Comment (by Kamedo2):
v5 vbr is still quite worse than the abr. I feel that whenever tonal
sounds are there, the frequency bin around the tone degrades. Tones are
poorer at hiding other sounds than the noise, that's why harpsichords
remains to be one of the most critical and hardest instruments to code.
