PLEASE HELP - Open aud project, orphan all files opens blank

[Gale Andrews]

Excellent. Now over five chapters we have all the definitions, conditions and steps to code a terrific rescue tool. Everybody wins!

Well, I'm not sure how many users would follow all this without step-by-step documentation, or whether developers would be rushing to make some script available that worked on the _data folders and the AUP. Also bear in mind this only tests out correctly so far for a recording that was never edited.

I also note that someone on the Wiki ( http://wiki.audacityteam.org/wiki/File_ ... ty_project ) wrote rough steps to split a large failed project into sections using Audacity 1.3.7. However his project appeared to be under the 2^31 limit so it looked as if his problem was something else, and his steps would not recover audio beyond the limit in Audacity 2.x.

Anyway I will post the Windows PowerShell script that rewrites the waveblock start values for all projects after the first. I am told it should work with any version of PowerShell:

Code: Select all

$DebugPreference = "Continue"
[int64]$offset = 0
$indata = Get-Content .wrp2.aup
$outdata = $null
$first = $true
$testitem = [regex]'waveblock start="(?<startingpoint>d*)"'
$rcdCount = 0

foreach ($item in $indata)
{
    if ($item -match $testitem)
    {
        if ($first)
        {
            $first = $false
            $offset = $matches['startingpoint']
        }
        [string]$startstr = -$offset + $matches['startingpoint']
        $item = $item -replace $matches['startingpoint'], $startstr
        $rcdCount++
        Write-Debug -Message "Record $rcdCount"
    }
    $outdata += "$item`n"
}
Set-Content -Path .wrp2mod.aup -Value $outdata -Encoding Ascii -Force
"$rcdCount records processed."

All you need to change in the script is the name of the original project (here "wrp2.aup") and the name of the modified project that is being written (here "wrp2mod.aup").

If you don't want progress messaging, change $DebugPreference to "SilentlyContinue".

If anyone here wants to write a Perl or Python version, that would be great (needed for the other platforms). Otherwise I might look into a Perl version based on a suggestion someone made.

Q win-win for both of us. Your team was excellent!
