Audicity2.3.3は64bitになったのでFFmpegも64bit版を使えとのことです。

The optional FFmpeg library allows Audacity to import and export a much larger range of audio formats including M4A (AAC), AC3, AMR (narrow band) and WMA and also to import audio from most video files.

Because of software patents, Audacity cannot include the FFmpeg software or distribute it from its own websites. Instead, use the following instructions to download and install the free and recommended FFmpeg third-party library.

Advanced usage: If you already have 64-bit Audacity-compatible FFmpeg 2.2.x or 2.3.x shared libraries in the system PATH, Audacity will use those as long as you do not install FFmpeg from the links below and as long as you do not specify the FFmpeg you want Audacity to use in Libraries Preferences.

Audacity 2.3.1 on Mac is now a 64-bit application.This means that if you are a user of previous Audacity versions on Mac and had installed the optional FFmpeg library then you must now install the 64-bit versions of the FFmpeg library, otherwise your imports and exports that depend upon FFmpeg will no longer work.

Installing the 64-bit FFmpeg library will not overwrite or delete your 32-bit FFmpeg library if you have one installed.
