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
FLUX:: MiRA 25.07.50487
New features
Transfer function - Add magnitude threshold visualization
SampleGrabber - Add a category selection box in the preferences, which is automatically chosen according to the DAW. This improves the readability of the list.
Improvements
SampleGrabber - If the speaker layout of the DAW is known, it will now automatically be chosen.
Bug fixes
Core - Fixed various recurrent random crashes
Captures - Fixed UI issue when editing a field and using mouse scroll

FLUX:: MiRA 25.04.50474
New features

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 optimizations - 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 threshold 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
