How does the tuning applet work?




On the left side you see, what the applet should look like, when no note is being played, on the right side, when a note is played.
In the upper green field (1) you see the spectrum of the current note. When you are currently playing, there should be only a few regular peaks visible. Additionally the level bar (2) should be clearly visible.
If there is nothing being played, the level bar should be very small, and in the spectrum field there should a uniform noise.
In the yellow field (3) in the bottom you see the illustration of the found note. The vertical lines directly beneath the note names show the calculated note frequencies. The vertical lines between show the boundaries between the notes.
The black rectangle under the note names shows the found note. The width of the rectangle shows the exactness of the calculation.
In our example you can see, that if the note would only be a bit lower, it might be taken for a f-sharp.
Normally there is no note shown, when nothing is played. But it is possible, that a random note is recognized. But such a random note will vanish very fast.

Then you have a problem. Try
- to bring micro and instrument closer together
- to increase the input level,
Input level setting is done differently in each operating system version.

Then we both have a problem. Try
- if playing louder or less loud makes it better.
Currently the frequency of the standard pitch (=440 Hz) and the equal temperament tuning cannot be changed. This comes from the fact, that midi is used for sound output.
