TestTone is a very simple test signal generator plugin that lets you quickly send out the signal you need — sine waves and pink noise — with adjustable frequency and level. It is handy for setting up gear, calibrating monitoring systems, and various audio checks.
Available in VST3, AU, AAX, LV2 and CLAP formats for macOS, Windows and Linux. Free and open source (AGPLv3 License).
I have created a demo site as a web application that runs in your browser, so please feel free to try it out.
