The process refers to the action of acquiring audio files, specifically in the MP3 format, from video content hosted on the YouTube platform through the internet. An instance would be using a web-based service to extract the audio track from a music video found on YouTube and saving it as an MP3 file on a personal device.
This practice provides a convenient method for users to listen to audio content from YouTube on devices that may not have consistent internet access or are not conducive to video playback. Historically, this method gained popularity due to bandwidth limitations and the desire to curate personalized audio libraries from online video resources.
