Changes in V5.20.3:
  • Remember and restore the state of the ASIO secondary output selection
  • Allow smoothing to be applied to RTA data (previously could only be applied to Spectrum data)
  • Added a Resistance trace to the Impedance & Phase graph to show the real part of the impedance
  • Bug fix: If multi-input capture was selected soundcard calibration would stop on the Measure dialog
  • Bug fix: The watermark text field in the View settings was blank after restart
  • Bug fix: SPL values in measurements exported as text only had 1 decimal place
  • Bug fix: Exporting the min phase IR as WAV or TXT would produce an exception if the min phase response had not already been generated
  • Bug fix: The search for D&D 8c speakers would terminate prematurely if a network interface being checked did not support multicast
The automatic update notifications will be re-enabled next week.
V5.20.2: A small update to add some checks to detect invalid impedance calibration results and fix a cosmetic bug on the Measure dialog.

  • Check for mono input data in impedance measurements
  • Check scale of measurement input vs ref input in impedance short circuit calibration to detect invalid results
  • Bug fix: Rinput and Rleads labels and controls could appear on the Measure dialog when measuring SPL
This is the official release of V5.20, the version number is 5.20.1 to distinguish it from the release candidates. It will only be available here for the next week or so, then I will also add it to the REW website and enable the version detection to report it as available on REW startup. It has taken a tad longer than I expected to release 5.20 (more than 2 years longer!) but on the plus side it does have a lot of new features. :)

There are a few changes from V5.20 RC15:

  • There is now a "dB Average" button in the All SPL graph controls that averages the dB values of the selected traces (e.g. +5 dB and - 5 dB average to 0 dB). It may be useful when averaging measurements to determine an EQ target.
  • The current sample rate is now shown in the RTA window title
  • The tolerance for channel gain mismatch on impedance open circuit calibration has been widened to 2 dB and I have added help text on how to balance channel gains
  • Bug fix: Long comments could push buttons out of view on room sim image capture dialog
  • Bug fix: The TS params calculated QMS figure was too high and the RMS figure was too low
Changes in V5.20 RC15:

I couldn't resist slipping in one more feature before the V5.20 release, so the waterfall and spectrogram now have a Burst Decay mode. The Burst Decay mode provides a way to more easily distinguish resonances of similar Q but different frequencies. It does this by showing the way a Gaussian-shaped tone burst at each frequency would decay, but along an axis denoted in periods of the frequency rather than time. On a period axis the extent of a decay is the same for resonances of the same Q regardless of the frequency of the resonance. The plot is produced by convolving the windowed impulse response (using whatever current window settings have been applied to the measurement) with a complex Morlet wavelet analytic signal (a Gaussian windowed complex exponential) to extract the decay envelope then resampling that decay on a period-based scale. That is repeated at 48 points per octave across the frequency span of the measurement, with 10 Hz as the lowest frequency allowed and the burst bandwidth below half the sample rate as the highest.

Other changes:
  • Added an Analysis preference to choose whether the System delay figure for loopback measurements is based on the relative timing of the measured and loopback IR peaks (the default) or either the estimated IR delay relative to the loopback when the peak is close to the IR start or the estimated IR start time relative to the loopback when the peak is later (limited bandwidth devices). The delay figure for the acoustic timing reference always uses the estimated IR delay/estimated IR start.
  • Adjusted threshold for using more compact layouts so it is used for display height (or scaled height) of 720 pixels or less
  • Limit the series R for capacitor component model fits to 1 ohm maximum for caps below 100 nF
  • Bug fix: Decay graph would generate an exception if the slice interval was more than the window length in CSD mode

V5.20 RC14 changes:

This build has the last of the changes I wanted to incorporate ahead of the V5.20 release. There are a set of updates for the Pro upgrade's multi-input capture mode, a more extensive set of options for generating minimum phase responses and a few other tweaks.

