It’s imperative I get it in their original unedited sound file form and in MP3 as .wav is too big and .ogg could crash certain programs like Vegas Pro.
I always hate it when somebody asks for help on a site like StackOverflow, and some smartass pipes up with “Why are you even trying that, why don’t you try ___ instead?”
I don’t want to be that guy. But I am very, very curious about why it is so imperative that you obtain the actual original audio files. Why would similar sounds not suffice?
For context, I am an audio editor / producer / sound designer / Foley artist, and I’ve run into that same problem, of old sound libraries not existing anymore, and have had to find, or create, my own alternatives. So I do know the struggle, but I don’t know your particular situation.
Lol, no kidding!
