V5.19 beta 1 28th January 2017
  • Added a distortion overlay graph
  • Allow up to +/-999 dB data offsets
  • Use Arial Unicode MS under Windows when language is not English to try and improve support for Cyrillic characters
  • Set tool tip dismissal time to 5 seconds (from 8)
  • Changed default for RT60 to be one-third octave
  • Changed default for Decay slices to be filled
  • Changed default equaliser on first installation to Generic
V5.17 beta 15 23rd December 2016
  • Added a timing reference selector on the measurement dialog
  • Append -MP to the filename of exported minimum phase impulse responses
  • Ensure peak in an exported impulse response is at 1 second if the export has only one channel
  • Added a distance units selector to the View preferences
  • Changed default replay buffer for OS X to 16k and generated a new key to reset it to 16k for existing installations
  • Modified combo box UI so that the selection list is wide enough for all items in the list rather than truncating them at the box width
  • Bug fix: Length formatter didn't cope with negative distances when using feet and inches
  • Bug fix: Fractional sample shifts in the IR t=0 position did not update the window reference timing correctly
V5.17 beta 14 4th December 2016
  • Added THD and THD+N figures for the 20 Hz to 20 kHz span to the RTA distortion panel
  • Modified xml format of rePhase filter files to included enabled status, use constant Q and improve frequency resolution
V5.17 beta 13 3rd December 2016
  • Added command to export filter settings as text to filter tasks pane
  • Changed tool tip position for the graph trace selectors to move them right so they do not obscure the selector check box
  • Added a secondary ASIO output selector to the signal generator
  • Changed filter export to use decimal point as delimiter and remove grouping regardless of locale
  • Added options to save and load rePhase filter settings to and from an XML file
  • Bug fix: Target match optimiser could fail in some circumstances
  • Bug fix: Cal file loader could fail without an error message if an attempt was made to load a binary file
V5.17 beta 12 2nd November 2016
  • Added a rePhase equaliser setting, 17 constant Q parametric filters
  • Bug fix: White PN ignored LF Limit when using Custom range
  • Bug fix: Measurement name could end up with multiple annotations, annotations are no longer shown in the name in the measurement panel, only in the graph legends
  • Bug fix: Measurements after the first would fail if the Levels panel was displayed
V5.17 beta 11 11th October 2016
  • Added multichannel output selection capability, works on OS X (may work on Linux also) but not supported by Windows JRE
  • Added a View preference to show [FDW] in the measurement name if a frequency dependent window has been applied, preference is enabled by default
  • Disabled soundcard calibration when using a USB microphone (it is not applicable)
  • Set lower limit for capture monitor level meters to -60 dBFS (was -50)
  • Removed the inter-channel meters from the soundcard preferences and capture monitor
  • Updated bundled JRE to 8u102
  • Bug fix: valid start freq for measurement was not set correctly when loading a measurement that was smoothed
V5.17 beta 10 12th September 2016
  • Added input inter-channel relative gain and phase figures to the VU meters panel, active when signal generator is playing a sine wave
V5.17 beta 9 10th September 2016
  • Added sample rate to excitation description for impedance measurements
  • Bug fix: Fixed scaling error on merge B to A when measurements had different SPL calibration offsets
  • Bug fix: Impedance measurements can sometimes be affected by an inter-channel timing difference, possibly related to running the card at a different rate to the REW rate. If a timing difference of 1 sample or less occurs REW compensates for it, if more than 1 sample a warning is shown.
V5.17 beta 8 10th August 2016
  • If a USB mic is selected without having a cal file with sensitivity data loaded the SPL calibration status is cleared
  • If SPL calibration is attempted with a USB mic selected that doesn't have sensitivity data ask for the mic cal file
  • Added an equaliser setting for the Rockford Fosgate 3Sixty.3
V5.17 beta 7 18th July 2016
  • Bug fix: Fundamental response for distortion calculation could be incorrect (beta 5 bug)
V5.17 beta 6 14th July 2016
  • Input High Pass filter selection on soundcard preferences was previously only applied for measurements, now applies to any use of the input data
  • If a frequency-dependent window is applied its effect is shown on the windowed IR trace, included in a windowed IR export and trace arithmetic will use the FDW impulse
  • Added a peak trace to spectrum plots
  • Added peak hold and peak decay controls to the RTA window
  • No longer clear SPL calibration status if input changes - temporary changes during startup may have been causing issues for some users
  • Bug fix: With ASIO drivers the timing ref output selector was shown when first opening the measurement dialog even when not using a timing reference
  • Bug fix: RTA and Spectrum traces were drawn 3 dB lower than they should be when the axis was set to dBFS and the View option for "Full scale sine rms is 0 dBFS" was selected
V5.17 beta 5 2nd July 2016
  • Modified RT60 calculation to cope with responses that have been truncated before they reach the noise floor
V5.17 beta 4 2nd July 2016
  • Modified RT60 calculation to better cope with responses that have a large initial decay
  • Added a secondary output selector to the measurement dialog when using ASIO drivers
  • Bug fix: Schroeder trace on Filtered IR graph was not updated when filtering settings changed
V5.17 beta 3 27th June 2016
  • In distortion controls the options to limit norm. to 30 dB below peak and to use harmonic frequency as ref are only enabled when plotting normalised to fundamental as otherwise they have no effect
  • Removed 10 Hz lower limit on white periodic noise
  • Added option to use 64-bit FFT processing on RTA when need to resolve below -160 dBFS, e.g. analysing 24-bit digital data paths
  • Adjusted dual tone f1 level to match the sig gen rms level setting (means clipping occurs if level is set higher than -9 dBFS for 1:1 signals or -6 dBFS for 4:1 signals)
  • Bug fix: RTA rms level and average count not shown in correct position (beta 1 bug)
  • Bug fix: Graph axis selector could disappear when trying to select from dropdown on OS X
V5.17 beta 2 1st June 2016
  • Bug fix: graph controls window was not displayed properly (beta 1 bug)
V5.17 beta 1 31st May 2016
  • Added delay info to measurement notes when using loopback or acoustic timing reference
  • Added buttons on the graph to quickly switch between two preset frequency spans that are defined in the View preferences
  • Increased precision of distance readout on zoom box
  • Bug fix: distortion data was not generated for first measurement after startup and was wrong for first measurement after changing sweep span
