AU Files Not Recognized by Repair Tools But Open in Audacity

[Gale_Andrews]

@asloane

city 2.0.5 was recording live from a mic connected to a USB Soundcard (Focusrite) when Win 7 froze necessitating a system reboot.

Why did it freeze? Did you run out of power? If Windows is freezing you need to find out why.

Do you have the correct drivers and firmware for the Focusrite?

@asloane

Audacity offered to recover the recording but could not

What exactly happened? Was the recording silenced? If there were errors, exactly what did they say? Did you look at Help > Show Log… ?

@asloane

and suggested Import Raw Data.

The Automatic Crash Recovery dialogue does not suggest Import Raw Data.

@asloane

The AU files are audible after importing as Raw Data and as Audio. Using Import Raw Data some files sound strange and have a wave form which does look nor sound like speech.

If you mean they were too slow or fast, try setting the track rate to the rate the project was. You can do this at “Set Rate” in the Track Drop-Down Menu ( Audacity Manual ).

@asloane

The files were renamed for use with aud_recover.exe but the resulting file had similar issues as Import Raw Data, i.e. the waveforms were not like speech.

audacity_recovery.exe was used but its error message was that it could not find any files to be recovered.

Then you did not rename the files correctly.

@asloane

There are 777 files. Each file can be spliced in Audacity and/or converted in WAV files but this is laborious. Can anyone suggest a less labour intensive method?

Why do you need to do this? What is the problem with the autosave file at UsersAppDataRoamingAudacityAutoSave ? If you can still launch Audacity and have it offer recovery, please try that, then attach the log from Help > Show Log… and attach the autosave file (as above).

To see the autosave file, you may need to set Windows to show hidden files and folders. See here for how to do that: How to see hidden files in Windows .

To attach files to your reply, please see: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1 .

You can regenerate a project file from the AU files using an experimental script, but you would have to install Python and be comfortable using a command prompt. It would be easier to use the autosave file.
