Prior to finding this app about 2 years ago. I almost considered keeping a protractor in my gig bag. This app in utterly indispensable and is worth far more than the pennies I paid for it. I almost feel like I’m cheating when I’m using this app to set initial microphone angles. Bombsight let’s confidently set your microphone angles, and “Performer’s Angle” overlays an angle meter on your camera to survey the performers and be sure they’re within your set recording angle. Especially useful for live concert location recording where I’m limited to where I can put my microphone stands and I have limited time to “play around” with my near coincident pair.

Make no mistake, the app doesn’t make great recording for you, it outfits you with simple tools that help your get your results faster.

Fantastic App

This is a really fantastic app for audio engineers. It's got a ton of great tools for setting up various stereo miking configurations, especially coincident and near-coincident pairs. The bombsight feature is excellent for getting your angles just right, and the Recording Angle and Recording Angle _75% markings have been a huge help for me when it comes to figuring out what technique to use for certain situations, and where to place various sources in relation to the mics to get the most accurate stereo imaging. Well worth the price.

Thank you!

Thanks for the update! When the new IOS messed up the app I had to carry around an extra older phone for this app. As a classical location recordist this is a terrific reference. Beats just carrying around the Williams mic charts.
