The phrase refers to the process of obtaining the audio component of video content hosted on YouTube, specifically for use on Apple’s iPhone devices. This involves extracting the sound track from a YouTube video and saving it as an audio file, which can then be stored and played on an iPhone. Common file formats for such extractions include MP3 and AAC. For instance, a user might want to isolate the music from a concert recording on YouTube and listen to it on their iPhone without viewing the video.
This ability offers several advantages. It allows for offline listening, conserving mobile data. It’s useful for accessing audio-only content when visual attention is not possible, such as during commutes or workouts. Historically, dedicated apps and websites have emerged to facilitate this process, reflecting a user demand for flexible media consumption. However, it is important to acknowledge the potential copyright implications and terms of service violations when engaging in such activity.
