Just ordered my DSO Nano V2 and I am looking forward to using it. Since the device is firmware enabled, I suggest that someone who knows how to program it come up with some much needed audio tools:
Audio RTA 1/3, 1/6 and 1/12 octave, A, C and flat weighted
SPL meter, A, C and flat weighted
SPL graph
FFT
ETC
Impulse response
speaker polarity
RT60
I would like to help if anyone is interested in doing this project.
