PowerShell Audio is a PowerShell-driven interface for converting and tagging audio / music files. It is available under the Lesser GPL (v3) license, and is for Windows use only.

PowerShell Audio has been replaced with AudioWorks, which offers many enhancements - including Linux and MacOS support!

Features

• A unified interface to popular codecs (see Supported Formats).
• Fast and highly concurrent ("multi-threaded") for modern, multi-core systems.
• ReplayGain integration:
  • Batch-analyze thousands of files quickly,
  • save the results to disk,
  • convert to Apple SoundCheck format,
  • or apply the changes directly during encoding.
• Metadata preservation between formats, including cover art.
• PowerShell interface brings powerful integration and scripting capabilities.
• API is open-source and extensible.

Supported Formats

• FLAC
• Ogg Vorbis
• MP3 (LAME)
• Apple AAC
• Apple Lossless
• WAV

Supported languages

• English (translation help wanted!)

Example usage

This command simply converts a folder full of FLAC files into MP3s:

   Get-AudioFile *.flac  | Export-AudioFile "Lame MP3" C:\Output

To get a list of available encoders:

   Get-AudioEncoderInfo

To get information about the Lame encoder, including the default and available settings:

   Get-AudioEncoderInfo "Lame MP3"

Add ReplayGain 2.0 to your entire FLAC library, treating each directory as a separate album:

   Get-ChildItem C:\Users\Myself\Music -Directory -Recurse | % { $_ | Get-ChildItem -File -Filter *.flac | Measure-AudioFile "ReplayGain 2.0" -PassThru | Save-AudioFileMetadata }

Convert your whole FLAC library to VBR AAC, with SoundCheck tags calculated from album ReplayGain information:

   Get-ChildItem C:\Users\Myself\Music -Filter *.flac -Recurse | Get-AudioFile | Export-AudioFile "Apple AAC" "C:\Output\{Artist}\{Album}" -Name "{TrackNumber} - {Title}" -Setting @{AddSoundCheck = "Album"}

Convert your whole FLAC library to VBR MP3, with ReplayGain directly applied to the resulting volume levels:

   Get-ChildItem C:\Users\Myself\Music -Filter *.flac -Recurse | Get-AudioFile | Export-AudioFile "Lame MP3" "C:\Output\{Artist}\{Album}" -Name "{TrackNumber} - {Title}" -Setting @{ApplyGain = "Album"}

Convert your whole FLAC library to VBR AAC, with embedded cover art retrieved from images located in each subdirectory. Embedded images are scaled and/or converted to JPEG for efficiency, where necessary:

   foreach ($directory in Get-ChildItem C:\Users\Myself\Music -Directory -Recurse)
   {
       $cover = $directory | Get-ChildItem -File -Include *.png,*.jpg | Get-AudioCoverArt | Convert-AudioCoverArt -MaxWidth 500 -ConvertToLossy
       $files = $directory | Get-ChildItem -File -Filter *.flac | Get-AudioFile
       if ($files -and $cover)
       {
           $files | Set-AudioFileCoverArt $cover
       }
       $files | Export-AudioFile "Apple AAC" "C:\Output\{Artist}\{Album}" -Name "{TrackNumber} - {Title}"
   }
