The phrase refers to the process of extracting audio from video content hosted on the YouTube platform and converting it into the MP3 audio format using web-based services. An example includes utilizing a website where a user inputs a YouTube video URL, and the service outputs a downloadable MP3 file containing only the audio from that video. This allows offline listening without the need for the video component.
The utility of this process stems from the desire to isolate and retain the audio portion of YouTube videos for convenient listening. This is particularly useful for content such as music, podcasts, lectures, and audiobooks found on the platform. The practice evolved with the increasing prevalence of streaming video and the simultaneous need for portable audio files playable on a variety of devices. This service eliminates the need to stream content repeatedly, saving bandwidth and enabling access in areas with limited internet connectivity.
