I have a DC motor with an SPI 4000 count encoder attached. This results in a pretty nice sinus signal, and I would like to play it through the audio library.
How do I add the variable as an input?
You would either want to directly set the value of a DC audio object from the encoder, or use the queue object https://www.pjrc.com/teensy/gui/?info=AudioPlayQueue
Audio quality from the DC object will depend on how fast you update the thing and what happens if you change it mid processing interval, suspect getting actual nice tones would require logging values into a buffer and then feeding them into the queue object to allow changes during the audio library interval
