Changes in V5.20 beta 35:

The room simulator and the alignment tool have been updated for this release.

Room simulator

It has been quite a while since the room simulator was updated, so there are a basket of changes.

A set of 5 presets has been added, which are remembered for subsequent startups. A comment can be entered that is saved with the presets. There is also a button to capture the current Main mic response and keep it on the graph as a reference as changes are made.

There are buttons to create measurement files from the simulator output that can then be saved as mdat files, either a single file showing the response with all sources active or individual files for each source. In both cases the response saved can be either that of the main mic position alone or an average of all the selected mic positions, showing the span of the results as an underlay.

There are check boxes to keep the L and R speakers symmetric across the width of the room (so moving one will move the other to maintain symmetry), or to allow them to be moved as a pair keeping the distance between them the same. Buttons have been added to place the head mid-width across the room or midway between the L and R speakers. If the room has left and right speakers the angle between them at the head is shown when the mouse is over the head position. There is now a check box to use the same delay for all subwoofers, rather than having to adjust each individually.

Finally, there are buttons to capture images of the room view panel and the response graph.

Alignment tool

The alignment tool has a greater delay range of +/- 50 ms and has gained some additional buttons to (hopefully) help with phase alignment.

The Level phase at cursor button will shift both measurements by the same amount (so no relative delay change, and no effect on aligned copies or the aligned sum) so that the phase of the first measurement is more or less horizontal around the cursor frequency. That should make it easier to manually align phase, removing the slope due to the local group delay of measurement 1.

The Align phase slopes at cursor button adjusts the delay of the second measurement to align the phase slopes around the cursor frequency, so both have the same local group delay. Aligning slopes rather than the phase itself can make it easier to spot when one measurement could be inverted for a better phase match.

The Align phase at cursor button adjusts the delay of the second measurement to align the phases around the cursor frequency.

The graph cursor is now shown in the alignment tool phase graph, it follows the cursor frequency in the alignment tool magnitude graph. The alignment tool phase responses also update if the window settings of a measurement being aligned are changed.

There are a couple of minor changes:
  • The EQ window target settings panel has gained a right click menu to copy and paste target settings from one measurement to another
  • Scope image captures are now drawn at the desired width rather than scaling an image from the scope panel width, so the captures have better resolution

Bug fixes in this release are:
  • When a measurement was selected on the alignment tool dialog the currently selected alignment smoothing was not applied to it
  • When the alignment tool smoothing was changed the phase traces did not update correctly to include the current delays
  • Mic cal C weighting selection was not applied to cal data after a restart
  • On macOS or Linux output channel selections could be invalid after changing to a device with fewer channels than the previous device
  • Update the J-test displayed frequency figure when the sample rate changes
  • Removed code that tried to compensate for the effect of input volume changes on SPL calibration
  • An exception could occur when the SPL logger was started
Changes in V5.20 beta 34:
  • Added a jitter test signal to the signal generator in the Tones group
  • Added a right click menu for the waterfall and spectrogram controls to copy and paste settings between measurements
  • Added check boxes on the waterfall and spectrogram controls to enable or disable the automatic regeneration of the plot when settings change
  • Moved the ISO 3382 parameters on the RT60 graph data panel into a separate window
  • Added an Analysis preference (selected by default) to use only the right hand IR window width when deciding the minimum valid frequency in the response
  • Added a View preference to use dashed strokes on overlay graphs
  • Added a check box on the merge operation to optionally blend the merge over 1/3 octave either side of the merge frequency
  • RTA mic cal data was only updated when the RTA started, now updates if cal changes while RTA is running
  • Stepped sine continues to measure distortion even if "Show distortion" button is deselected
  • Improvement in RT60 Decay calculation
  • Small improvement in RT60 calculation for longer decays
  • Bug fix: Group delay trace could be incorrect for log spaced data with 1/48 octave smoothing
  • Bug fix: ASIO driver selection could fail for a sample rate causing an exception
  • Bug fix: Extra settling time may be required for stepped sine measurements when using a silence interval
Changes in V5.20 beta 33:
  • When multiple measurements are loaded load them as a set then select the last rather than adding and selecting each individually. This speeds up loading by not triggering calculations that may be required when a measurement is selected, for example generating a spectrogram when on the Spectrogram graph page
  • Suppress low quality RT60 decay results
  • Bug fix: Dragging wav files onto the RTA for processing was not working
  • Bug fix: Loading a file with multiple measurements while on the Spectrogram graph with the Wavelet spectrogram selected could result in an exception
  • Bug fix: Could not select the manual settings button on RT60 decay
  • Bug fix: Guard against out of range error when fetching harmonic phase during stepped sine measurement

Changes in V5.20 beta 32:
  • Bug fix: Alignment tool aligned copy had the delay applied with the wrong sign
  • Bug fix: Delays in the comments for the Alignment tool aligned sum measurement had the wrong sign
  • Bug fix: Ohms axis could become selected for SPL measurements on the SPL & Phase graph when there was a mix of SPL and impedance measurements
  • Bug fix: Limits dialog was not working properly for new axis types

Changes in V5.20 beta 30:
  • Added options to step in frequency or level to the Stepped Sine dialog
  • Added a stability test for the stepped sine measurement to optimise speed
  • Added a distortion threshold beyond which stepped sine measurements will be stopped. Distortion must drop below the threshold to arm it.
  • Made the stepped sine dialog non-modal so RTA window remains accessible for graph adjustments, but RTA controls are disabled to avoid changes that would interfere with the measurement
  • Added a new method of RT60 calculation based on frequency domain processing and a graph "RT60 Decay" to show the results
  • Allow multiple Y axis unit types for all relevant graphs (dB SPL, dBFS, dBu, dBV, dBW, V, W)
  • Did away with the plot normalised option for distortion graphs, happens automatically if dBr or percent selected as Y axis
  • Changed SPL & Phase "Invert polarity" checkbox to a toggle button
  • Added filter order selection for the RT60 and Filtered IR graphs, default is 6th order, max is 48th (filters are Butterworth bandpass)
  • Added the equaliser sample rate in the heading of the equaliser selection panel
  • Set Storm Audio EQ lower frequency limit to 16 Hz
  • EQ panel waterfall colour scheme is only disabled if live waterfall updates are selected

  • Bug fix: Cal file parsing could be confused by content in comments
  • Bug fix: The delay figure in the measurement notes for aligned measurements had the wrong sign
  • Bug fix: Selecting the custom range option for the pink or white random noise with both the low cut and high cut boxes not selected would cause an exception
  • Bug fix: An exception could occur if the file chooser file filter was set to "All files"
Changes in V5.20 beta 29:
  • Replaced the All SPL parametric sum feature by a more general Alignment Tool
