The process involves extracting the audio track from a YouTube video file and saving it in the MPEG Audio Layer III (MP3) format. This action results in an audio-only file suitable for playback on various devices, such as smartphones, computers, and MP3 players. For example, one might use an online service or software application to obtain an MP3 file from a YouTube music video.
The appeal of this method lies in its ability to create a personal music library from content freely available on YouTube. This facilitates offline listening, bypassing the need for a constant internet connection or a premium subscription to a streaming service. Historically, the practice gained popularity due to the widespread availability of conversion tools and the desire for convenient access to audio content. This also includes archiving music or creating custom playlists.
