Audacity natively supports common audio formats such as WAV, AIFF, Ogg Vorbis, FLAC, MP2, and MP3. However, it does not support M4A, AAC, or other Apple Lossless Audio Codec (ALAC) containers by default.
To import and export more audio formats in Audacity, you need to install the FFmpeg library, which significantly expands format compatibility.

This makes FFmpeg an essential tool for users who work with a wide range of audio files.
