Audio

Audio is the electronic or digital representation of sound, or the vibrations that propagate through a medium (such as air) and are perceived by the human ear. It refers both to the sound signal itself and to the technology used to record, modify, transmit, and reproduce it.

What is it for / Why is it important

Audio is a fundamental component of human communication and multimedia experiences. It serves to convey information (speech), evoke emotion (music), create atmosphere (sound effects), reinforce a message (advertising jingles, voice-overs), and improve usability (interface sounds). In marketing, film, radio, podcasts, and gaming, audio is crucial for engaging audiences and conveying meanings that images alone cannot express.

When to use it / In what context is it useful?

Audio is present in countless contexts:

• Media: Radio, podcasts, audiobooks.

• Audiovisual: Soundtracks and soundtracks for films, videos, television.

• Music: Recording, production, and playback of music.

• Marketing: Jingles, radio spots, voice-overs, sonic branding.

• Technology: Sound effects (SFX) in video games and apps, voice interfaces, telephony.

• Events: Sound design for live shows, conferences.

Practical example

• The vocal track of a podcast you're listening to.

• The background music and sound effects (footsteps, doors slamming) in a movie.

• The notification "ding" on your smartphone.
