The expression relates to tools or services enabling the transformation of online video content, particularly from a video-sharing platform, into a specific audio file format. This typically involves extracting the audio stream from a video hosted on a popular website and converting it into a widely supported audio format for offline listening or use. As an example, a user might employ such a service to isolate the soundtrack from a music video found on a particular video-sharing site, resulting in an audio file on their local device.
The utility of this kind of service stems from several factors. It provides a means for users to acquire audio content for personal use without necessarily requiring a subscription to a streaming platform or purchasing the original video file. Furthermore, it can be a convenient way to obtain audio from sources where the primary focus is on video presentation, such as lectures, interviews, or performances. The rise of such tools coincided with the proliferation of online video sharing and the increasing demand for portable audio files, predating widely available streaming services.
