Spotify patent filing signals new karaoke feature – EDM.com
While digital streaming platforms have given us music to sing back to, it’s not often that technology sings back. That could change with a recently filed patent by Spotify for a “karaoke query processing system”.
The news follows a discovery in September by reverse engineer Jane Manchun Wong, who found a new feature built into the app that would allow users to adjust the vocal levels of songs. Coupled with this patent application, it appears Spotify is seriously considering expanding its reach to karaoke, although the company has not publicly discussed its plans for the technology.
According to the patent application filed on June 24, this system is able to match audio clips of songs with their instrumental versions in order to play a “backing track”, Digital Music News reports.
“In some embodiments, a user begins to sing an a cappella song in the presence of a karaoke system as described herein,” the patent details. “The karaoke system determines what the user is singing and starts playing an instrumental version of the determined song. In some embodiments, the karaoke system plays the instrumental version using the key and tempo at which the user is singing. .
Additionally, the “Karaoke Query Processing System” has capabilities similar to Snapchat’s partnership with Shazam, which identifies songs played near a user’s phone.
The Spotify patent reads: “There is a need for a karaoke system capable of determining the song the user wants for a karaoke performance, even if the user cannot remember the name of the song. or any other attribute of the song except the song melody … The pairing process includes comparing at least a portion of the audio clip to a plurality of reference audio tracks and identifying, based on the comparison, the first part of a particular reference track that matches the audio sample. “
