Here is my use case: I wish to resize a vector before transforming with an FFT. Due to the power of two input size contraints, I need to resize the vector to the next greatest power of two.

Linear resampling

I realize I can perform a direct transform at arbitrary sizes but speed is of critical importance. I have seen mention of ippsResamplePolyphase but this looks like one of the most complex, state-driven IPP functions that likely sacrifices speed for generality.

I welcome any suggestions, thank you.
