Good questions Cowboy. I have called the software support line a few times with this and they are moderatley helpful. First of all it should be said that the software support people are not the programming people and so they don't have all the programming information. But what I did find is, yes, there is some additional proprietary information stored in the systems PCM Wav file. Some of this info is the text data that I am looking to "cram" onto the mp3 (I believe rif format) and some of it is other audio playback information (end tones for automation, playback volumes, kill date). The serial number is used to create a seperate air log and so this shouldn't be a concern for the re-encoding that I need to do.
I have uploaded file SP5000 to yousendit.com and sent you the login info via email.
Clearly I am also prepared to hire a temp to come in for a week of data entry.
HA!
