About this app

This app is a fast and helpful tool for calculating stereo microphone setups and checking signal levels in a recording chain. It consists of two modules:

Recording Angle Calculator

Interactive calculation of the stereo recording angle for stereo microphone recordings and standard stereo loudspeaker setup (60°). These parameters can be varied: polar pattern, microphone distance, included angle, desired stereo recording angle and the ratio between time and level differences. The setups for time-of-arrival stereophony (time difference between two spaced microphones), level-difference stereophony (level difference between two angled microphones), and mixed setups are thus visualized. Well known stereo setups like AB, XY, ORTF, and Blumlein are available as presets.

Gain & Level Calculator

The signal levels for the complete recording chain are calculated, from the acoustical source, via microphone and pre-amp up to the input of an A/D-converter. Sound pressure level, microphone sensitivities, pre-amp gain and sensitivity of the A/D-converter are the variable parameters.

Info texts in the app provide detailed explanations of the function, and the technical parameters.

If you have phone with only virtual buttons it does not play well for exiting...

Great app for sound engineers
