Digital audio files are electronic files that store sound in a format that can be easily played back on computers, smartphones, and other devices. These files convert sound waves into binary data, which is a series of 0s and 1s. Common formats include MP3, WAV, and AAC, each with different qualities and file sizes. These files can be created from recordings of music, speech, or any other sounds. They allow for easy sharing and distribution over the internet, making it simple to access audio content through platforms like Spotify or Apple Music. Digital audio files have revolutionized how we consume and enjoy sound.
