Having trouble running my software on MacOS Mojave or later? After many years of distributing my software for free, Apple's recent software policies have made it difficult or impossible for me to continue. Independent developers like myself are now required to pay Apple each year and have our software approved by Apple, otherwise our apps will be tagged as dangerous or "damaged" and can't be opened. For the foreseeable future I can't invest the time and money to fix these problems, but you may be able to work around it by right-clicking the app and selecting "Open" or using the method described on OSXDaily.

Pitch Playground

A quick and dirty demonstrator for audio interference phenomena.

The five sine-wave oscillators can be tuned independently or linked via arbitrary or preset intervals. The amplitudes can also be independent or linked. A calculator keeps track of the ten possible beat-frequencies that are being generated by the interference between the tones.
