MiRA Release Notes

Release - MiRA 26.04.50610

 

New features

Welcome EQ and auto-EQ in MiRA (available for Live and Ultimate licenses)

 

  • Automatically generate an optimized EQ correction curve from measured transfer function curves.
  • Includes standard and custom target curves and other options to conform the result to specific requirements
  • Comprehensive UI to edit the EQ manually, with a wide selection of filter shapes
  • Copy / paste EQ parameter directly to SPAT Revolution
  • Export EQ parameters or coefficients directly in LPIF format, RME TotalMix Room EQ, FabFilter ProQ4

 

Real-Time Handling of Multiple Simultaneous Input Streams (available for Studio and Ultimate licenses)

 

  • Support for unlimited number of input streams, with up to 24 channels by stream
  • Configure the streams with different speaker setup
  • Analyze these streams in parallel with multiple real-time tools.

 

 

Capture system (available for Live and Ultimate licenses)

 

  • In the system setup and for each session, create up to 4 computed curves, and assign captures or microphones to one or several of them. This enables monitoring and comparing multiple averages simultaneously.
  • Visualize your target curve directly in the Transfer function scope
  • Create computed curves capture with a new action “New computed capture” (shortcut Alt+Shift+Space)
  • Capture RTA data in addition to Transfer Functions. When Transfer Function is not present but Capture System and Magnitude Spectrum are, the system performs RTA‑based measurements—allowing measurement without a reference signal.
  • New “New sequential captures” action, to automate the measurement. Choose the signal type, the capture number, and wait time to auto‑record sequential measurements with the same microphone.
  • New auto-color system for captures, available by default.

 

Loudness metering scope (available for all licenses)

 

  • Added new PLR and PSR dynamics readings
  • Added DAW sync when using SampleGrabber (auto-pause / reset)
  • Refreshed UI with configurable measurement display
  • Added several additional loudness modes and threshold / alert value display
  • Added option to display measurement time and current momentary / short-term values

 

Additional Improvements

 

  • New I/O setup page, for clearer configuration and multi-streams management
  • New Daylight Mode UI
  • SPL mode added to Magnitude Spectrum and RMS metering (available in scope settings).
  • New possibility to use both SampleGrabber and Input hardware at the same time, enabling Studio and Ultimate users the possibility to analyze at the same time DAW input.
  • Various optimizations and UX improvements
  • Magnitude smoothing setting is now per-octave, mirroring phase smoothing.
  • A warning message is displayed when the SampleGrabber network connection is unstable, to avoid corrupted measurements
  • Reduced memory usage with Session and Studio licenses.

 

 

Bug fixes:

 

  • Sweep - Click at the end of the sweep automated capture
  • Spectrogram - Sum buttons should have the color of the sum curve
  • Magnitude spectrum / transfer function - setup parameters are selectively grayed out when they depend on the value of another parameter
  • General application robustness
 

 


Release - MiRA 25.07.50487

New features

  • Transfer function - Add magnitude threshold visualization
  • Sample grabber - Add a category selection box in the preferences, automatically chosen according to the DAW. It aims to get a better readability of the list.

Improvements

  • Sample grabber - If the speaker layout of the DAW is known, it is now automatically chosen.

Bug fixes

  • Core - Fix recurrent random crashes
  • Captures - Fix UI issue when editing a field and use mouse scroll
  • Main menu - Auto-pause threshold should be available for MIRA live and ultimate only
  • Max frequency value of several modules does not keep the max value when changing sample rate
  • SampleGrabber - AAX Windows - The displayed speaker layout is not the loaded one after closing the UI or reloading the session
  • System setup - Live microphone calibration capture is not correctly reloaded
  • System setup - Fix refresh issue after changing reference

Release - MiRA 25.04.50474

New features

  • Captures - Drag and drop captures between sessions
  • IO Setup - Add help content directly in IO setup panel to facilitate configuration regarding use case(s)
  • RMS / loudness metering - Add reset meters shortcut 'M'
  • Scopes - Customize scope name
  • Spectrogram - Add the possibility to use "Additional channels" in it

Improvements

  • Capture - Add a new action to create a new capture and stop the generator
  • Capture - Add a warning in the capture name popup when the capture is not filled out enough, and display the capture in red
  • Capture - Display current session captures at the top of the microphone / reference calibration target menu
  • IO setup - Don't hide "Device Input" and "Direct output" columns when there is no input/output device but just show them empty
  • Layout edition - Add confirmation dialog when removing one or all scope(s)/container(s)
  • Many optimisations - less CPU and memory consumption
  • Spatial spectrogram and Stereo vector scope - When mono, a label should be displayed to explain unavailability
  • Offset additional channels when modifying the input reference number of channels
  • RMS and Loudness - Update RMS and Loudness scopes' bottom labels according to preset name
  • Transfer function - Octave-band phase smoothing and UI
  • Transfer function - ART coherence sub-block computation
  • Transfer function - Added magnitude thresholding which halts buffer updates when input magnitude at a specific frequency falls below the specified threshold, helping the robustness of the capture. This works in tandem with the global auto-pause threshold.
  • Vector scope - Disable Fading control when Dynamic Fading is on for Vector Scope

Bugs fixes

  • Capture - Measurement capture name is not updated in the curve mouse hovering information after renaming it using the Capture scope name edit
  • Capture - Duplicating a capture does not always lead to the same TF curve
  • Capture - Ensure that the session is visible when the capture is set to visible
  • Capture - Fixed a crash when importing certain file formats
  • Capture - Offline edition of capture can be broken when using the "New capture" action after stopping the generator
  • Capture - Some live measurement sessions don't have a computed capture
