I want to convert db into amplitude ratio.
Here is a little of backstory :
I am a programmer and I have to code an Equalizer; the problem is, I'm new to this DSP world.
I'm using a small documentation that an audio engineer in my company made a while ago and there are stuffs that I don't understand in it. (He's obviously not in the company anymore...)
In his documentation, he writes that the equalization is made step by step with an incrementation of ±0.1 dB.
So here are my questions :
What's the formula to convert dB into a percentage ?
On Wikipedia, there is 10 log10(x), but x is the power ratio, and I don't know how to get that either...
Does processing step by step is the best/only solution ?
Or can I calculate the ratio that I need each time (to limit the number of measures needed) ?
Thanks for you time.
