Maybe 'import' is not a exact word.
Audio editors (Audacity, SoundForge, etc.) work with
uncompressed audio like wav files are. Then Audacity 'read' wav files without any operation.
Compressed audio, lossless (Flac, etc.) or lossy (Ac3, Aac, etc.), must be decoded before to be edited. Then Audacity need 'decode' compressed formats, and can use ffmpeg (and others decoders) automatically to 'import' these formats.
Many Audio editors have decoders, inside or by plugins, to decode compressed formats.

So, is there any difference between these two methods?:
original sound -> import -> edit -> export
original sound -> convert to lossless wav -> edit -> export

Is the same. With Audacity you can decode and read some compressed formats using ffmpeg.
But you can decode these formats to wav with others decoders (eac3to, BeHappy, ...) and after read the wav with Audacity.
