기술 miles' tones

A simple, free, open-source application for singers who want to find pitches on their phone they way they would with a pitch pipe.
The interface is plain but straightforward, similar to a piano keyboard layout. Display can be either sharps or flats. The user can select from a variety of tones (sine, square, PWM, &c) and envelopes (organ, clavier, or fade-in/out).
This was a project for a class on Object Oriented design. It's basically a little mini-synthesizer a single oscillator and envelope.
I figured I would put it up for free in the Google play store. Why not? The sound is a bit raw, but it does work. And after all, the price is right. (...for the user. However, note that the developer must pay to offer things for free!) But with the many things being juggled I've been a bit remiss on maintenance.
That may change, as I have been working on a full blown synthesizer called OndeSynth (also on GitHub, see below), which started out loosely based on the current project. However, it's now much more capable that the original "tones" app, and the JAR is only about a half a meg, so my plan is to include the Ondes tone generator in the "pitch pipe." That should result in some better sounds. One might hope!
