Key Difference: AIFF is an abbreviation of Audio Interchange File Format. On the other hand, MIDI is an abbreviation of Musical Instrument Digital Interface.

AIFF stands for Audio Interchange File Format; it is also an audio file format. In 1988, the format was developed by Apple Computer. The leading file format is a standard AIFF along with SDII and WAV, and is mostly used by businessmen or professionals. It is also an uncompressed file, and is lossless. It uses more disk than any uncompressed file like MP3.

However, AIFF is developed by Apple so it works best for Apple Macintosh systems. Same like WAV, AIFF files also offer a lot of flexibility in editing, copying, changing file formats, and other productions activities. But yes, if one needs to edit the audio, then he should not store the file in these formats, otherwise he will not be able to edit it.

MIDI stands for Musical Instrument Digital Interface. A MIDI is a file that records music and controls the notes of each instrument, finishes, how loud, what note of the scale is, etc. It can be any MIDI instrument. MIDI is pronounced as middy. MIDI was first announced in 1982, and by December it actually appeared on an instrument. After that time the electronic musical devices have increasingly became very common. It is used in instruments that have sound cards, synthesizers and sound generators that control music. It is a format that is universally accepted and if one synthesizer has produced music using MIDI format, then that can be modified with another synthesizer.
