I'm getting a feeling of deja vu, as I have the vague recollection that I tried doing this same thing years ago on an older Mac, and I'm not sure I had any success with it then, either. In ~/Library/Application Support/audacity I see libs > libmp3lame64bit.dylib Error Importing message: It's an 'Advanced Audio Coding file, I need the optionalFFmpec library. It says 'The installation was successful.'īack to step 1. I double-click the installer: lame_64bit_osx.pkg. I'm taken to 'RECOMMENDED download:lame_64bit_osx.pkg' I'm taken to: 'Installing the FFmpeg Import/Export Library on Mac' 'For full instructions please see Installing FFmpeg for Mac.' Under 'How do I download and install the FFmpeg Import/Export Library?' I see 'Mac: See the FFmpeg installation section'

Up comes 'FAQ:Installation, Startup and Plug-ins.' I click the words 'FFmpeg library' which is a link. Under Importing Audio in the page that comes up, I see 'You can install the optional FFmpeg library to import a much larger range of audio formats including AC3, AMR(NB), M4A, MP4 and WMA' I click the little question mark in the error dialog.

I am trying to import an m4a file into Audacity. This will not affect the recommended builds of FFmpeg for Windows and Mac OS X which. This is getting pretty complicated, but I'll try to write this as briefly as possible. 6 but applications other than Audacity may not see all the tags.
