Polar Pattern Creator


A demonstration of how a virtual directional pattern can be created and controlled by the combination of 2 different mics…Or, how to roll-your-own polar patterns. I wrote an article on this for Electronic Musician magazine.

Select the type of audio source to use– Live mic inputs or an interleaved-stereo wave file. In either case, the omni (pressure) element should be in the L channel and the fig8 (gradient) element in the R channel.

Because you probably don’t have one of these files lying around, one is included to demonstrate– A flute/piano duet, recorded on opposite ends of a room with the mic array in the middle (see the picture).

The link downloads a 23 MB Zip file containing the Max patch as an application (Mac OS only), short audio file, and photo of the setup used for the audio file. If you take it for a spin, please leave a comment.

Thanks for your interest…Not sure how the file disappeared, but it’s been restored and worked for me. Please let me know what you think, and if you experience any problems. Enjoy!
