converts other sound formats to mp3 - can't remember where I grabbed this from but put it together and requires VLC

ConvertTo-MP3.ps1

function ConvertToMp3( $file, [string] $vlc = 'C:\Program Files\VideoLAN\VLC\vlc.exe') {      
  PROCESS {            
    $codec = 'mp3';        
    $oldFile = Get-Item $file;

    $newFile = $oldFile.FullName.Replace($oldFile.Extension, ".$codec");

    &"$vlc" -I dummy "$oldFile" ":sout=#transcode{acodec=$codec,vcodec=dummy}:standard{access=file,mux=raw,dst=$newFile}" vlc://quit | out-null;

    #Only remove source files when you are sure that the conversion works as you want          
    #Remove-Item $oldFile;
  }  
}


$vlc = 'C:\Program Files\VideoLAN\VLC\vlc.exe'
$codec = 'mp3';        
$oldFile = Get-Item 'C:\tmep\Sound recordings\Recording (2).m4a'

$newFile = $oldFile.FullName.Replace($oldFile.Extension, ".$codec");

&"$vlc" -I dummy "$oldFile" ":sout=#transcode{acodec=$codec,vcodec=dummy}:standard{access=file,mux=raw,dst=$newFile}" vlc://quit | out-null;
