Last year, Spotify announced news of a karaoke feature, and this year, they are filing a patent for it. According to Digital Music News, the patent is for a ‘Karaoke Query Processing System‘. Upon the initial announcement of the feature, the popular audio streaming app would allow users to swipe up from their selected song and lyrics would populate the screen. Users would also be able to control the volume while the lyrics showed up on the screen.
“AN ELECTRONIC DEVICE RECEIVES AN AUDIO CLIP AND PERFORMS A MATCHING PROCESS ON THE AUDIO CLIP. THE MATCHING PROCESS INCLUDES COMPARING AT LEAST A PORTION OF THE AUDIO CLIP TO A PLURALITY OF REFERENCE AUDIO TRACKS AND IDENTIFYING, BASED ON THE COMPARING, THE FIRST PORTION OF A PARTICULAR REFERENCE TRACK THAT CORRESPONDS TO THE AUDIO SAMPLE. UPON IDENTIFYING THE MATCHING PORTION, THE ELECTRONIC DEVICE PROVIDES A BACKING TRACK FOR PLAYBACK WHICH CORRESPONDS TO THE PARTICULAR REFERENCE TRACK AND AN INITIAL PLAYBACK POSITION OF THE BACKING TRACK.”
