What is an MIDI file?

MIDI (Musical Instrument Digital Interface) is a format that records musical performance instructions, widely used in electronic music production, arrangement, and music education. MIDI files do not contain audio data but are converted to actual audio using soundfont libraries (e.g., FluidSynth). Supports multi-format conversion via FFmpeg. Audio-to-MIDI requires pitch detection tools for music production and arrangement. MIDI files are small in size, easy to edit, and suitable for music creation and real-time performance.
