A sound file is a digital file that contains audio data, which can include music, speech, or other sounds. These files are stored in various formats, such as MP3, WAV, or AAC, each with its own characteristics regarding quality and file size. Sound files can be played back on computers, smartphones, and other devices that support audio playback. Sound files are commonly used in various applications, including music streaming, podcasts, and video production. They can be created using audio recording software or captured directly from microphones. Additionally, sound files can be edited and manipulated using digital audio workstations (DAWs) like Audacity or Pro Tools.
