It aims to be a small game for audio-techs that plays a sinus-frequency and displays buttons for the 31 freqs of a normal master eq. Now you have to select the right frequency that is played. Of course reaction-time and error-rate will be evaluated.


I started with a small prototype in pd. The current state is:

  • frequencies are generated at random (from the number of 31 frequencies you want to train for the big graphic equalizers)
  • searching the right frequency with buttons works, if you find the right one the next freq is generated, clicking the wrong one increments an error-variable (with abs( freq - guess ))

I know I did this in puredata. But I don't know whether I still have the file...
