There's also a much more trivial way of drastically reducing the cpu load if
you don't care about quality *that* much : reducing the 'filter-length'
property.

Especially when downscaling the sampling rate the quality difference is barely
noticeable between filter-length=64 (default) and filter-length=16 at a vastly
reduced cpu usage.

Maybe those optimisations could be done with ORC, which would provide
optimisations not only for one platform but for all platforms for which ORC has
a backend (x86, mmx, sseX, arm, neon, ...).
