Other than her discovery suggesting that the vocal degree within the function might be adjustable, particulars in regards to the but to be launched (or introduced) function had been fairly slim.

However right this moment, we will shed extra mild on what Spotify is perhaps constructing.

In line with a patent granted to Spotify within the US this month – and leaked to MBW by an insider – Daniel Ek’s firm has been focusing not less than a few of its consideration on a brand new function that enables customers to “overlay a music observe with their very own vocals”.

The patent, which you’ll learn in full right here, was filed in December 2015 and granted on September 8 2020.

It provides: “Customers could, for instance, want to overlay a music observe with their very own vocals by singing right into a microphone because the music performs.”

The patent explains that typical karaoke techniques “include a wired microphone bodily plugged into a tool that solely performs regionally saved content material”.

“Consequently,” the patent provides, “typical techniques considerably encumber the flexibility of customers to pick and management media content material for playback, and to simply present their vocals for overlaying with media content material”.

Spotify suggests, due to this fact, that “there’s a want for units, techniques, and strategies for overlaying audio information for person vocals and media content material acquired from distinct units and techniques”.

This sounds very very like a web-based karaoke function, no?


The patent goes on to elucidate that the person vocals might be “captured utilizing a microphone of a shopper gadget” which can then “be transmitted to a media presentation system, whereas corresponding media content material, corresponding to a music observe, is transmitted to the media presentation system from a distant server distinct from the shopper gadget”.

“Customers are due to this fact in a position to extra effectively, successfully, and securely overlay and play again audio information.”



Maybe essentially the most attention-grabbing a part of Spotify’s patent is its reference to “auto-tuning the vocals”.

The patent reads that “in some implementations, [Spotify’s] media presentation system auto-tunes the vocals utilizing information acquired from the distant server indicating pitch, beat, and/or chords for the primary media merchandise (e.g., pitch information saved in metadata database).

“The media presentation system overlays the auto-tuned vocals with the primary media merchandise to generate the composite information stream.

It additionally provides that “in some implementations, the media presentation system modulates the vocals to provide a particular sound impact (e.g., a robotic voice or vocoder impact) and overlays the modulated vocals with the primary media merchandise to generate the composite information stream”.


As famous final week, Tencent Music Leisure (TME’s) WeSing app serves as a first-rate instance of what will be achieved within the app-based karaoke enterprise, with Spotify’s entrance into this area making a number of sense.
