  • Decoder (float): d3f01fcf (Thu Apr 24 11:42:19)

Bug description

The castanets test sample rendered lower level for float compared to BASOP for the last two beats. It turns out that BASOP is closer to the input signal, which is why this is labelled a float reference issue.

The input sampled is normalized to -26 LKFS, which leads to clipping. This is not really desirable.
