Fix a bug that could cause issues with groups when exported speaker setups were imported
Several smaller bugfixes

Beta v0.6.0

Completely rework the way sound pressure levels are calculated
- Maximum achievable sound pressure levels are now calculated by CODA’s proprietary innovative and no-compromise realSPL technolgy
- Displayed / calculated SPL values are now maximum continuous or peak sound levels.
- Almost all algorithms, which e.g. also calculate third-octave band levels, have been revised
- Default SPL values shown are continuous RMS sound levels and can be changed to (continuous) peak sound levels (crest factor added) in the Preferences
Add “Bottom Height” and “Bottom Angle” readout
Fix a bug that would sometimes show an error message when opening System Optimiser
General performance improvements
Fix error when working with arrays which had templates “in the middle” deleted
- If you have an array controller (applies to all HPS/HSA/SVA) with three templates and delete the second one, the bug would occur
- This applied to both loading after storing arrays to files (venue files or source export files) as well as clicking the “X” button at the top of the controller editor window
Adjust the icon colour of System Optimiser to match other CODA software products
Add D5 speaker
Changed behaviour of Vertical Arrays when a speaker has no link group assigned
- Speakers which do not have a Link Group assigned are now muted instead of having a default preset assigned
Stimuli:
- EIA-426B and DIN-IEC 268 have been removed
- Available stimuli:
  White Noise (Periodic Noise)
  
  Pink Noise (Periodic Noise)
  
  Speech Noise (Male, 2020 as defined in IEC 60268-16)
  
  AES75-2022
  
  A-Weighted Pink Noise (Periodic Noise)
3D View
- New arrangement of the options for the displayed values
- From left to right:
  Stimulus
  
  Band (1/3 Oct (third octave), 1 Oct (octave band), Broadband (total level))
  
  Frequency
  
  Weighting (Z/A/C)
Microphones
- New concept: Mic Sets
  Microphones can be grouped
  
  This allows the easy and efficient use of several independent mic dialogues
  
  Microphones from previous version files are migrated to a group called ‘Migrated Project Microphones’
- Microphones can now be named
- Split into two modes: 2FR and SPA
  2FR is a dual channel FFT frequency response, most useful to optimise the frequency response of the system
  
  2FR can be normalised (level shifted) to some automatic or user defined value (setting the 0dB point)
  
  Options: Smoothing and Average Curve
  
  SPA is a spectrum analyser to evaluate the maximum achievable sound pressure level
  
  Options (from left to right):
  
  Smoothing
  
  Stimulus
  
  Weighting
  
  Band Mode
  
  ASD (Amplitude Spectral Density), quasi continuous version of Max SPL frequency response
  
  1/24 Oct
  
  1/3 Oct (third octave band)
  
  1 Oct (octave band)
  
  Average curve
  
  For the microphones themselves, the total sound pressure level (RMS) for the selected combination of options is displayed
Probes
- Probes are only available in 2FR mode
  Options are identical to microphones in 2FR mode
  
  Probes can be normalised (level shifted) to some automatic or user defined value (setting the 0dB point)
- Colours no longer change when the site angle of the array is changed and some speakers then no longer hit a surface.
- Button next to the speaker shows whether the respective speaker hits a surface and has a curve (red = does not hit a surface)
New window / panel: Maximum SPL
- This window determines the Max SPL setting (stimulus input level) for all other SPA calculations (Microphones / 3D view)
- This window offers a detailed analysis of the system’s headrooms
- Limiting factors can be found very precisely this way
- Options:
  Stimulus: Selection of the stimulus
  
  Mode: Automatic or Manual
  
  Default is Auto, where the system is driven in such a way that no loudspeaker is limiting.
  
  In Manual Mode, a manual input level of the signal (RMS) into the amplifiers can be set.
  
  manual mode can be useful for example if you’re either willing to sacrifice dynamics (you shouldn’t!) or if you’re assessing noise pollution when the audience is treated with a certain level below the maximum capability of the system.
- If the maximum input level is exceeded in Manual Mode (shown on the right), the red “OVR” light warns of this condition.

Beta v0.5.4

- For Windows and Linux, there is only a single binary