Multi-input capture
  • Added a button on the Measure dialog to configure the SPL alignment and weighting of multi-input capture measurements
  • Added a button on the RTA input selection dialog to configure the SPL alignment and weighting of multi-input captures
  • Added a button in the SPL & Phase graph controls to adjust the SPL alignment and weighting of multi-input capture measurements
  • In multi-input capture mode the RTA can show the first 16 inputs being captured in addition to their rms average
  • In multi-input capture mode the level meters can show the first 16 inputs being captured
  • Multi-input RTA measurements are saved in the same multi-input average format as sweep measurements, showing the span of the individual inputs as an underlay
  • Text exports of multi-input capture measurements can optionally include each input as well as the average

Generating minimum phase
  • Generating minimum phase may now include the effects of any calibration files in the magnitude response used to produce the minimum phase
  • Minimum phase can be generated for measurements which do not have an impulse response (e.g. responses imported from text files), it creates or replaces the phase response with the minimum phase response and gives the measurement a minimum phase impulse response
  • Low and high frequency tails can be added to responses for minimum phase generation
  • Added Ctrl+Alt+M shortcut to show the new Generate minimum phase dialog

Other changes
  • Moved the relative gain and phase panel from below the level meters into its own frame, accessed via the Tools menu
  • Added an option to switch orientation in the the level meters right click popup menu
  • The Level meters panel is resizeable in width and height
  • Added an option in the All SPL graph Align SPL dialog to use the average dB SPL of the selected measurements as the target
  • Show a warning if the ASIO driver sample rate is not the rate that was requested
  • When removing delay from soundcard calibration measurements round to the nearest sample, sub-sample delay estimates on soundcard responses tend to be slightly in error due to the reconstruction and antialias filters
  • A phase column is not included in text exports if the measurement does not have phase data
  • The RTA input selection dialog is no longer modal
  • Revised the trace plotting order on some of the graphs
Bug fix: Component model could generate an exception for some capacitors
Changes in V5.20 RC13:

  • Added an action in the EQ window filter tasks pane to create a new measurement from the current filters
  • Software equalisers (currently the Generic, TMREQ and AU N-Band EQ options) now run at the sample rate of the measurement they are applied to rather than a fixed rate
  • Changed the capacitor component model to add an option to model dielectric loss, when that option is not selected a series RLC model is used
  • When Individual cal file per input is selected each input of a device can be individually calibrated for SPL level
  • Added a button on the Impulse graph Offset t=0 dialog to set the cumulative IR shift to zero
  • Changed macOS look and feel to FlatLAF to get a properly functioning folder chooser (when not using the native-style macOS file dialog per the View preference). The Java file chooser under FlatLAF is a bit faster to appear than the native dialog and does not seem to suffer the disappearing dialog problem that occurs on some macOS installations.
  • Added further entitlements to get consistent mic access on macOS, to force a mic access prompt run tccutil reset Microphone from a terminal before starting REW

  • Bug fix: With multi-input capture SPL meters 2, 3 and 4 showed the input span in the title instead of their individual input name
  • Bug fix: Exporting impulse response as wav with two impulses of different windowed lengths could cause an exception
  • Bug fix: Multi-input sweep measurements did not apply any default FDW selected in the Analysis preferences to the individual inputs before averaging
  • Bug fix: The System delay figure shown on Info panel was not updated if the t=0 position was changed
  • Bug fix: Generate measurement from predicted could produce an exception if the equaliser in the measurement was different from the default equaliser for new measurements
  • Bug fix: Generate measurement from predicted had incorrect results above half the sample rate of the selected equaliser if the measurement sample rate was higher
This is identical to the previous RC12 but fixes the entitlements for mic access. It is a universal binary with native Java runtimes for both Intel and M1 macs.

Changes in V5.20 RC12:
  • Added an input selection button on the RTA
  • Added a control in the SPL & Phase graph to adjust the measurement to a specific average SPL value over a defined frequency span
  • Added a control in the All SPL graph to adjust the currently selected SPL measurements to a specific average SPL value over a defined frequency span
  • Added an option on the export all measurements as text dialog to use one file or individual files
  • Added an action in the EQ window filter tasks pane to create a new measurement from the predicted response
  • The currently active entries in the Cal Files preferences are highlighted
  • The RTA can now show harmonic distortion figures when the source is an REW-generated tone burst
  • The RTA spectrum view peak SPL figure for tone bursts is based on unfiltered data (unlike the CEA burst result which uses a 1/3 octave filter)
  • Add the source settings to the meas notes for measurements generated from the room simulator
  • Updated to install4j V9
  • Bug fix: Component model could give incorrect results for some inductors
  • Bug fix: The bottom of the notes area scroll bar was not visible on the measurement panel for measurements which did not have a Change cal button
