Passing that flag did nothing noticeable. All I need to do is copy and past into that make parameters text box, correct? Didn't seem like hitting enter did anything.
As far as what I'm doing in initialization, I'm just generating wavetable oscillators, and filling them with float values. In my current project, it's 4 objects, each with 11 float arrays of size 4096. I'm generating the tables based off harmonics per octave, which is where my my use of the sin function comes into play. The fact that it works in a few seconds with sinf_neon and a few minutes with sinf is extremely strange, and its leading me to believe that I have done something stupid, but cannot figure out the issue. My project is not very complex (yet), so I'm not really sure where the mistake is happening.
After doing some testing, I see that the problem is within the object initialization. If I create one object, it takes less time. If I create 4 objects, it takes much more time (as expected). This time difference in unnoticeable using neon, but multiplied while using cmath.
