## The effect of thresholds and masking on the audibility of audio produc

Just a very quick reply:

I am under the assumption that you first tried to cancel the non-linearly scaled fundamental frequencies (which doesn't work) and then added the input back to that, for the 3rd_30pct file and very likely similar files that is.

If you add half of sin(x)/2+sin(y)/3 to 17/96*sin(x)+11/72*sin(y) then you will have still changed the amplitude difference between those two tones by ~1 dB. You have changed the amplitude ratio of tones in the input. Also, distortion would go *down *relatively speaking.

Btw, such nonlinear operations will cause a lot of aliasing if you do not oversample.
