Requires Windows Media Encoders and FLAC.

foreach ( $file in dir *.flac )
{
	# Prep input and output filenames 
	$shortName = $file.Name.Substring(0, $file.Name.Length - $file.Extension.Length);
	$wav = $shortName + ".wav";
	$wma = $shortName + ".wma";
	
	# Decode FLAC to WAV
	& 'C:\Program Files (x86)\FLAC\flac.exe' -d $file.Name

	# Encode WAV to WMA Lossless
	cscript "C:\Program Files\Windows Media Components\Encoder\WMCmd.vbs" -input $wav -output $wma -a_codec WMA9LSL -a_mode 2

	# Cleanup
	del $wav;
}

I was reading a blog from a guy on the Monad team and saw this snippet. Monad (or MSH) is the next command-line from Microsoft. It's a dynamic scripting language. It reminds me of some sort of mix of Bash, PHP, Perl and .NET. I just had my ah-ha moment:

foreach ($f in $feeds) { 

    #snip..

    # read the content from $feeduri as XML 

    $wc = new-object System.Net.WebClient 
    $s = $wc.OpenRead($feeduri) 
    $sr = new-object System.IO.StreamReader($s) 
    $rssdata = [xml]$sr.ReadToEnd() 

    # display title 
    write-host $rssdata.rss.channel.title

    # display title and date of each item 

    $rssx.rss.channel.item | 
        foreach-object { 
            write-host "-" $_.title 
            write-host "     " $_.pubDate 
        } 

}

Look at how Monad allows you to use .NET objects. Also note the implicit xml support; you can navigate the DOM as if it were an object ($rssdata.rss.channel.title). Very cool.
