Exporting an Audacity File as an MP3 File

After you've recorded in Audacity, you'll able to save your work as an Audacity file. When you attempt to export an Audacity file as an MP3 file, which is a good-quality compressed file, you will receive a message stating that Audacity needs the file lame-enc.dll to create MP3s.

Click on Download. You will need to download the LAME encoder only one time and after that, you'll be able to create MP3 files out of your Audacity recordings just with a few clicks.

'Locate Lame Encoder' Window

Next, you will be provided with the following instructions:

Because of software patents, MP3 encoding software cannot be distribute with Audacity together. Follow these instructions to use the free LAME encoder to export MP3 files with Audacity.

Windows

  1. Go to the LAME download page.
     Left-click this link, do not right-click
  2. Under "For Audacity on Windows", left-click the link "Lame v3.98.2 for Audacity on Windows.exe" and save the file anywhere on your computer.
  3. Double-click "Lame_v3.98.2_for_Audacity_on_Windows.exe" to launch it (you can safely ignore any warnings that the "publisher could not be verified").
  4. Follow the Setup instructions to install LAME for Audacity, and do not change the offered destination location of "C:\Program Files\Lame for Audacity".

You should now be able to export MP3s without any further configuration. For troubleshooting go to the Installation and Plug-Ins page of the Audacity Web site.

Mac OS 9 or X:

  1. Go to the LAME download page.
  2. Download either "Lame Library v3.98.2 for Audacity on OSX.dmg" or "LameLib-Carbon.sit", as required.
    Lame Library v3.98.2 for Audacity on OSX.dmg
  1. When you have finished downloading, double-click the .dmg to mount it, then go to the Finder (in Safari, "Lame Library v3.98.2 for Audacity.pkg" will be extracted automatically after downloading).
  2. Double-click "Lame Library v3.98.2 for Audacity.pkg". This will install the LAME binary "libmp3lame.dylib" in /usr/local/lib/audacity.
  3. The first time you use the "Export as MP3" command, Audacity will ask you where libmp3lame.dylib is saved - navigate to /usr/local/lib/audacity, select it and click "Open" then "OK".
    LameLib-Carbon.sit
  1. When you have finished downloading, extract the files with Stuffit Expander or similar (this may happen automatically).
  2. Save the file called "LameLib" anywhere on your computer.
  3. The first time you use the "Export as MP3" command, Audacity will ask you where LameLib is saved - navigate to that location, select LameLib and click "Open" then "OK".
