Frequency range of plot
Hi,
I just purchased SignalScope for the iPhone and have been doing some initial measurements to get a feel for it. Can you tell me why the screen shots on your site show a frequency range from 10 Hz to 20 kHz but I'm only getting a range from 50 Hz to 20 kHz on my display?
I've been using it to get a feel for the frequency response in my acoustically treated listening room using a pink noise test signal (haven't found a white noise signal source yet) and I'm quite impressed by the results, both from the application and from my room. Thanks for a very convenient and useful tool.

On a log frequency scale, the lowest frequency label will depend on the current frequency resolution, which is a function of the number of spectral lines you have selected. Increasing the number of spectral lines will increase the frequency resolution (and decrease the update rate of the spectrum).
You can change the number of spectral lines in the options tab.

Two third-party apps cannot run at the same time on the iPhone.
