How to Fix FFmpeg library missing issue in Audacity

Do you ever get an error message saying ” File is an Advanced Audio Coding file. Without the optional FFmpeg Library Audacity cannot open this type of file” while working and editing the Audio Clips and importing them into Audacity? Most users who have lately used Audacity software have encountered this issue with the “FFmpeg Library not found“.
This issue occurs because Audacity does not support all audio formats, and we must convert a specific file type into an Audacity-compatible format. This is not a good solution because audio format conversion can degrade audio quality and results in much larger or smaller file sizes. Let us see how to fix this error in Audacity in this article.
 

How to fix the error saying ” Importing FFmpeg Library missing”

Installing the optional FFmpeg Library will allow Audacity to import and export a far wider range of audio formats, including M4A (AAC), AC3, AMR (narrowband), and WMA as well as audio from most video files can also be imported. Let us see how we can do this.

Step 14: Audacity can now open/import and edit large-range audio formats without any problem.

 

Sometimes you may still get the same error, even after installing the FFmpeg library. This means that you have installed FFmpeg when Audacity is Open or you have installed it to a non-default location ( Directory) in your system. Audacity will now ask you to configure Preferences to locate the FFmpeg library. This is done by following the steps given below.

Step 1: Open Audacity, click on Edit > Preferences , or simply Click Cltr+P.

Edit 

Step 2: Click on Libraries > Locate.

Step 3: If a Success notice appears indicating that Audacity has now automatically detected valid FFmpeg libraries and asks you to identify them manually, Click on NO.

NOTE: Most of the time FFmpeg library will be installed in the correct location only.

Step 4: But, again if a message saying ” Locate FFmpeg ” appears, it means that we need to locate the “avformat-55.dll“.To do so, click on Browse to locate the folder.

Step 5:  Now, we need to go to the appropriate folder that contains FFmpeg.

Once you have downloaded, installed, and located the directory containing FFmpeg and you still get the message        “FFmpeg Not found“, it means you have installed the wrong libraries. Now you need to download the correct libraries based on your operating system.
