Reduced warning threshold for timing reference to -45 dBFS (from -30dBFS) and only show the warning once in a session
Added a window selection for the stepped sine dialog, Rectangular recommended when the generator and input are on the same device
Added an option to show or hide the filter numbers along the top of the EQ window's filter adjust graph
Added a warning in the help about using long sweeps if input and output are not on the same device due to potential problems from sample clock differences
Added a soundcard input impedance setting on the Measure dialog for impedance measurements
Added view preferences for keeping the SPL meter, VU meters and signal generator on top of other windows
Bug fix: Output level control didn't increment or decrement properly on the volts scale for small voltages
Bug fix: If a measurement was opened while on the waterfall or spectrogram graph the waterfall or spectrogram would be generated but not displayed
Bug fix: Timing signal detection could fail despite good signal level
Bug fix: Waterfall and spectrogram generation could be incomplete on some devices
Bug fix: Stepped sine did not operate correctly with 0% overlap for FFT lengths above 64k
Bug fix: UMM-6 volume compensation was incorrect on macOS
Bug fix: SPL limit on Measure dialog couldn't be adjusted
Don't show smoothing selection on captured graph images, any smoothing selected can be seen in the legend if included
Improved positioning of data panels on captured graph images and reduced panel opacity
Added an option to include date and time on graph captures
Improved icon resolution on macOS retina displays
Added a set of icons for the dark colour scheme
Windows installers now provide an option to allow multiple instances
Windows installers prompt to download a Java runtime during installation if one is not available rather than including it in the installer
Updated to JRE 1.8.0 build 202
Bug fix: Some Scope settings were difficult to read when using the dark background
Bug fix: If the input device did not provide any data it could be difficult to quit the Measure dialog
Bug fix: Timing offset controls were overlaid on RLeads control if timing mode was loopback before selecting Impedance measurement
Bug fix: Timing offset controls were disabled when measuring from file
Bug fix: Graph capture comments were not being wrapped properly
Bug fix: Soundcard calibration result notes were missing
Bug fix: If FDW was enabled by default the cal files were not applied when the measurement was generated, but would be applied on any subsequent window application
Gave the signal generator a revamp and added a signal waveform preview
Added fade in and fade out controls to the linear and log sweep signals
Added AES17-2015 MD and DFD presets to the dual tone signals
Changed sig gen level control behaviour for dual tone signals, the level setting now reflects the rms level of the combined signal rather than the rms level of f1
Added a selection of multitone test signals
Allow RTA lengths up to 1M
If the RTA update interval is more than 1 second show the percentage progress for the next update on the record button
Provide separate buttons in RTA to save current, peak and both traces
Added dBu and dBV RTA Y axis options and a level calibration capability
Added dBW RTA Y axis option and a control for the reference resistance for the dBW values
Added an option to show RTA distortion ratios as either percentages or dB
Expanded the RTA IMD results to include Total Distortion + Noise
Added RTA figures for Total Distortion + Noise and SNR when using the multitone test signals
Added two Dolph-Chebyshev RTA window options, with side lobes 150 dB down or 200 dB down
Added an A weighted dynamic range figure to the RTA THD results
Added a display of the peak sample value in the RTA rms input levels box
Determine a more accurate value for the IR peak when it lies between samples
Improved precision of Estimate IR Delay
Made the acoustic timing reference delay estimates more precise
Improved inter-sample rendering of impulse responses so the waveform retains the same shape regardless of fractional sample offsets,
to achieve this the IR is oversampled using a method selected by the new IR oversampler option in the Analysis preferences.
Changed behaviour while capturing the noise floor before a sweep measurement. Used to play a 1 Hz sine at -150 dBFS, then stop the generator and start it again to play the measurement sweep. Now dithers the lsb before the sweep starts without having to stop and start the generator. Should help ensure digital inputs are active and locked to the generator before the sweep starts and prevent issues with audio drivers due to rapid stopping/restarting of the audio lines.
Decay, waterfall and spectrogram plots generate automatically when the graph is selected
Added a button in the Impulse graph controls to set t=0 at the cursor position (also activated by Alt+z when the control is visible)
Added a button in the Impulse graph controls to set t=0 at the IR start (also activated by Alt+y when the control is visible)
Added a button in the All SPL graph controls to set t=0 at the IR start for all the currently selected measurements
Added an option to normalise the step response to the IR peak value rather than the step response peak value
Changed the Merge operation to use the window settings of the B (low frequency) trace rather than the A trace
Show more decimal places on the window reference time as it gets closer to zero
Added an option to export the impulse response with EQ filters applied
Changed the Analysis options for setting t=0 to use either the IR peak, the start of the IR (based on it first exceeding 10% of the peak level) or the estimated IR delay
Added 2M and 4M sweep options, useful for improving signal to noise on high sample rate measurements
When importing impulse responses disabled the feature that rotated the peak to the middle of the data if it was found very close to the start of the data
Added all-zeroes check for imported audio files
Switched level checks to using Pink PN instead of random pink noise for faster and more accurate level readings
Persist the choice of sub or main speaker for levels check in SCSettings
Improved rendering of scope traces
Made the legend panel right click menu available in all graphs, not just overlays
Show a warning if the timing reference peak level is high
Increased span of level meters in soundcard preferences to 100 dB
Added a note in the View preferences to identify settings that are applied after restart
Removed heading text from TS parameters results panel to reduce height of window
Added a View preference for the font size used for graph axes in graph image captures
Reapply ASIO sample rate after reloading the ASIO driver
REW now requires a Java 8 JRE, Java 7 is no longer supported
Bug fix: FDW phase correction for win ref time offset from zero was inverted
Bug fix: Generating a min phase measurement did not take account of any frequency dependent window applied
Bug fix: Mouse wheel zoom did not maintain aspect ratio when zooming out
Bug fix: Input name disappeared from RTA window title when settings were changed
