Custom audio resampler

Hi all,

I have run some subjective quality evaluation tests on the internal
resampling done in SDL’s audio subsystem. Since there is no filtering
applied after interpolation, there are a lot of artifacts. Rather than
propose that the internal resamplers be improved, as I understand that
this is a quality/speed tradeoff, I would like to ask whether we can
expose the ability to plug in a custom resampler? I see that this is
possible in the internals, but it is not exposed in the API. Is this
something that could potentially be done without too much trouble?

Kind regards,

Philip Bennefall
