Short Description

In this project we want to apply single channel source separation (SCSS) techniques to the problem of separating musical instrument sources from a recorded piece of music. For this task the factorial max-Vector Quantization (max-VQ) and the factorial Sparse Coder (SC) models should be used, which have been successfully applied to human speech.

Your Tasks

• Getting an overview of SCSS, especially with factorial max-VQ and factorial SC
• Apply factorial max-VQ and factorial SC to synthetic music
• Identify specific challenges which occur in connection with music
• Possibly modify the SCSS systems
• Possibly apply SCSS systems to real-world music
• Write a report (around 10 pages)

Your Profile/Requirements

This project is suited for Master students in Telematics, Electrical Engineering, Audio Engineering, Computer Science and Software Development.
