I hope you liked my video. I don't like it because it needs improved. I should have removed the pictures from the wall. I will do it again. I know, its off topic, but it is also on topic because members of vortex are prone to do demos. The latest version of android has pause. I could make a video start / stop / pause release. That way you could switch seens. I have found that it is difficult enough do one seen, multiple seens with front and back cameras would be challenging. I have found in the past that such upgrades do not improve sales. My MIDI Staff is not selling. Many have asked for some way to see the notes that they are singing or playing on a string instrument on a musical scale. Frequency meters are available but nothing that transfers frequency to a musical scale. I am thinking about doing this. This would be the most difficult project yet because I will have to read from the microphone into milli second snippets and then extract the frequency from these files with a Fourier transform a zero crossing method. I already have the graphic built in this app. I could reuse this code. The graphic took a while to develop. https://www.amazon.com/Znidarsic-Science-Books-MIDI-Staff/dp/B018BL8B1Y
I not sure if this will be worth the effort. I will save it for the winter when the snow is flying and I am stuck home. There is nothing more that I can do for cold fusion. I am running my helium in my furnace expansion tank experiment this winter. Frank Znidarsic
