Do we really need more than 80dB ultrasound filtering, it will be masked by the
souncard noise anyway, and masked even more by the amplifier noise.
On the other side, i think it's possible a long impulse response may introduce
some audible artifacts and it requires more CPU.
Mixing speed may be important when mixing many buffers e.g. 3D buffers.

It would be possible to add some quality control. We could store the quality
index in some reg key e.g. Software\Wine\DirectSound\ResampleQuality
