mp3 file will not import

I have made a recording and have been given the various takes as mp3 files. I now need to trim and edit on Audacity. However, although Audacity normally imports mp3 files without any problems, these files import as a brief bit of noise. The files play fine on windows media player. What could the problem be?

It’s not an MP3. It’s an MP4 (AAC). (Thanks for attaching the file! I checked it with MediaInfo.)

Rename the file to .MP4 or .AAC, And if you haven’t done so already, [u]Install FFmpeg for Audacity[/u].
