Intermod is an application that uses Visual Basic with an MSExcel front-end. It calculates possible intermodulation products within wireless Microphone systems. Intermod includes tools to help the audio engineer Drill down the massive amount of data, to a smaller set of most significant results, allowing better selection or elimination of elements in a given system.
Intermod theory
Calculating intermods for a set of numbers is described by the formula:
As you can imagine, large numbers of frequencies or large numbers of Orders produce a very large number of calculations that need to be performed and checked. For instance, checking 24 frequencies to 5th order produces over 2 million results.
