The phrase refers to the process of extracting the audio track from a video-sharing platform and converting it into a widely compatible audio file format, such as MP3. Crucially, this process also involves retaining or incorporating the visual representation, frequently a reduced-size image, associated with the original video. For instance, one might acquire an audio file of a musical performance and simultaneously preserve the album art or a representative frame from the video.
The primary value lies in enabling offline accessibility of audio content. By separating the audio from its visual component, the user gains the flexibility to listen to content on devices with limited bandwidth or while multitasking. The accompanying image provides a visual identifier, simplifying organization and playback on devices or media players where visual browsing is prominent. The functionality gained popularity alongside the proliferation of portable audio players and the increased consumption of user-generated content.
