Slowly getting there… I’m still having problems with the FileGrapherScroll sketch, but I got the plain FileGrapher working with a few small changes:
Sound Level and Heart Rate
Red is the sound level, which I still need to smooth out a bit. Green is my heart rate. Note that the y values are increasing rather than decreasing as they head toward the bottom of the image. This image is taken from a file I recorded while I was waiting for my sweetheart, who had been away all weekend. The sound level increased when he walked through the door and we said hello. As you can see, my heart rate went through the roof, too. Mushy, right?
