Useful but...

Basic test tone utility app which does what it says, but could be improved by providing basic control options for the pink and brown noise and the frequency sweeps. Such as setting frequency bandpass for pink noise, an option to manually enter & save the start and stop frequencies and sweep time for the frequency sweep would make the app more useful.
