-That noise board is based on a design made by Urs Gaudenz from [[https://​www.mechatronicart.ch/​|Schweizer Gesellschaft Für Mechatronische Kunst]] - thanks for that!\\ 
-I added the voltage controll and some extra funcions, like the noise on/off the boost and the mute function. 
  
-The Electric Intonarumori has an audio an an control voltage input, while building the board one has to choose between bus 1 and bus 2 for the audio input and the other bus for the control input.+The core of that noise board is the digital delay chip [[http://​www.princeton.com.tw/​Portals/​0/​Product/​PT2399_1.pdf|PT2399]]. It has some OpAmps build in to filter ​the sound and do the echo. In this application everything that helps to get rid of the noise of the chip itself was avoided, that leads into a self sustainable noise source.\\
  
-The board is named after the intsrument ​"​Intonarumori"​ of the Italian Futurist, painter, composer and the author of the manifesto The Art of Noises, [[https://​en.wikipedia.org/​wiki/​Luigi_Russolo|Luigi Russolo]].+The board is based on a design of the [[https://​github.com/​GaudiLabs/​ChaosLooper|Chaos Looper]] by [[http://​www.gaudi.ch/​GaudiLabs/?​page_id=50|Urs Gaudenz]] from Gaudi Labs and from the [[https://​www.mechatronicart.ch/​|Schweizer Gesellschaft Für Mechatronische Kunst]] - thanks for that!\\ 
 +I added the voltage control of the delay and some extra functions, like the noise on/off, the boost and the mute function to the circuit.\\ 
 + 
 +The "​echo"​ could be changed with a potentiometer,​ the "​delay"​ with CV (0 to 5V) or with a potentiometer. An other Low Pass filter could be changed with the third potentiometer.\\

 +The Electric Intonarumori has an audio and an control voltage input, while building the board one has to choose between bus 1 and bus 2 for the audio input and one has to use the other bus for the control input.\\

 +The board is an homage and is named after the instrument ​"​Intonarumori"​ of the Italian Futurist, painter, composer and the author of the manifesto The Art of Noises, [[https://​en.wikipedia.org/​wiki/​Luigi_Russolo|Luigi Russolo]].\\
