Calculator for Stereo Imaging and Coincident Polar Patterns
As an autonomous recording organist I am interested in microphone setups that are quick to set up and give some flexibility to adjust the stereo image and/or polar patterns in post-processing (compared to arrangements like AB and ORTF, that are fixed). Dealing not just by experimenting but also with the theory, led me develop this calculator and some microphone setups, that might not be so well-known. Also, a number of standard setups are shown.
Simple and well-known examples are MS- and XY-Stereo. Extending MS and combining
more than one MS-Setups leads to Stereo with time-of-arrival imaging and also Surround sound.
You can combine up to microphones. Select the polar pattern, angle and phase of each, and play with its signal strength to see the influence on the resulting pattern.
Example: For MS-Stereo select e.g. “Cardioid” in the first column, “Figure 8” and -90° in the second column. Adjusting the signal strengths gives you the resulting pattern and its on-axis angle. The off-axis will be indicated graphically, too.

For minimalistic 2-microphone-setups take a look at the Stereo Adviser as well.
Show realistic patterns (usually the polar response is frequency dependent).
This calculator is currently able to process coincident and AB-setups only.
