Audio files come in a number of different file formats. Some are lossy such as AAC and MP3, which helps save space when compared to original files. Some are lossless like Apple Lossless, FLAC, which can be converted back to their original form without the loss of a single bit. There are still some uncompressed ones such as WAV or AIFF, which represent the exact data from a CD or a master.
It's likely that you might purchase a music or song from iTunes or Amazon online store and want to transfer and enjoy them on your iPhone, iPod, iPod or Android devices, or there are some audio tracks on your favorite movies that you want to extract for burning to CD.
To convert audio files to another audio file format, you can just use iTunes, which supports AAC, Apple Lossless, MP3, AIFF, and WAV files. You can convert to or from any of these formats as needed. If you have some AAC files you bought from the iTunes Store (DRM-free, as all recent iTunes music comes) and want to play them on a device that only supports MP3 files; iTunes can do this for you.
In terms of extracting audio from video, iMovie will be your perfect solution. Launch iMovie, choose File > New Project to create exactly that, and select File > Import > Movies. Add your movie to a project. Choose Share > Export Using QuickTime. In the Save Exported File As window that appears, choose Sound to AIFF from the Export pop-up menu and click Save to create an AIFF audio file.
