Use a -40dB drop for bsinc12
This improves the transition width at the cost of slightly more audible high-
frequency noise (nothing compared to linear or cubic, but still some). The
previous transition band caused a noticeable loss in higher frequencies, making
lower sample rate sources sound exceptionally dull or muffled.
