New EQ for Wah and more!

[Lastie]

Rather than making a guitar amp, I'll make a Parametric EQ!

Whad do left, right, feed, and pass do?

Here is a parametric EQ, basically you have 3 sliders for frequency, gain (volume) of that soecific frequency, and bandwidth that affects how quickly the rolloff of frequencies around that frequency return to 0. This particular one in the photo also has a frequency graph thing where you can drag around the dots to affect the sliders easier, but thats just an alternative UI for it rather than a seperate feature.

For the frequency slider, it should be logarithmic, so 20hz is the farthest left, 2000hz is the middle, and 20000hz is the farthest right. Since the difference between, say 200hz and 500hz is huge, but the difference between 10200hz and 10500hz is almost impossible to hear, it would make it a lot easier to use.

A 0.01 to 4.00 bandwidth slider would be ideal,no point in going higher or lower. This should be linear slider.

Gain should be from -90 db to +18db, this should be logarithmic. Not sure if the way computers process gain is already logarithmic though. Anyway middle of slider should be 0db. You could add more that +18db but that would be very loud and potentially bad for speakers.

To get a wah effect you could sweep from around 500hz with a narrow bandwidth and lots of gain, to around 2000hz.

You should.. totally become an OS dev

So, trying to find the equation for a "Natural Cubic Spline" rn so I can display the curved EQ. Does anybody know what it is?
