So, I got tired of loading up a spectrum analyzer on an oscillator and then trying to estimate aliasing amount from the peaks in the spectrum that moved from high to low when slowly increasing pitch.
I thought, there got to be a better way.
So I made Aliasmeter, it measures aliasing/noise to signal ratio. Its made for plugin devs to test their own modules, for example if not not sure how much difference oversample at x2 vs x4 matters, or if the minBLEP/polyBLEP is working correct. Now you can measure the difference. Please read manual before use.
