Corrupted aup3 file

Audacity 3 Help Forum

Hi,
We have an issue with a corrupted (possibly) aup3 file.

The error message given is
“Audacity failed to read from a file…”

Also, it gave the following string of code:

{
“timestamp”: 1753029365,
“event_id”: “3499f17feee64b6f935aa1b9138bb7e1”,
“platform”: “native”,
“release”: “audacity@3.7.1”,
“contexts”: {
“os”: {
“type”: “os”,
“name”: “Macintosh”,
“version”: “10.16.0”
}
},
“exception”: {
“values”: [
{
“type”: “File_Error”,
“value”: “Audacity failed to read from a file in /.”,
“mechanism”: {
“type”: “runtime_error”,
“handled”: false,
“data”: {
“sqlite3.rc”: “101”,
“sqlite3.context”: “SqliteSampleBlock::Load::step”
}
}
}
]
}
}

We have tried to open the same file on another Mac.
The error code generated was a bit different.

{
“timestamp”: 1753030837,
“event_id”: “8436ef31360846c1b3673e11e6a899e8”,
“platform”: “native”,
“release”: “audacity@3.7.4”,
“contexts”: {
“os”: {
“type”: “os”,
“name”: “Macintosh”,
“version”: “10.16.0”
}
},
“exception”: {
“values”: [
{
“type”: “File_Error”,
“value”: “Audacity failed to read from a file in /.”,
“mechanism”: {
“type”: “runtime_error”,
“handled”: false,
“data”: {
“sqlite3.rc”: “101”,
“sqlite3.context”: “SqliteSampleBlock::Load::step”
}
}
}
]
}
}

The filesize is a little over one Gigabyte.
Is anyone able to repair aup3 files?
Unfortunately the file contains a lot of important work and would be a tragedy to lose it.
Any help with this very greatly appreciated.

With thanks,
Pip

Hi there,
There are some tools for repairing Audacity projects. They work on Windows and Linux but not Mac. Do you have any tech-savvy friends with a Windows PC?
Failing that, I’ve had a lot of success doing this for other people but I can’t guarantee it. If you’d like me to try, post here and I’ll send you a private message with details on what to do.

I’ve sent a PM to you, Pip.

As AUP3 files are SQLite database files, you can use “DB Browser for SQLite”. It’s available for Windows, Linux and macOS.

Well, you live and learn. Any destructions for doing that? By that, I mean duplicating what the Audacity project tools do?

There’s a few things you can do with DB Browser for SQLite. One very useful “trick” is that if the main “project” table is corrupt, you can replace it with a copy of the “autosave” table.

Note 1: To avoid creating more damage, always work on a copy of the AUP3 file rather than the original.

Note 2: If a project has been corrupted “in the cloud”, it may be sufficient to simply make a copy of the AUP3 file, give it a unique new name, then open it in Audacity.

DB Browser for SQLite can also be used to “compact” a saved project if Audacity’s built-in compaction fails.

It can also be used to check the integrity of the database, and can put the database into a properly “closed” state if Audacity left it open.

Thanks Steve,
Good stuff as usual. The DB Browser prog looks good, if you know what you are looking for - I don’t. So far, I’ve had tremendous success just ‘blindly’ following the steps given for the Audacity project tools. I think there was only one I couldn’t rescue to date. I’ve saved your info’ in a text file so I can find it again later.
Cheers,
Mark B

I used the Audacity project tools to get a working version of the project and sent it back to the user.
