Here you can start the full play-by-ear game. It allows to enter notes with the mouse piano, a midi keyboard,
or by micro/headset.
Here you can start the tuning device. It listens at the micro/headset and shows the played notes. This is useful, when you want to check the tuning of your instrument or you want to check, if the micro works at all. As it accesses the microphone, it works only after a security query.
Why is there a security query?
And why is there: "the digital signature could not be verified"?
On the following pages you can learn to play by ear. It works like this:
You make some settings (Level, Key, ...). When you click on "Start" then, the applet plays
some random notes, that you have to repeat. There are different ways to enter notes.
The program checks, if you have played the correct notes.
You can continuously see an evaluation.
Additionally there is a digital tuning device.
When you use the microphone (or a headset) for note entry, this is kind of a security risk. For example, I could record the conversation in your room and send it to me at home via net. For this reason Java insists on the applet being signed and you accepting it.
If I had an official signature, you could read the sentence: "the digital signature could be verified"
or something similar. But such a signature would cost me around $ 250.- per year. And just for this
one sentence I do not spend such an amount of money.
So I only have a Java self-crafted signature.
I assure, that the applet does not do anything that would harm your computer or violate your privacy. In particular it does not access your file system or send sound to anywhere. The sound is only analyzed on your machine to know, which notes were played.
