Okay. First of all, audio conversion is a relatively simple topic. There are many finer points to it, but, for most consumer uses it's pretty straight forward stuff. So, it seems as if you are leaving hints of details but not getting into the nitty gritty.
I'm an audio engineer and long-time geek (20+ years at both), I'll surely be able to help you. I just need to know WTF you are talking about. Audio conversion is simple, especially if high-end precision isn't a concern (and it doesn't seem like it is).
So, what can you tell us about this audio that you want to convert? What is the native format? Are you trying to unlock or unprotect something? What is your input?
Lay it out one step at a time. (Honestly, your posts were a bit confusing...even for an expert...and I want to help)
