- The IO Device Configuration menu features some changes related to audio sample rates. We have found that in recent versions of iOS, the sample rate will almost always stay set to 48 kHz when the audio input and output routes do not belong to a single audio hardware device. So, when you want to run data analysis or acquisition at higher or lower sample rates for a dedicated input device, like a USB microphone or accelerometer, this iOS behavior makes that impossible. To address this issue, SignalScope now allows you to disable audio output so you can operate your input device at the desired sample rate. With audio output disabled, virtual output channels are still available for analyzing signals from the Signal Generator or File Player tools. - In addition to the option to operate input devices at different sample rates, SignalScope now presents a list of supported sample rates for select hardware devices instead of a text field for manual entry of the desired sample rate. So, if you’re performing vibration measurements with e.g. a Digiducer USB accelerometer, you can select from a list of known supported sample rates (between 8 and 48 kHz) instead of using trial and error to manually find a supported sample rate that more closely matches your analysis needs. - An option to disable audio output mixing with other apps has also been added. In earlier versions of SignalScope, output mixing was always enabled. This option doesn’t have any effect when audio output is disabled. - Fixed an issue in which the sample rate of the Signal Generator tool might not be immediately updated if the sample rate changed while the tool was running. - Fixed an issue that would sometimes stop the Signal Generator tool if the sample rate changed while the tool was running. - Addressed some cosmetic issues.

- The IO Device Configuration menu now includes a Soft Gain option in the output options section. The software gain is a digital scale factor applied to all output signals just before they are sent to the hardware. The intent of this is to support listening to low level signals (play-through or internally-generated) in potentially noisy environments. - Fixed some cosmetic issues.

- More general improvements, including more informative alerts in certain cases when loading a data file fails. - Fixed a crash that sometimes occurred when Run In Background was switched off.

- Improved handling of data and audio files. On newer versions of iOS, external files (e.g. on iCloud Drive) can be opened in-place instead of being copied into the app sandbox before opening. - Significant improvements have been made 'under the hood' to ensure that the app runs well on the newest operating systems. - Other minor cosmetic and stability improvements. - Several improvements have been made for when SignalScope is run on Apple Vision Pro: - The local IP address is updated correctly for sharing data files from SignalScope through a standard web browser (using SignalScope's built-in http file server). - Nominal Vision Pro microphone sensitivity has been added. - Zoom, pan, and swipe gestures now work much better.

- Improvements to data file import. - Octave Analyzer performance improved with high sample rates (e.g. 192 kHz), and auto-start triggering is more robust. - Improved auto-calibration behavior in the File Player tool. - Other cosmetic and minor improvements. - Stability improvements.

- Support added for Dayton iMM-6C measurement microphone, including automatic retrieval of calibration information after entering the product serial number. - Corrected a misplaced cursor issue in the Octave Analyzer when displaying secondary levels as well as data loaded from a file. - Fixed an issue that could prevent saving data to MAT files. - Other stability improvements.

- Support for a few basic Shortcuts (e.g Start, Stop, Save Data) to enable control of SignalScope via the Shortcuts app, Siri, or AppleScript. The Shortcuts feature requires at least iOS 16 or macOS 13.

- The Spectrogram now supports user-selected min and max frequencies. - The Spectrogram now supports graphing with time on the vertical axis (consistent with a typical LOFARgram). - The Spectrogram includes an Auto Stop function for stopping after a user-defined period of time. - When exporting Spectrogram data to a file, the magnitude data will be stored as decibel values when the dB scale is selected for magnitude values in the display settings. - Support added for the latest Digiducer USB Digital Accelerometer models. - Other cosmetic and minor improvements.

- Help files now adjust to dark mode. - The Recorder tool no longer reports a problem when audio file metadata is successfully saved in the file. - Fixed a bug which hid the last physical input channel's gain controls on Mac. - Other stability improvements.

- Fixed a bug that would cause SignalScope to crash when exporting Octave log data to a text file (csv, txt).

- Frequency weighting is now supported for non-acoustic signals in the Meter tool. - Support for the miniDSP UMIK-2 and the Dayton UMM-6 USB measurement microphones has been improved. - Some potential crashing bugs were fixed. - Various cosmetic improvements

- The built-in web server has improved handling of data files that have non-ascii characters in their name. - Reference curves in the Octave Analyzer tool are drawn correctly when changing upper and lower frequency limits of the graph. - Corrected some cosmetic issues with data loaded from a file in the Octave Analyzer tool. - Other cosmetic improvements

- Corrected an issue in which the frequency labels were drawn misaligned in the Octave analyzer tool. - Fixed multiple cosmetic issues on macOS 13 Ventura.

- Fixed a cosmetic bug in the Signal Generator on iPhone.

- The embedded HTTP server for accessing data files works more reliably on iOS 16. - An issue with data file preview showing the first previewed file again, when trying to preview a second one, has been corrected. - Other cosmetic/interface improvements

- Cosmetic/interface improvements to the Signal Generator - Corrected an issue with Unicode text characters that could prevent MAT files from being successfully opened by MATLAB 2020b or newer. - Other cosmetic/interface improvements

Removed the data import icon from the toolbar of several tools where it doesn't belong.

- The Spectrogram supports time scales up to 60 seconds. - The Spectrogram no longer automatically enables spectral smoothing when it starts. This is more convenient when working with a linear frequency scale. - A bug that would cause FRC (frequency response correction) to be reset in other channels when switching it on or off has been corrected. - FRD (frequency response data) import works more reliably for individual audio device channels. - Cosmetic improvements.
