Accessing Audio File Metadata

Question

Is there a way to read/write audio file (mp3, flac, wav) metadata using Microsoft PowerShell? I just need a dll with this functionality so that I can call the functions from within the PowerShell script.

Answer 1

I plagiarized this code and updated it a little bit. The original code is here: mp3-tag

Function Get-MP3MetaData {
    [CmdletBinding()]
    [Alias()]
    [OutputType([Psobject])]
    Param
    (
        [Parameter(Mandatory = $true, ValueFromPipeline = $true)]
        [String] $Directory
    )

    Begin {
        $shell = New-Object -ComObject "Shell.Application"
        $PropertArray = 0, 1, 2, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 27, 28, 36, 220, 223
    }
    Process {
        Foreach ($Dir in $Directory) {
            $ObjDir = $shell.NameSpace($Dir)
            $SearchDir = $Dir + "\*"                # when Get-ChildItem uses -Include the Path must end with *
            Get-ChildItem $SearchDir -File -Include *.mp3,*.mp4 |
                ForEach-Object{
                    $ObjFile = $ObjDir.parsename($_.Name)
                    $MetaData = [ordered]@{}
                    Foreach ($item in $PropertArray) { 
                        If ($ObjDir.GetDetailsOf($ObjFile, $item)) { #To avoid empty values
                            $MetaData[$($ObjDir.GetDetailsOf($MP3, $item))] = $ObjDir.GetDetailsOf($ObjFile, $item)
                        }
                    }
                    $MetaData['Directory'] = $Dir
                    $MetaData['Fullname'] = (Join-Path $Dir $_.Name -Resolve)
                    $MetaData['Extension'] = $_.Extension
                    [PSCustomObject]$MetaData
                }
        }
    }
    End {
    }
}

# Example of how to use the function:
#ForEach($item in ("D:\Powershell\Tutorials\4_DSC" |Get-MP3MetaData)){
#    $NewName = [regex]::Replace($(($item.Title).Split(":")[1].Trim() + $item.extension),"[*(/)\\&#]",{''})
#    $Oldname = $item.Fullname
#    Rename-Item -LiteralPath $item.Fullname -NewName $NewName -Force
#}
