Installing FFmpeg
FFmpeg allows you import/export additional audio file formats into/from Audacity
Due to patent restrictions, FFmpeg cannot be distributed with Audacity itself. However, FFmpeg is required to import and export a variety of audio formats, including M4A and WMA.
Note: In previous versions of Audacity, LAME was required to export MP3 files. It is now included with Audacity by default on Windows and macOS. Make sure you are using the latest version of Audacity if you're getting any LAME errors.
You can download and install FFmpeg as follows:
Windows
macOS
Linux
- 1.Download the FFmpeg installer from https://lame.buanzo.org/ffmpeg.php For most computers, the 64-bit Windows version is correct.
- 2.Run the installer. You can ignore the "unknown publisher" warning.
- 3.Read and accept the license
- 4.Select the location to install FFmpeg. By default FFmpeg will be installed into C:\Program Files\FFmpeg for Audacity
- 5.Finish the installation
- 6.Restart Audacity
Audacity should now automatically detect FFmpeg and allow you to use it.
If you prefer a manual installation of FFmpeg you can download a ZIP file from a different source:
Note:
- Audacity 3.1 and later supports avformat-55.dll, avformat-57.dll and avformat-58.dll. Audacity 3.2 and later also supports avformat-59.dll. Audacity 3.3 and later also supports avformat-60.dll. You can check which dll is in which FFmpeg release here.
- Make sure you download full FFmpeg copies, not just the avformat-*.dll's individually. Further, make sure to download or build the shared versions as only those contain .dll's.
- Different versions of FFmpeg may have different codecs enabled in them. In particular, AMR (narrowband) is not featured in the recommended installer.
If you have installed FFmpeg from a different source, or installed it in a different location, you'll need to tell Audacity where to find it. To do this:
- 1.Go to Edit > Preferences > Libraries
- 2.Click on the Locate... button.
- 3.If the following message appears, Audacity has automatically identified FFmpeg:
You can click No as Audacity already knows where to find FFmpeg.If this message does not appear, proceed with the next steps. - 4.In this dialog window, click Browse... to locate the avformat-*.dll from the FFmpeg folder you downloaded/installed elsewhere
- 5.Once you've found it, click Open, then OK, then OK again to close the preferences.
This is a universal binary installer. It automatically matches your system architecture.
- 1.
- 2.When you have finished downloading, open the .pkg. You will be guided through the installation
- 3.Click through the steps in the installer.
- On some Macs the process may look as though it has stalled on "Validating packages" - just be patient and wait for it to complete.
- 4.Restart Audacity if it was running when you installed FFmpeg then Audacity should detect FFmpeg automatically.
If you have problems with Audacity detecting FFmpeg, follow the steps below to manually locate FFmpeg.
One way to install an FFmpeg version that matches your system architecture is using homebrew. You can install it through the Terminal.app by typing in:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
And once you have Homebrew, the following command installs FFmpeg:
brew install ffmpeg
Audacity should now automatically detect the installation after a restart. If not, follow the steps of a manual installation.
You can download or compile FFmpeg yourself as described here: https://trac.ffmpeg.org/wiki/CompilationGuide/macOS
Note:
- Audacity 3.1 and later supports avformat 55, 57 and 58. Audacity 3.2 and later also supports avformat 59. Audacity 3.3 and later also supports avformat 60.
- Make sure to download or build the shared versions (with .dylib's) as only those can be used by Audacity.
- Different versions of FFmpeg may have different codecs enabled in them. In particular, AMR (narrowband) is not featured in the recommended installer.
If you have installed FFmpeg from a different source, or installed it in a different location, you'll need to tell Audacity where to find it. To do this:
- 1.Go to Audacity > Preferences > Libraries
- 2.Click on the Locate... button.
- 3.If a "Success" message appears, Audacity has successfully found FFmpeg. You can click No as Audacity already knows where to find FFmpeg.If this message does not appear, proceed with the next steps.
- 4.In the "Locate FFMPEG" dialog, click Browse... to locate the avformat-*.dylib from the FFmpeg folder you downloaded/installed elsewhere.
- 5.Once you've found it, click Open, then OK and OK again to close the preferences.
If you're using an Apple Silicon ("M1", "M2") system, make sure that your FFmpeg and Audacity architectures match:
- arm64 (Apple Silicon) Audacity needs arm64 FFmpeg,
- x86_64 (intel, also known as x64 and amd64) Audacity needs x86_64 FFmpeg.
Additionally, make sure you're using the latest version of Audacity.
On Linux, you generally can install FFmpeg as well as LAME through the package manager. You can use the following command in your Terminal/Console to install it:
Debian, Ubuntu, Pop_OS!, Mint | sudo apt install ffmpeg lame |
Fedora, Redhat, CentOS | sudo dnf install ffmpeg lame |
Arch, Manjaro | sudo pacman -Syu ffmpeg lame |
Once you have installed FFMPEG and LAME, restart Audacity. It will automatically try to detect them.
Caution: Audacity supports FFmpeg's libavformat in version 55 (all Audacity versions), 57 and 58 (Audacity 3.1+), 59 (Audacity 3.2+) and 60 (Audacity 3.3+). If your distribution ships with a different version, it may not get detected, or may not work correctly. In that case, you may need to uninstall FFmpeg again and make a shared build of a supported version from source.
If your FFmpeg or LAME installation didn't get detected, you'll need to tell Audacity where to find it. To do this:
- 1.Go to Edit > Preferences > Libraries
- 2.Click on the Locate... button of the relevant library.
- 3.If a "Success" message appears, Audacity has successfully found the library. You can click No as Audacity already knows where to find the library.If this message does not appear, proceed with the next steps.
- 4.In case of FFMPEG: In the "Locate FFmpeg" dialog, click Browse... to locate the libavformat.so.* from the FFMPEG folder you downloaded/installed elsewhere. In case of LAME: In the "Locate LAME" dialog, click Browse... to locate the libmp3lame.so that you downloaded/installed elsewhere.
- 5.Once you've found it, click Open, then OK and OK again to close the preferences.
