LAME 3,100 mp3 for Apple Silicon (arm64)

By | April 5, 2021

There are still times when I need to be able to encode audio files to mp3. Since it is usually much faster to use Terminal than to import the audio file in, for example, Logic Pro and export from there, I compiled LAME optimized for Apple Silicon (M1, arm64).

Since there may be some international interest, I write the rest in English.

In the package:

  • LAME command-line encoder, for encoding audio files in the command-line

  • libmp3lame.dylib – used by for example Audacity when exporting to mp3
