Key Differences
The MIDI File Format stores musical performance information like pitch, duration, and intensity of notes, but it doesn't contain any actual audio data. It's like a digital sheet music that instructs electronic devices on how to generate sounds. The MP3 Audio File Format, in contrast, stores compressed audio data that can be played back on a wide range of devices, containing the actual sound.
MIDI files are small in size as they contain only instructional data, not sound. This format is ideal for editing individual notes, changing instruments, and adjusting tempo without affecting audio quality. MP3 files are larger because they contain complex audio data, but they are still significantly smaller than uncompressed formats like WAV due to their compression techniques.
When a MIDI file is played, it triggers the sounds from the electronic instruments or software it's connected to, meaning the final output can vary greatly depending on the equipment used. MP3 files, however, play the same on any device as they contain specific audio information.
MIDI File Format is primarily used in music production, where detailed control over each aspect of the music is essential. It allows composers and producers to manipulate various musical components independently. The MP3 Audio File Format is widely used for music distribution and playback, valued for its balance of audio quality and file size.
The versatility of the MIDI File Format makes it a staple in interactive environments like video games, where dynamic music control is necessary. MP3 files, being straightforward audio recordings, are not suitable for such applications but are ideal for general music listening purposes on digital media players and streaming platforms.
