DigiGal,
Here are some screenshots of the app displayed on the new 4 inch Retina display. We added the Mic Separation display to the Bombsight view.
I think (hope) people will find the new tools pretty useful. Using capabilities built into the device, we wanted to address the complexity in determining the necessary coverage angle (Performers Angle) and the difficulty in accurately measuring the Mic Angle.
The Performers Angle Viewer is pretty easy to use but really hard to show with a photo. As you rotate the camera, the angle from center stage to stage L and to stage R is displayed at the top.
The Bombsight is a little trickier to use since you want the device flat (bubble level in the middle) as well as having the camera directly over the vertex of the mics and simultaneously rotating the camera so the angle measuring lines align with your mics. It takes a little practice but it isn't a big deal after you've tried it a few times. If someone wants to be anal retentive they can rig up a device mount to hold it in the right spot above the mics, but you can get decent measurements with a steady hand.
The updated Stereo Mic Tools and a less intense update to Mid Side Visualizer are at Apple waiting for review. We're looking forward to hearing what you think when you get a chance to play with them.
