Audacity Recovery tool won't work - need help stitching data

[bengomori]

Hi guys

Recorded a live set using
Mac OSX 10.7.5
Recorded with Audacity 1.3.14-beta (didn't realise it was so out of date but bear with me here)

I think I forgot to hit save or deleted the project file, so all I've got is the .au files. All the data is there. I have used Automator to rename it sequentially so that the Audacity Recovery Tool can stitch it back together.

However, whenever I specify the folder the data is in, it says:

"ERROR

The given path "/Users/Me/Desktop/humandrizzle_data/f/Part 1" does not contain any audio files that could be recovered."

Now, I've split the files up into 'Parts' so that the folder size does not exceed 1GB. There are 600 files in this folder at 1.1MB each, so 660MB. The files are all fine by the looks/sounds of it. But no luck. I tried the PC tool on a friend's PC and had the same problem.

Anyone out there fancy trying to help me? Could I send someone my data via WeTransfer and see if they could try and get it stitched back together? Tried everything I can find online...

Cheers

If you are not already doing so, you may subscribe here: http://audacityteam.org/#announce to receive an e-mail when we release new versions of Audacity.

An obvious possibility is that the AU files are still in folders inside /Users/Me/Desktop/humandrizzle_data/f/Part 1.

If you are still stuck, please open terminal.app in /Applications, then assuming the terminal opens in your home directory, type:

Code: Select all

cd Desktop/humandrizzle_data/f/Part 1

then type:

Code: Select all

ls -R > list.txt

Hit ENTER or RETURN on your keyboard. This saves "list.txt" in /Users/Me/Desktop/humandrizzle_data/f/Part 1 containing a list of the files and folders in that folder.

Repeat for the other folder.

Alternatively follow these steps http://hints.macworld.com/article.php?s ... 9034827358
to give yourself a right-click menu item in Finder "New Terminal at Folder". Then all you have to do is right-click over the required folder, choose that command and run ls -R > list.txt.

Then attach the two list.txt files. Please see here for how to attach files: http://forum.audacityteam.org/viewtopic ... 49&t=64936 .

Hi there

Thanks for getting back to me.

There are no folders in the path I specified, just the .au files.

I will try what you have suggested and report back - many thanks!

Hey,

So I did as you said and this generated one list.txt file. Not sure how I would get two?

Here it is, attached.

Cheers

I thought there were two folders because you said you split it into parts to keep the size under 1 GB.

Your file names are not a consistent sequence where each file name has the same number of letters and numbers. The script probably doesn't like hyphens so remove them.

The first file must be

Code: Select all

e001.au

Then e002.au, e003.au through to e600au.

If the recovery tool does not like the "e", replace it with a "b".

Thanks Gale. I did that and I have had some progress, however it still doesn't seem to be working correctly.

I get this message when I specify the folder - which has 600 sequentially named .au files (with no hyphens) in it:

"115 continuous block(s) of .au files were found.Do you want to recover these files?"

Why does it think there are only 115? When I hit OK/STart Recovery, it processes the file but then creates separate files for 115 of these entries (one for each stereo channel).

I was under the impression it should output just one stereo file?

Please post the current file list (instructions as before).

Please read again my previous post which explains the numbering scheme that is required. The first file must be "b001.au" (if you choose b as a prefix and have up to 999 files), but your first file name is actually "b1.au".

All the file names following "b001.au" must run in sequence with the same number of letters and numbers (in this case a three-digit number base). So the files after b001.au must be:

Code: Select all

b002.au
b003.au
b004.au
b005.au
b006.au
b007.au
b008.au
b009.au
b010.au
b011.au

and so on.
