Faber Acoustical Releases SignalScope X for iOS as a Free Download

Faber Acoustical’s SignalScope X brings powerful new tools for dynamic signal analysis and data acquisition to iOS and replaces all the functionality currently found in SignalScope Pro, SignalSuite, IOScope, and RoomScope with subscription-based tool sets. For the first time ever in an iOS app from Faber Acoustical, SignalScope X may be downloaded for free. The user can then start a 7-day free trial of the Pro Tool Set Subscription. Without a subscription, the user is free to continue to use SignalScope X’s multi-channel Oscilloscope tool. SignalScope X is available for download on the App Store, now.

The original SignalScope and SignalSuite for iPhone were available for download on the opening day of the iPhone App Store. Now, after nearly 10 years of iOS development, SignalScope X offers a clearer expression of Faber’s vision for the future of acoustics-related signal analysis, data acquisition, and measurement on mobile devices.

The most powerful addition to SignalScope X is the new MultiTool. SignalScope X’s MultiTool acts as a project manager and host for the other tools in SignalScope X. On iPhone, up to 2 other tools (subtools) may be added to the MultiTool at one time. iPad models support up to 4 subtools, except for iPad Pro models with 10.5-inch or larger displays, which support up to 6. Besides the obvious benefit of being able to see and interact with multiple subtools, simultaneously, the MultiTool can save its current subtool configuration under a user-defined name. Any of the saved configurations can then be selected for immediate application in the MultiTool. This allows for different configurations to be saved for different projects or jobs. For example, one configuration might include an Oscope and FFT Analyzer and another might include an Octave Analyzer and a Data Recorder. On iPad, one configuration might include all 4. Even when using just a single subtool, the MultiTool allows multiple configurations of that tool (e.g. a unique configuration of the Dual FFT Analyzer for each of several different measurement types) to be saved and recalled at will.

SignalScope X’s new Data Recorder tool supports real-time continuous streaming of up to 8 channels to an audio file. Along with the audio file, SignalScope X can save an “info” file, which contains metadata including date, time, location (if enabled), input channel details, and sensitivity calibration information. This metadata will also be embedded within the audio file, itself.

The new real-time XY Plotter allows the user to immediately visualize time, frequency, and amplitude relationships between two signals, or even create visually appealing images such as Lissajous curves.

Other significant features new to SignalScope X include optional background operation, independent/simultaneous operation of all tools, and independent input/output channel selection in each tool. It is also now possible to directly analyze the output of the signal generator in any of the real-time analysis tools. SignalScope X also makes it much easier to move data files in and out of the app via Files (iCloud Drive), Dropbox, or other apps on a user’s device that can load or export compatible files.

SignalScope X offers in-app subscriptions for Basic, Advanced, and Pro tool sets that can automatically renew at monthly or annual intervals. Subscriptions give users access to updates, new features, and new tools within the subscribed tool set. Subscriptions also cover ongoing hardware support, such as periodically updated nominal microphone sensitivities for built-in microphones on Apple devices, updated nominal voltage sensitivities for select audio input devices, and automatic calibration for audio input devices that include built-in sensitivity information.

The Basic Tool Set includes the Oscope, FFT Analyzer, 2D Real-time Spectrogram, and XY Plotter tools.

The Advanced Tool Set includes the basic tools as well as the 3D Real-time Spectrogram, Octave Analyzer, Level Meter, Data Recorder, and Stereo Signal Generator tools.

The Pro Tool Set includes the basic and advanced tools, plus the Dual-channel System Analyzer (Dual FFT), Room Acoustics Analyzer, and MultiTool.

The existing SignalScope, SignalScope Pro, SignalSuite, IOScope, and RoomScope apps will receive maintenance updates and remain available for sale on the App Store for a limited time for the benefit of those who need access to their respective tools on iOS 8 and 9.

SignalScope X requires iOS 10 or 11 and is designed to take full advantage of the iPhone X’s 5.8” screen.

