Now put some headphones on the teensy headphone connector and hopefully listen to some interesting piezo disc microphonic sounds (this is where the word micro-phone really comes from, it's analogous to microscope, actually). | Now put some headphones on the teensy headphone connector and hopefully listen to some interesting piezo disc microphonic sounds (this is where the word micro-phone really comes from, it's analogous to microscope, actually). | ||

If you were successful with setting up the teensy and piezo microphone, you can make a step further and learn how to wrestle with audio data directly on the teensy! | If you were successful with setting up the teensy and piezo microphone, you can make a step further and learn how to wrestle with audio data directly on the teensy! | ||
With the help of the [https://www.pjrc.com/teensy/td_libs_AudioNewObjects.html teensy documentation] and my example file you should be able to grasp how this works. Basically you write your own teensy audio object by including a C++ class that is structures as documented in the link above. This class will receive a pointer from to the audio input stream coming from the piezo and can do some work on it. | With the help of the [https://www.pjrc.com/teensy/td_libs_AudioNewObjects.html teensy documentation] and my example file you should be able to grasp how this works.
