uploaded to Google Play's central server... Well it would be too technical to explainthe whole process. But basically, you know the end of the last Matrix movie where Keanu Reeves gets super, ratshit fucking blind and hooks up with that giant baby robot thing and then goes on a spirit quest to confront the one to his zero and finally accept that, in defining his existence using a binary scale when the world is non-binary, he's essentially become a one dimensional, shit poster who only ever posts shitty one word posts like "Nah", "Yeah", and "What?" so basically his existence is futile and shit like that?
Yeah. Well, it's basically that. Except at the very end of the film, instead of making the sky all trippy and shit, the little Indian girl will upload your (or Fiddy's) file to the Matrix and then you (or Fiddy) will be able to embed it in your (or Fiddy's) post.
And instead of being all like, "Ooh chain smoking black lady I miss that white dude who I hung out with at the station for like five minutes"... yeah well instead of that she'll post a list in the LB outlining everything that was shit about your track but how it's still got more depth than Keanu Reeves in that movie.
So yeah. Like I said. Really simple.
