extract sound from a fla

Ok I know this is an old post, but if your using cs5 and above all you need to do is copy your .fla, change the extension to .zip, open the .zip go to file/library and than grab the audio file.

1. Right-click on the asset in the Library -> "Copy"
2. Create a new file
3. Right-click on the Library of the new file -> "Paste"
4. Click and drag the file onto the stage
5. Adjust (expand) the timeline so that it covers the whole audio
6. "File" -> "Export Movie"
7. "WAV Audio"

I tried to export was WAV, but couldn't find the option.

Don't know if it will help, because what I did is a bit long winded, but here goes:

1. I imported a .WAV file into the library
2. I've set it on the main timeline(as if you were to copy your wav file to new document and place it on the timeline) and set it to Stream
3. I've made the stage size 1 X 1 pixels ( not sure if necessary though :))
4. I've chosen File > Export Movie > QuickTime
5. In the QuickTime settings I've ticked off Video and Prepare for Internet Streaming
6. I've noticed the quicktime movie was the exact size as the wav file, not sure if it's a coincidence. I imported it into Soundbooth and Saved it as a wav with the settings it had ( 44100Hz, 16bit, Mono in my case)
