I found a simple hall effect application. Is that what I could use to control the PC soundcard's stereo output volume via a DIY breath controller to add tremolo and/or volume changes?

Not quite sure how it works. As far I discovered it works with moving a little magnet to the hall effect sensor or visa versa. How do I connect the soundcard's outputs to it? Finally, how to make it work logarithmically?
Since I need only to control the soundcard's stereo output, I'm glad not to bother with MIDI control and that surely makes it less problematic.
