My game needs to know when users sing a high note, a low note and when they are silent.
I tried using sliders (with energy level or pitch as background). I can use those to config the threshold and range precisely. But nobody seems to understand that.
Then I tried to make them keep silent, make noise, sing a high and a low note while long pressing the screen by displaying text caption. But people still misuse the config screens all the time.
Anyone have any good idea about this?
