SignalScope update supports audio mixing on iOS



SignalScope Pro 6.1 and SignalScope 7.1 have been released for sale on the App Store with some important enhancements, including the ability to mix audio output with other apps. Audio mixing means that it is possible to play music from the Music app while performing signal analysis with SignalScope or SignalScope Pro. It is also possible to mix the output of the signal generator* with the audio output from another app.

The SignalScope apps include other important enhancements:

  • The FFT analyzer tool now supports frequency resolution as fine as 0.1 Hz for audio input signals.
  • When working with an iPhone or iPad that has multiple built-in microphones, the unique name of the selected microphone is displayed (e.g. “Bottom Microphone” or “Right
  • When analyzing two input channels in the Octave tool, both spectra are displayed in a single line plot.

Easy calibrated vibration measurements on Mac or iOS

digiducer_04_CE_mediumAlthough Faber Mac and iOS apps have offered excellent sound and vibration analysis tools from the start, the introduction of the Digiducer 333D01 USB Digital Accelerometer makes vibration measurement easier and more portable. When the 333D01 is connected to a Mac, iPhone, or iPad, it will be immediately recognized by our apps and ready for calibrated measurements.

For example, SignalScope Pro will recognize the connected 333D01 as an accelerometer and set the measurement units accordingly. SignalScope Pro will also automatically read calibration information from the 333D01 and establish the appropriate sensitivity so calibrated measurements can be made immediately. This works with both the Mac and iOS versions of SignalScope Pro.


The 333D01 communicates with Mac OS or iOS via the standard USB Audio Class driver. Connecting to a Mac is as simple as plugging the 333D01’s cable into an available USB port. For iOS, Apple’s Lightning to USB Camera Adapter is required.* When connecting to iOS, no additional power source is required, which makes Faber apps and the 333D01 part of an ultraportable vibration measurement system.


Auto-calibrated measurements with the 333D01 are supported in Electroacoustics Toolbox, SignalScope and SignalScope Pro for Mac, and in IOScopeSignalScope and SignalScope Pro for iOS.

SignalSuite for iOS now sports a fresh UI and support for larger iPhone screens

SignalSuiteAppIcon120Version 1.5 of SignalSuite, the original stereo audio signal generator for iPhone, finally supports larger iPhone screens, including those of the new iPhone 6S and 6S Plus, with a fresh new look. Functionally, the new version of SignalSuite is equivalent to previous releases, although it is now possible to manually select from a list of available audio output routes (e.g. the iPhone speaker or an Apple TV on the local network). The user interface elements have been updated to be consistent with the changes made to the appearance of iOS since version 7.

SoundMeter now offers Octave data logging on iPhone and iPad

For some time, SoundMeter has offered an optional in-app upgrade that would allow users to log sound level and noise dose measurements for up to two weeks. Version 8.1 adds an upgrade to allow whole and 1/3 octave sound levels to be logged for similar durations. The Octave Data Logging Upgrade will be made available within SoundMeter to users who have already purchased the Octave Analyzer Upgrade.


When Octave data logging is enabled, logged levels are displayed in a 2D color surface plot below the standard Octave spectrum graph. The color scale is defined by the vertical scale of the spectrum graph. A data cursor may be placed within the log plot to identify specific levels associated with date,  time, and frequency band.

Octave data can be logged as often as every 0.1 seconds for up to 1 hour, every second for up to 10 hours, or every 10 seconds for up to two weeks. Larger intervals can also be specified in each case.

When data logging is enabled, logged levels will also be included when saving data to a CSV, TXT, or MAT
file. (Saving data in SoundMeter requires the Data Acquisition Upgrade, sold separately.)

SoundMeter Pro includes all the functionality of SoundMeter plus that of SoundMeter’s in-app upgrades. Current SoundMeter Pro users get the additional Octave data logging functionality for free.
