MIDI vs. Digital Audio — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on November 30, 2023
MIDI (Musical Instrument Digital Interface) conveys musical notes and control signals, while Digital Audio represents actual sound waves in a digital format.

Key Differences
MIDI and Digital Audio both function within the realm of electronic music but serve divergent purposes and possess distinct technical characteristics. MIDI, essentially a communication protocol, does not store sound but transmits musical information like pitch, duration, and velocity, enabling electronic devices like synthesizers and computers to interact and generate sound. On the other hand, Digital Audio encapsulates real sounds, converting acoustic sound waves into digital signals which can be manipulated, stored, and reproduced, presenting actual auditory content.
Thus, MIDI thrives on instructing devices on how to produce sounds, offering immense control over elements like pitch, tempo, and timbre without containing any sonic information itself. Contrarily, Digital Audio captures, stores, and reproduces sound, serving as a literal representation of audible signals in a digitalized form, providing tangible audio playback but with less flexibility in altering musical elements dynamically.
MIDI's efficacy lies in its low data usage, ability to alter musical parameters dynamically, and facilitating intricate digital music compositions by orchestrating numerous instruments and channels with detailed instructions. Conversely, Digital Audio, being an authentic representation of sound, excels in capturing and reproducing nuances of audio, including voice and acoustic instruments, providing rich and accurate auditory experiences.
While MIDI provides an avenue for controlling and manipulating musical elements flexibly across varied instruments, it necessitates external sound modules or synthesizers to convert its data into audible sound. Digital Audio, alternatively, does not demand external sound sources for playback, as the stored files contain the actual audio, but does not inherently provide extensive manipulative control over individual musical parameters.

Common Curiosities
What is MIDI commonly used for?
MIDI is widely used for electronic music production and controlling musical devices.
Can Digital Audio files be played without additional instruments?
Yes, Digital Audio contains actual sound data and can be played back directly.
Can MIDI control multiple instruments simultaneously?
Yes, MIDI can control and orchestrate multiple instruments and channels concurrently.
What’s a key advantage of Digital Audio?
Accurate recording and playback of actual sound, including nuanced audio details.
Which is generally larger in file size, MIDI or Digital Audio?
Typically, Digital Audio due to containing actual sound data.
Does MIDI contain actual sound data?
No, MIDI contains instructions for generating sound but no audio data.
Is MIDI suitable for recording vocals?
No, MIDI does not record sound and therefore is not suitable for vocals.
How does Digital Audio represent sound?
Digital Audio represents sound waves as digital data, enabling recording and playback.
Can you manipulate musical elements like pitch in Digital Audio?
Yes, but it involves altering the waveform directly, not dynamically as MIDI does.
How is sound quality affected in Digital Audio when altering pitch?
It can degrade, as altering pitch changes the speed of the waveform playback.
