A simple sine wave tone and DTMF tone player.
This application is meant to be used for quick and simple testing. It is good for setting a level, testing a DTMF decoder or other simple tasks that do not require precision testing.
Please keep in mind this application is not generating the tones on the fly and is not attempting to replace more precise tone generating equipment.
