AAC Is Not Natively Supported by Audacity

First of all, let's begin with the audio file formats supported by Audacity. Roughly speaking, Audacity inherently supports lossless WAV, AIFF, FLAC files and lossy Ogg Vorbis, MP2, MP3 files.

Advanced Audio Coding (AAC), a lossy digital audio compression format, is obviously not on the list. Therefore, Audacity will pop up an error message when you import AAC files encoded in .aac, .m4a, .m4b, .m4r extensions. Nevertheless, the following part will show you how to tackle this issue.

How to Install FFmpeg Library for Audacity AAC Import/Export?

The optional FFmpeg library allows Audacity to import and export AAC-encoded files that are not DRM-protected, but due to software patents, it cannot be included or distributed from Audacity's own website. That is to say, in addition to Audacity itself, there's one more step to download and configure the third-party FFmpeg Library. Before we get started, you're advised to update Audacity to the latest version with over 160 fixes from the official website: https://www.audacityteam.org/.

For Windows users, open https://lame.buanzo.org/#lamewindl, navigate to "FFmpeg for Windows and latest Audacity versions" part and you're allowed to download either "FFmpeg recommended ZIP option" or "FFmpeg Binary for Windows" for Audacity 2.0.6 and later versions.


1. FFmpeg Binary for Windows

Right-click on "ffmpeg-win-2.2.2.exe" and select "Save link as" to download this .exe file. Simply run "ffmpeg-win-2.2.2.exe" installer and complete the installation, FFmpeg Library will be automatically installed and configured in Audacity. If it doesn't work, try the ZIP option and manually locate FFmpeg in Audacity as follows.


2. FFmpeg RECOMMENDED ZIP OPTION

When you have downloaded the compressed package "ffmpeg-win-2.2.2.zip" file, create a new folder anywhere on your computer, unzip and extract all files into it. Next, launch Audacity, click "Edit" menu and open "Preferences" window. Navigate to "Libraries" on the left sidebar, click on "Locate" button and locate the "unzipped folder that contains FFmpeg", select "avformat-55.dll" file. Then click "OK" and save the preferences.


For Mac or GNU/Linux users, please check the similar instructions on Installing FFmpeg for Mac or Installing FFmpeg for Linux.
