Anyone know of an Oscilloscope app? a nice single scope using the internal soundcard would be cool. I am not sure if the droid has a line level input or not. probably mic only.
I've seen one or two apps that tried to have an oscope-like drawing of the microphone's input. Tricorder recently added the ability.
There's also another program, SpectralView, that draws a nice 2d FFT up to 8 kHz (more bandwidth in paid version)
No line-in to my knowledge, just line-out. You might be able to hack a bluetooth headset into a probe, but you'd still be AC coupled, so kinda useless...