Press Release

An update regarding the iPad microphone with iOS 9.3+

The Faber app updates released this week address the issue with the built-in iPad microphone input gain. In short, with the release of iOS 9.3.1, Apple chose to change the input gain range for the built-in microphone on iPad, which meant that apps such as SoundMeter needed to either adjust input gain or input sensitivity in order to continue to allow for reasonably accurate sound level measurements. Unfortunately, iOS versions 9.3.1 through 9.3.4 contain a bug that causes the previous input gain range to be applied after a microphone is connected to the headset jack and then removed.

The following Faber apps have been updated with a built-in workaround to properly apply the appropriate input gain on each version of iOS:

Each app has also been updated to support iOS 10 when it is released later this year.

SoundMeter 8.3 offers more powerful data logging

SoundMeter 8.3 and SoundMeter Pro 4.3 can now log sound levels at user-defined intervals for an arbitrarily long period of time. Each includes a new option to automatically export logged measurement data when the measurement duration is reached. If Auto Stop is disabled, SoundMeter will continue to save the current logged data to a new data file each time the duration is reached. This new Auto Save option has been added to both the Meter and Octave tools.

Data logs can be automatically saved to CSV, TXT, or MAT files.

MeterLogOptions Screen Shot 2016-02-24 at 11.08.26 AM

Also new in SoundMeter:

  • When logging, Leq, Lp_max, and peak sound levels can be reset each time they are logged. With this option, it is possible to log a short Leq of 0.1 seconds for up to 8 hours. With the new Auto Save feature, the logging can be extended indefinitely.
  • When logging Lx values in the Meter tool, the user-defined percentile value will be fixed at the time logging starts. It is still possible to view different user-defined percentile values in the live meter display while the fixed percentile values are being logged.
  • A bug has been fixed which could cause errors in the Octave data when logging was enabled.
  • The formatting of the HTTP file server pages has been improved.
  • Audio input management has been improved to avoid the potential for transient noise from the hardware when a new measurement is started.
  • SoundMeter Pro uses much less memory when exporting data logs to CSV and TXT files.
  • The Octave log surface plot uses much less memory when viewing large data sets.
  • Other cosmetic enhancements and stability improvements.

In SoundMeter, the new features will require the purchase of one or more upgrades, which are available via in-app purchase. They are included in SoundMeter Pro.

SoundMeter 8.3 and SoundMeter Pro 4.3 are now available for download on the App Store.

Electroacoustics Toolbox updated to 3.8.3

Electroacoustic’s Toolbox 3.8.3 can now be downloaded from the Mac App Store and from FaberAcoustical.com.

New in version 3.8.3:

  • An issue with channel sensitivity adjustments in the Meter Bridge and Sound Level Meter tools has been addressed.
  • When loading Room Analyzer tools from a project file, if a permissions error occurs for an audio file being used for analysis, an Open dialog will be presented with the file in question selected. Once the file is then manually loaded via the dialog, the permissions will be properly set for the next time the project is loaded. This is an issue with sandboxed copies of Electroacoustics Toolbox downloaded from the Mac App Store.
  • The Room Analyzer tool’s plotting is more reliable when loading the tool from a project file on recent versions of Mac OS X.

SignalScope Pro for Mac has also been updated with the same improvement to the Meter Bridge and Level Meter tools.

SoundMeter updated for iPhone 6S and iOS 9

SoundMeterProIcon76@2xSoundMeter 8.2 and SoundMeter Pro 4.2 are now available for download on the App Store. Each new version includes proper handling of the built-in microphone on iPhone 6S and iPhone 6S Plus devices and minor changes in iOS 9.

Unfortunately, the new iPhones do not support analog input gain selection for the built-in microphones as previous iPhone models did. The fixed input gain of the iPhone 6S/Plus matches the “Mid” input gain setting in the iPhone 5C, 5S, and 6 models. This means that the peak sound level that can be measured using the built-in microphone of the new iPhones is nominally 116.5 dB. Previous iPhones, on their lowest input gain setting, could measure nominal peak levels of 136 dB.Screen Shot 2015-10-20 at 2.56.19 PM

The SoundMeter apps now allow mixing audio with other apps. This means that it is possible to play music from the Music app while performing measurements with SoundMeter or SoundMeter Pro. It is also possible to mix the output of the signal generator with the audio output from another app.

