Outlier MLD score with BASOP decoder for McMASA rate switching and rendering to binaural
Basic info
- Float reference:
- Fixed point:
Bug description
Not the most critical issue but there is an outlier MLD score with the provided processing command with combination of float encoder to BASOP decoder. What makes this outlier is that the MLD is 10.7 (compared to full float path) whereas paths including BASOP encoder have MLD of about 7.5. Usually the float to BASOP decoder path has smaller MLD due to having the same bitstream. This could suggest something going wrong.
Plots do not give too much clue either. Below is the time domain plot and maybe the diff spikes are a clue.
