Hi,
A few years ago I'd created some PDFs containing MP3 sounds, using the Acrobat 8 multimedia tool. At this time I thought it was reliable (stupid, isn't it?), so I'd trashed all MP3s original files…
Now, using Reader/Acrobat 9, I can't play these sounds because of the yellow bar of death who display a security warning.
I'd like to extract MP3 files (to re-create new PDFs using the Acrobat 9 Rich-media tool).
Is it possible ?
1) Open the PDF and select "trust once" in the yellow DMB.
2) Click the annot so the audio begins to play.
3) In the Windows Start Menu, choose Run, and enter %temp%
4) In the folder that opens, sort by descending date. The most recent file will be your MP3, with a semi-random filename (it may be the name of the PDF, but it depends how you made it).
5) Copy the MP3 into another folder, then close the PDF.
The above works because you've used legacy MM, and so Acrobat/Reader has to export a temporary copy of the MP3 so your audio software (Quicktime, Media Player, etc) can access it. It's only there while the audio annot is playing, so grabbing anything that's really short is a challenge! With native Acrobat 9 Rich Media this doesn't happen as playback is entirely within the process - so next time don't throw away your originals ;p
Obviously if you have a bunch of files to extract from, you can keep the folder view open and they'll pop up on the list as you go.
