QuickTime is an extensible multimedia framework powered by Apple Inc., which has the feature of handling various formats of digital video, picture, sound, panoramic images, and interactivity.

There are several options for converting audio files in OS X, but OS X also includes an audio converter built into Finder. First you should be noted that this method has some limitations compared to other audio converters. It can only accept AIFF, AIFC, Sd2f, CAFF, or WAVE files and can only output to four AAC presets. However, these presets cover a range of uses and should accommodate most Mac users who manage their music in AAC formats.
4. Command Line
As we know, command line contains a few tools for working with your music files. Although this option is powerful, it is the most complicated of the bunch. You may even don’t attempt to go into all the details on how it works because you don’t know them all! You can specify all sorts of options to control the input and output formats, such as “mp4f” -d “aac@44100″ /System/Library/Sounds/Basso.aiff ~/Desktop/basso_converted.mp4”.
