Hi there, WOS sounds interesting !
We strongly suggest you to establish some kind of collaboration with the open/free project called Oversimple by @unevens:
A library for audio oversampling, which tries to offer a simple api while wrapping HIIR, by Laurent De Soras, for minimum phase antialiasing, and r8brain-free-src, by Aleksey Vaneev, for linear phase antialiasing.
Hope that inspires !
