11.5.18
2022-10-16
- Corrected an issue with Unicode text characters that could prevent MAT files from being successfully opened by MATLAB 2020b or newer.
- Minor cosmetic improvements.
11.5.15
2022-09-12
- Fixed a text and audio data export bug that would cause the app to crash when there was no data in some analyzers. This could happen when triggering was enabled and no data was acquired on some or all channels.
- The spectrogram cursor peak track works correctly with spectral smoothing applied. Also, when changing the peak track selection in various tools, the plot is updated immediately when the tool isn't running.
11.5.14
2022-08-13
Extra, temporary copies of files loaded from external sources (e.g. iCloud Drive) no longer accumulate in the Inbox_2 folder.
11.5.10
2022-06-22
Fixed a bug in which the Data Recorder, Max Levels, or XY Scope might not start running as expected.
11.5.9
2022-04-18
- Fixed a bug which could cause Octave data to be exported with incorrect values for individual frequency bands. The problem occurred when the bandwidth was changed while the analyzer was running and then data was exported before re-starting the analyzer.
11.5.8
2022-04-08
- Fixed a bug with input sometimes not starting in the calibration screen.
11.5.6
2022-02-15
- It is now possible to select loaded data for cursor peak track and horizontal cursor bar.
- Fixed a bug that prevented the FFT Analyzer from loading selected data from loaded data files at launch.
- Fixed a bug with the cursor horizontal bar and peak track selection menus.
- Minor bug fixes and performance enhancements.
11.5.5
2021-12-29
- A list of the most recent articles and news items on the Faber Blog is now accessible from the Info menu.
- Minor bug fixes.
11.5
2021-10-05
- Auto-start triggering is now an option in the Octave and Data Recorder tools. Analysis (Octave tool) or recording (Data Recorder tool) can be set to begin only after a user-defined instantaneous signal level threshold is reached on the designated trigger channel. The trigger channel can be selected from among all input and output channels available on the selected input and output audio devices. It can be chosen independent of the channel(s) selected for analysis or recording. Up to 100 ms of data can be stored prior to the trigger event (pre-trigger delay).
- More robust triggering in all tools that support it.
- The Signal Level Meter, Signal Octave Analyzer, Max Levels, and Data Recorder tools now support 1/8 and 1/10 second increments for the auto-stop duration.
- Mac: Improved support for zoom/pan in line and surface graphs via two-finger pinch/drag gestures on the track pad. The mouse scroll wheel works for panning zoomed graphs.
- Fixed a bug which disabled output channel polarity inversion in the Sig Gen tool.
- Additional bug fixes and cosmetic/user experience improvements.
11.4
2021-07-31
- Improved support for audio interfaced with DC-coupled inputs, including optional DC offset correction and DC blocking filters per input channel.
- Enhanced real-time audio processing for better performance and better measurements at higher sample rates. On the Mac, the improvements to audio handling also eliminate some bugs that could cause the app to crash or hang. The Mac version also properly recognizes changes in the list of connected devices, such as when a device is connected to or disconnected from the Mac.
- In the Signal Generator tool, DC offset can be applied independently to left and right output channels in the periodic signal generator. This DC offset can apply to the noise and sweep type signals only when the periodic signal type is switched on. You can generate a DC output signal (on hardware with DC-coupled output channels) by setting the periodic signal generator’s frequency to 0.0 and using the DC offset controls to set a DC output value.
- The Signal Generator’s sweep/chirp signal can be generated in the time domain or in the frequency domain. Frequency domain synthesis offers a truly flat (or linear) spectrum for single-channel frequency response magnitude measurements.
- Additional bug fixes and cosmetic/user experience improvements.
11.1
2020-12-31
- Built for iOS 14 and macOS 11, Big Sur.
- Mac: SignalScope Advanced 2020 is now a Universal macOS app, including native support for both Intel processors and Apple silicon.
- Mac: Audio device selection is now independent of the system audio input and output devices. Input and output devices can be selected independently without interfering with other audio apps or system settings.
- Mac: Audio sample rates may be specified independently for input and output devices (unless the same device is selected for both input and output).
- Mac: A graphics bug has been fixed, which sometimes caused graphing problems on iMac models with NVIDIA graphics cards.
- iPad/iPhone: Nominal microphone sensitivities updated to include new iPad Air, iPhone 12, and iPhone 12 Pro.
- Minor bug fixes and cosmetic improvements.
