Where can I download FFmpeg for Audacity?

Use this Buanzo FFmpeg for Audacity page for Audacity 3.2 and later. Choose the Windows 64-bit, Windows 32-bit, or macOS installer that matches your Audacity setup.

Is FFmpeg an Audacity plugin?

No. FFmpeg is a library package. Run the installer or point Audacity to the installed FFmpeg library from Preferences or Settings, then Libraries.

Should I download avformat.dll by itself?

No. Download the full FFmpeg shared-library package instead of isolated avformat DLL files from unrelated sites.

How do I verify the Windows 64-bit FFmpeg installer?

Check that the filename is FFmpeg_5.0.0_for_Audacity_on_Windows_x86_64.exe and compare its SHA-256 hash to 9b31e2402cb27c76d56f252e3d6e1bbb4d82526eb93a0ffab7b25193f25de072.

Installation Notes

Make sure your Audacity version is 3.2 or later. On Windows, use the correct installer for 32‑bit or 64‑bit. You may see an error about format60 not being found; you can ignore it.

FFmpeg is not an Audacity plugin. Run the installer or point Audacity to the library in Preferences → Libraries. Do not add FFmpeg in Plugin Manager.

On macOS, the current package is expected to install libavformat*.dylib, libavcodec*.dylib, and libavutil*.dylib. You do not need ffmpeg*.dylib files for Audacity 3.2+.

If these current installers do not match your setup, use the compatibility guide for older downloads.

Note:

Audacity prior to 3.1 only supports avformat-55.dll.
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.
Audacity 3.5 and later also supports avformat-61.dll.
On macOS, this current package uses libavformat*.dylib, libavcodec*.dylib, and libavutil*.dylib. The absence of ffmpeg*.dylib is expected and does not mean the package is wrong.
Older legacy macOS packages may use ffmpeg*.dylib filenames instead.
Make sure you download full FFmpeg copies, not isolated library files. Shared builds are required on Windows because they contain the DLLs Audacity can load.
Different versions of FFmpeg may have different codecs enabled in them. In particular, AMR (narrowband) is not featured in the recommended installer.
You can compare FFmpeg release contents on ffmpeg.org.

About avformat.dll, avformat-61.dll, and FFmpeg libraries

Audacity loads FFmpeg through shared libraries such as avformat-*.dll on Windows and libavformat*.dylib on macOS. Do not download a random isolated DLL from another site. Install the full FFmpeg package from this page, then let Audacity locate the library or browse to it manually from Preferences → Libraries.

If you are searching for avformat-61.dll, use Audacity 3.5 or later and the current Windows installer. If you are on an older Audacity version, check the compatibility guide before choosing a package.

Manual installation

If you have installed FFmpeg from a different source, or installed it in a different location, you will need to tell Audacity where to find it in Preferences → Libraries.

Windows

Go to Edit → Preferences → Libraries.
Click the Locate... button.
If Audacity says it already found FFmpeg automatically, click No and you are done.
If that message does not appear, click Browse... and select the avformat-*.dll file from the FFmpeg folder you downloaded or installed elsewhere.
Click Open, then OK, then OK again to close Preferences.

macOS

Go to Audacity → Settings / Preferences → Libraries.
Click the Locate... button.
If Audacity says it already found FFmpeg automatically, click No and you are done.
If that message does not appear, click Browse... and select the installed libavformat*.dylib file.
Click Open, then close Settings / Preferences.
