If you would like to make accurate sound level measurements with your iPhone, iPad, or Mac, then proper calibration of your microphone sensitivity is an important step to success. With the right equipment, calibrating a microphone can be a very simple process.
» Read moreAs mentioned in a previous post, iOS 16.0 fails to properly identify connected external audio input hardware (the selected input was always reported to be the built-in microphone). This problem, which we reported to and confirmed with Apple, has been addressed in iOS 16.1, which now properly identifies a connected and selected audio input in Faber apps. If you’re currently running SignalScope or SoundMeter apps on iOS 16.0, an upgrade to iOS 16.1 is recommended.
» Read moreMost tools in SignalScope include some kind of plot (graph) with an adjustable scale for viewing time or frequency domain data. Although each plot typically features one or more options for automatic scaling of the data, it is helpful to know that there are multiple ways to adjust the scale manually.
» Read moreIf you regularly connect external devices to your iPhone to work with SignalScope or SoundMeter, you may want to hold off on installing iOS 16.

» Read moreWith version 11.5 of SignalScope X, SignalScope Pro 2020, and SignalScope Advanced 2020, the Data Recorder and Octave Analyzer tools can be started automatically when a user-defined trigger event occurs. The trigger event consists of a single amplitude threshold on a designated trigger channel.
» Read moreWith the release of version 11.4 of SignalScope X, you can more easily generate and analyze signals with DC content, as long as you have compatible hardware with DC-coupled input and/or output channels. The number of audio interfaces with DC-coupled output channels seems to have been growing for some time, although very few interfaces offer DC-coupled inputs.
» Read moreAs requested by our Pro Audio customers, SignalScope X Meter, Octave, FFT, and Spectrogram tools can now optionally display voltage levels in dBu.
» Read moreIf you don’t have a laser tach handy, but you do have an iPhone in your pocket, you can measure the router spindle speed with the FFT analyzer tool in SignalScope X which can ‘listen’ to the router with the iPhone’s built-in microphone.
» Read moreIn order to facilitate impact testing, measurement software generally requires several specific options, including reference input triggering with pre-trigger delay, force windowing for the reference input, exponential windowing for all inputs, and the ability to preview captured impulses and accept or reject the inclusion of the captured data in the final result. In version 11.2, SignalScope X now includes these capabilities within the Dual FFT Analyzer tool.
