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.
