The problem is you can't save the file to ChromeBook. What i would do is to look for a lite audio recording software like "app" that would run off a flash/zip drive or SD card. Install the lite app on the zip from a regular PC and see if you can get ChromeBook to run it. You can save the recording to the zip drive (main problem) I am waiting for them to come out with a ChromeBook with SD drives on the bottom of chrome book just for this. Thus one would mount a SD drive to run Apps on ChromeBook and have off line storage on the drive too.
