Especifications of the native formats to recover lost files

Programming and Development General Audio Programming
1

Hello,

I’m new in this forum but i didn’t found any clue where to find what i’m looking for. I was asked to recover some important files from a radio (some records that where made) in a disk that accidentaly has been erased. I was aiming to use test-disk and photorec. The problem is that this last one has not the files used from adacity to save the recordings. Say the .aup, .awi, .httb, .lof, .lsp. So i must teach photorec how are this files (how the starts and are identified and how the normali end) a long with the extension i already now.

Any one can poin’t me somewhere where are the specifications of how this files are created and saved in the disk? As result probably if i succes and the phorec developers accept my modifications this program will be able to recover deleted files from audacity. Whatever i will be posting somewhere how to do it if it works. So any help will be great!

thanks and hope someone could point me where i must go next.

Audacity Projects have a complex structure. Recovering a deleted project may not be possible.
Here’s a description of what makes up an Audacity Project: http://manual.audacityteam.org/man/Audacity_Projects

There is also a page about recovering projects that have been created by Audacity 1.2.x http://wiki.audacityteam.org/index.php?title=Crash_Recovery

Note that Audacity 1.3.x does not number the .au files in sequence and if the recording was edited in Audacity then the .au files will not be in date/time order. To recover a deleted Audacity Project you will need to recover the .AUP file, ALL of the data, AND the correct folder structure.
