What is wrong with > compile time switches/options? maybe yes; depends on how many resamplers there will be a loadable module interface enforces a stricter and more stable interface, which may be a good thing some refactoring is in place anyway, so depends how far we want to take it > > > > > > Speex has been obsoleted [2] and the resampler seems to had been moved to > > > > > > opus-tools.
