Very simple javascript project

This is very simple bit of code (three or four lines) as a hobby project. Aim - set the encoder type in itunes via javascript. example: var iTunesApp = [login to view URL]("[login to view URL]"); [login to view URL]('B:\[login to view URL]'); This adds a file to itunes. I need to set the currentEncoder and do not know how. I need the three or four lines of code to show me. from SDK: HRESULT IiTunes::CurrentEncoder ( [in] IITEncoder * iEncoder ) Sets the current encoder (AAC, MP3, AIFF, WAV, etc.). Parameters: iEncoder An IITEncoder object corresponding to the new encoder.
