Faber Mac apps now support USB measurement mics and accelerometer

Versions 3.8 of SignalScope, SignalScope Pro, and Electroacoustics Toolbox for Mac OS now offer built-in support for USB measurement microphones from miniDSP and Dayton Audio as well as the model 333D01 USB accelerometer from Digiducer.

Each app directly supports the miniDSP UMIK-1 and Dayton UMM-6 USB measurement microphones. Sensitivity calibration data for these mics can be downloaded automatically, just by entering the mic’s serial number. Making calibrated sound level measurements is as easy as plugging in the UMIK-1 or UMM-6, typing in its serial number, and getting started with the analysis tool of your choice (the serial number only needs to be entered once, after which the app will remember the microphone sensitivity). An internet connection is required to download sensitivity information for the microphone.

Each of these apps also directly supports the Digiducer 333D01 USB digital accelerometer, and can automatically load serial number and sensitivity calibration information directly from the device. Making calibrated acceleration measurements is as easy as plugging in the 333D01 and getting started with the analysis tool of your choice.

Various bugs and potential instabilities in each app have been corrected.

These apps all require Mac OS version 10.7 or later.

SoundMeter Pro adds NC, RNC, NR reference curves and Octave data overlays

SoundMeter Pro 3 now offers the option to overlay noise criteria (NC), room noise criteria (RNC), or noise rating (NR) references curves over the live Octave analyzer bar graph. When NC or NR references curves are visible, SoundMeter Pro also calculates the NC or NR value, respectively. Speech interference level (SIL) is also calculated.

As in the recent update to SignalScope Pro, SoundMeter Pro’s Octave analyzer tool now offers the option to load whole or 1/3-octave spectrum data from exported Octave data files. Up to six sound spectrum curves can be overlaid on the live bar graph. It is possible to select the individual channels from which to load data when multiple channels of data exist within a single file. Also of note is the ability to overlay 1/3-octave data on a whole-octave bar graph and vice versa.

SoundMeter Pro 3 also features the following improvements:

  • The Octave tool now calculates Lp, Leq, and Lx values, regardless of which is currently being displayed.
  • The Octave tool calculates the noise criterion (NC) and speech interference level (SIL) as defined in ANSI S12.2-2008, as well as the noise rating (NR) level.
  • SoundMeter Pro 3 employs a new plotting framework for real-time data graphs and high resolution image export.
  • GPS coordinates, altitude, and accuracy may now optionally be saved with Octave analyzer data. Retrieving location information now works on iOS 8 for the Meter and Dosimeter tools, which can also export more detailed location information.
  • When viewing details for data files saved within the app, the Open In button now works properly on both iOS 7 and iOS 8. Depending on the file type and the apps installed and/or configured on your iOS device, options may be presented for emailing, previewing, printing or copying the file, in addition to opening the file in another app.

SoundMeter 7 offers the same enhancements as SoundMeter Pro 3, although some of the new features require upgrades which are available in SoundMeter via in-app purchase. These upgrades include the Octave Analyzer RTA Tool, Percentile-Exceeded Sound Levels, and Data Acquisition Support.

SignalScope Pro 5 adds FFT and Octave data overlays, new hardware support

SignalScope Pro 5.0 and SignalScope 6.0*, both now available for download on the App Store, add support for up to 7 FFT spectrum curves to be loaded from existing data files (CSV, MAT, or tab-delimited text files previously saved from the FFT analyzer tool). Live FFT data can be overlaid on these curves. When loaded data files include multiple channels of FFT data, one or more of those channels can be selected for display in the current FFT plot. The addition of controls for adjusting the line thickness and opacity of loaded data makes it easy to visually distinguish between live and static FFT data. The FFT analyzer also now supports fractional-octave band smoothing of curves displayed in the plot. (It is important to note this is simply smoothing of the FFT curve—it does not simulate the behavior of true fractional octave band filtering, such as that offered by the Octave analyzer tool, which is included in SignalScope Pro.)

The Octave analyzer tool** also now offers the option to load whole or 1/3-octave spectrum data from data files. Up to six curves can be overlaid on the live bar graph. Again, it is possible to select the individual channels from which to load data when multiple channels of data exist within a single file.

Another significant addition to SignalScope and SignalScope Pro is direct support for iTestMic and iAudioInterface2 hardware from Studio Six Digital, as well as the Dayton UMM-6 USB measurement microphone. The new hardware support is consistent with the additions made to SoundMeter Pro 2.3.

Also new in SignalScope Pro:

  • SignalScope Pro 5 employs a new plotting framework for real-time data graphs and high resolution image export.
  • The black color scheme now uses black status bar, toolbar, and tab bar backgrounds.
  • Support for drawing directly to an external screen (from iPad) has been removed in favor of screen mirroring, which is handled by iOS.
  • Audio hardware input and output options are now presented from a separate toolbar button, which looks like a microphone, on iPad, iPhone 6 and iPhone 6 Plus.
  • It is possible to adjust the line thickness of live and loaded frequency response data. The opacity of loaded data can also be adjusted in order to make the live data stand out in the graph.
  • The oscilloscope time scale can now be set from the oscilloscope options menu.
  • Saving an audio file no longer causes a crash when working with large oscilloscope time scales.

SoundMeter adds support for iTestMic and iAudioInterface2

SoundMeter 6.3 and SoundMeter Pro 2.3 now officially support the iTestMic and iAudioInterface2 from Studio Six Digital.

With iTestMic, microphone sensitivity will be automatically loaded from calibration information stored in the iTestMic’s internal memory. This calibration information may have been set at the factory, or it may have been set from within an app, such as SoundMeter. In SoundMeter, it is possible to perform a sensitivity calibration without overwriting the calibration values stored in the iTestMic. SoundMeter can also store that information in the iTestMic for calibrated measurements in other apps that support the iTestMic. SoundMeter also supports selecting iTestMic’s high and low input ranges.

Note: There is currently a bug that sometimes invalidates the calibration information stored within the iTestMic for the High mic input range. This bug affects use of the iTestMic with Studio Six Digital’s own apps, as well.

With iAudioInterface2, SoundMeter can select between mic and line input types, mic and line input gain ranges, and manual volume control options. The volume control knob of the iAudioInterface2 can be assigned to the input gain or the output gain, or it can be disabled entirely to avoid accidentally invalidating the current sensitivity calibration. Also from within the app, Phantom power and digital audio output may each be enabled or disabled. SoundMeter remembers each of these settings for the next time you connect iAudioInterface2 or relaunch the app.

The new SoundMeter apps also support the Dayton UMM-6 USB measurement microphone. When the UMM-6 is detected, the user will be prompted to enter its serial number, which is typically printed on a label on the UMM-6. If a valid serial number is entered, SoundMeter will automatically download a calibration file from Dayton’s website and set the microphone sensitivity based on the information in the file.

Note: The Dayton UMM-6 must be connected to your iOS device via Apple’s USB camera adapter (either for Lightning or 30-pin dock connector, depending on your device). Sometimes the UMM-6 shows up in iOS as USB PnP Sound Device. If that happens, unplugging the UMM-6 and plugging it back in will generally solve the problem (it may take 2 or 3 tries). When properly connected, “UMM-6″ will appear as the input device name in SoundMeter’s toolbar (at the top of the screen).
