btw, you probably (or possibly) don't want actual logarithmic sliders. the faders on any sane mixing surface and both logarithmic and nonlinear (i.e. more precision near 0dB)
and you would do the non-linear mapping somewhere other than in the view code? Any slider will do if it generates a linear floatValue from 0..1 and then just map that range in a controller class to whatever range you need to send to the AU. That's how I'm doing it at least..
-(IBAction)volume:(id)sender { float map_volume = function_to_map_linear_to_fader_value([sender floatValue]); // send map_volume to AU }
that is what i would do, too; everything from a GUI goes to 0. 1. and then you can map or distort stuff elsewhere.
i have about 50 different curves based on the usual mathematical formulas such as log, cos, hyperbolic tangens, bipolar expressions (for things like panning), leave alone expressions for a certain purpose.
usually one line of code and you can type it faster than downloading a third party class. :D |
