8bit Converter
In this website, we present our example clips, for those who are interested in the result of our works.
For more details, please refer to our paper here,
And you can find our codes here. Note that the codes we release is a reimplemented version of our system in python, which may generate a slightly different result, and we are still working on it to make the documentation complete.
Click the sidebar on the left can help you move to a specific example.

All clips used in this website are for academic purpose only.
Example 1: Adele - someone like you
Original clips
Method 1 : Directly use NMF
Method 2 : Separate first, and directly use NMF to voice and background
Method 3 : separate, apply pYin and background constraint, synthesize in frequency domain
Method 4 : separate, apply background constraint, apply Let It Bee
Method 5 : Proposed method (Without NMF Constraint)
Method 6 : Proposed method (With NMF Constraint)
Example 2: John Legend - All of Me
Original clips
Method 1 : Directly use NMF
Method 2 : Separate first, and directly use NMF to voice and background
Method 3 : separate, apply pYin and background constraint, synthesize in frequency domain
Method 4 : separate, apply background constraint, apply Let It Bee
Method 5 : Proposed method (Without NMF Constraint)
Method 6 : Proposed method (With NMF Constraint)
Example 3: Christina Perri - Jar of Hearts
Original clips
Method 1 : Directly use NMF

Brief Explanation
In this section, we briefly show some image/spectrum to help understand our works more clearly.
