As I said, I can't tell the proposed resampler from the "default" one (speexrate) in alsa-plugins by ear, but still want their characteristics to be as similar as possible (up to copying the entire impulse response table) so that this bug has no chance to be reopened by "better" audiophiles. This indeed brings up the question of CPU usage with 3D effects, that's why the quality knob.
OTOH, Windows 2000 and XP already have a resampling quality knob. Does anyone know the characteristics of their resampler or the location of the registry value?
And even alsa-plugins and PulseAudio offer some presets with different quality of resampling.
