Resampling MAY involve interpolation, to enhance the subjective quality of the output. > If you haven't noticed, this is just upsampling/downsampling without lowpass. > And that is not resampling in any way. No matter how many times you repeat it, saying that changing the sample rate is not resampling will not make it true. > That is just your opinion now, you need to provide technical terms > to support your statements. I have given technical considerations: we have automatic sample rate negotiation. These filter would not fit with it. What have you provided besides your opinion and links to generic considerations that do not substantiate your views? > Another option to aresample filter would just confuse users. Less so than yet another pair of filters that do almost exactly the same thing as others. Regards, -- Nicolas George
