MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202631020660 A) filed by Jis College Of Engineering, Kalyani, West Bengal, on Feb. 22, for 'automated multi-parameter karaoke track generation and instrumentation re-composition system.'
Inventor(s) include Prof. Bikramjit Sarkar; Kaushik Roy Choudhury; Sumanta Chatterjee; Nilabha Das; Juhi Das; Ipsita Kundu; Ishita Kundu; and Pritam Baidya.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an automated system and method for generating customized karaoke tracks from digital audio files. The system separates vocal and instrumental components of an input audio file using artificial intelligence-based source separation, transposes the instrumental component to a user-selected musical key or scale while preserving tempo and harmonic integrity, and dissects the instrumental component into individual instrument tracks. The instrument tracks are converted into symbolic representations and selectively reconstructed using a user-defined combination of instruments from a predefined library. The reconstructed instrumental component is rendered into a high-fidelity karaoke track, free of original vocals, in standard audio formats such as MP3 or WAV. The invention enables real-time or near real-time production of studio-grade karaoke tracks with flexible scale and instrumentation customization, suitable for both professional and consumer applications."
