Need to record audio internally, not through the microphone

If you are trying to grab the audio from a tradtional video file (mov, mp4, wmv, etc)...   Then open that file with a basic video editor and all of them (pretty much) will let you export/publish the sound only into a music file. (Vegas Home Studio, AVS4You video editor or video convertor, etc)

If you are trying to grab the audio from a published e-learning project.... They (Articulate or otherwise) typically capture sound in stand alone sound files (think MP3) and then pull them in when needed during playback.  Just locate that file(s) in the published package and drag them into where you need them.

If you are trying grab sound this is truly "buried" in a Flash file  (ie not linked to, but recorded in a SWF, FLV)... you would use a tool like AVS4You audio editor, MP3Grabber, Audacity, to catpure it out of the Flash and into a conventional sound file format.

In any case, you shouldn't have to record the sound from a microphone/speakers as it already exists as a file somewhere.  If it's already digitized on your computer somehow, don't even consider converting it multiple times (D>A>spl then back from spl >A >D). Instead just keep it in the digital world as outlined above.  Make sense?

Hope that helps,