Also new in each app, when using 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 Microphone”).

SignalScope update supports audio mixing on iOS

SignalScopeIcon60@2x

 

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
    Microphone”).
  • When analyzing two input channels in the Octave tool, both spectra are displayed in a single line plot.

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.

OctaveSurf

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.

Real-time 3D Spectrogram now available in SignalScope for iOS

Faber Acoustical is pleased to announce that a live Spectrogram tool is now available for purchase within SignalScope and SignalScope Pro. The Spectrogram tool is offered in both 2D and 3D versions. The 3D Spectrogram includes all the functionality of the 2D version and adds powerful hardware-accelerated 3D plotting capabilities including a live 3D surface plot. A 3D upgrade is available to those who opt to purchase the 2D version.

3D Spectrogram

The real-time Spectrogram plots FFT-based spectral data versus time in a colorful surface plot. Signal magnitude at each time and frequency is represented by color. Use single-finger tap and drag to place a data cursor within the plot. When the cursor is visible, details regarding time, frequency, and magnitude will be displayed above the plot.

Main Features (available in both versions of the Spectrogram tool:

  • Frequency resolutions between 1 Hz and 50 Hz, depending on sample rate, may be specified for audio input (between 1 Hz and 10 Hz for the built-in accelerometer).
  • Input data can be windowed with one of 7 different FFT data window types.
  • Spectrogram data can be captured over time periods ranging from 2 to 20 seconds.
  • Lin, log, and dB magnitude scales with Up, Down, or Full auto-scaling.
  • Lin and log frequency scales.
  • Fractional-octave band frequency smoothing in 1/6, 1/12, and 1/24-octave bands.
  • Cursor peak track can track peaks in time, frequency, or both.
  • Color scale bar graph enables manual adjustment of magnitude scale and offset. The color scale can also be hidden.
  • Data may be exported to CVS, MAT, or TXT files for post processing or plotting. Optionally, include GPS location information with exported data. (The data export option is included in SignalScope Pro. It requires the Data Acquisition upgrade, sold separately, in the standard version of SignalScope.)
  • Optionally save a high-resolution PDF file of the spectrogram plot, or save an image to your Photos library.

3D Spectrogram Features:

  • Choose between 2D and 3D surface plots. Each plot can be drawn live (in real time).
  • Trackball-style 3D rotation of the 3D surface plot, just by dragging a single finger across the plot.
  • Tap with a single finger to place a cursor within the 3D plot.
  • In 3D, the cursor outlines the time and frequency slice associated with its current location.
  • Optional grid planes for each axis (magnitude vs. frequency, magnitude vs. time, and frequency vs. time) are drawn at the bounds of the 3D plotting region.
  • By default, the 3D spectrogram is drawn as a surface and magnitude values are represented by both position and color. The surface can be turned off, which allows data to be drawn only as a mesh.
  • The 3D spectrogram data can be seen as a solid-colored mesh (the mesh draws nothing between its lines or points). The mesh can be overlaid on the surface or drawn alone.
  • The mesh can be drawn as lines in time, lines in frequency, or lines across both time and frequency. It can alternatively be drawn as a series of dots, each one representing a single spectrogram data point.
  • When only viewing the 3D spectrogram data as a mesh, the time and frequency slices outlined by the cursor show through the mesh, making it very easy to see them in the midst of the rest of the data.

Also new in SignalScope and SignalScope Pro:

  • GPS coordinates, altitude, and accuracy may now optionally be saved with FFT, Spectrogram, or Oscope data when exporting to a data file (Data Acquisition Upgrade required in SignalScope).
  • Downloaded frequency response data for connected microphones will automatically be saved in a file in the Frequency_Response_Data folder to make it easier to access at a later time.
  • Smarter selection of the maximum frequency when FFT data smoothing is enabled.
  • Fixed an issue with Full Autoscale in the FFT analyzer.
  • Other minor cosmetic improvements and bug fixes.
