A MID (or MIDI) file describes music data in the Musical Instrument Digital Interface technical standard. Unlike other audio formats like MP3, it specifies the individual music notes, their duration and loudness, as well as the instruments used. Because of that, a MIDI file may sound differently on different systems.
In order to make it consistent, you can convert it to another audio format.

AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.
