 As an evaluation metric, we are using the signal-to-distortion ratio (SDR), which is defined as,

+$SDR_{instr} = 10log_{10}\frac{\sum_n(s_{instr,left\ channel}(n))^2 + \sum_n(s_{instr,right\ channel}(n))^2}{\sum_n(s_{instr,left\ channel}(n) - \hat{s}_{instr,left\ channel}(n))^2 + \sum_n(s_{instr,right\ channel}(n) - \hat{s}_{instr,right\ channel}(n))^2}$

 # Baselines
 
-TODO: To be added
+We use Open-Unmix for the baseline. Specifically, we provide trained checkpoints for the UMXL model. You can use the baseline by switching to the openunmix-baseline branch on this repository. To test the models locally, you need to install `git-lfs`.
