The FFmpeg project recommends Windows builds from the following sources:

  • https://www.gyan.dev/ffmpeg/builds/
  • https://github.com/BtbN/FFmpeg-Builds/releases

On one of these pages, select a “shared” build so the DLL will actually be there. It will be located in the “bin” folder. However, the current version is 57. It may or may not work with Audacity.

Also keep in mind to pick the correct choice from 32/64 bit: It needs to match Audacity’s “bitness”. You can look in Task Manager to find out whether it’s a 32-bit process.

On the official Audacity wiki, theres a section on how to get FFmpeg. It directs you to this page: http://lame.buanzo.org/#lamewindl You can find the required FFmpeg version there.

Downloads from that page are terribly slow, so I’ll provide a mirror: http://download.futuretech.in/ffmpeg-win-2.2.2.zip

Unfortunately, there’s no checksum on the original page, so I cannot prove that my mirror isn’t tampered with. Use it at your own risk.

Why does it say that Lame mp3 is a trojan and PUP
What AV are you using? The answer is one of two things, the LAME encoder you DL'd is infected or (more likely) your AV is wrong. Did you get it from here? https://lame.buanzo.org/ More on reddit.com
