New member here, so big wave to you all from Melbourne, Australia - thanks for having me.
Now, I need to sound an idea and get some advice/direction from you guys. Using lemur and an iPad, I'm building a production / DJ toolset which I hope to use to help me during production of music stems and 'play' said music in a 'live' capacity.
I've been working on a triangular fader between 3 audio sources - effectively it's an equilateral triangle on my screen, and my finger position (the cursor if you will) determines the distance from the 3 verticies of the triangle and from a range of 100 (on the vertex of that channel) to 0 - I've got a linear crossfader of sorts which provides the volume level of each of my 3 channels nicely....
However, as we know - sound doesn't work like that and I won't get a nice constant-power curve as is expected to be used when fading from a > b, for example on a DJ mixer.
Through some investigation online, I've got the trigonometric function which mimics how most constant-power crossfaders work between 2 channels (y=cos((pi*x)/2) if you wanted to know) - but how would I go about introducing a 3rd sound source into this....
Do any of you have any knowledge on managing more than 2 audio sources taking constant power into consideration? Would I simply just apply the same function to the 3rd audio source as I've done with the first two?
Cheers for any help guys!
