Vern,
FPPO implies FFT-based fractional octave band analysis, which we have no plans to develop. However, we do have a product in the works that will perform whole and third-octave band analysis with true digital Butterworth bandpass filters.
Also, in the current versions of the iPhone OS, you cannot play files from the iPod while SignalScope is running. However, the new product just mentioned will include a built-in pink noise generator.
