MiRA Live by FLUX:: is a real-time audio analysis and metering tool for live mixing and system tuning, offering customizable workspaces, advanced microphone captures, and a unique spatial spectrogram.
Purpose and Core Function
MiRA Live is a real-time audio analysis and metering application designed for live sound engineers and system tuners. It provides continuous, instant visual control over critical mix parameters, including sound level readings with Leq output metering and a live magnitude spectrum. The tool supports customizable workspaces tailored to specific needs, along with pre-defined layouts for show conduct, allowing operators to focus on essential information during a performance.
A standout feature is the FLUX:: Nebula spatial spectrogram, which merges the capabilities of a spectrum analyzer and a vector scope. This unique visualizer assists in making critical localization decisions for the mix. MiRA Live extends Nebula support to monitor the output of SPAT Revolution or other immersive processors, making it a versatile tool for both conventional and spatial audio workflows.
Key Capabilities and Analysis Tools
MiRA Live includes a suite of dependable tools for mastering the technical fundamentals of audio system calibration. Users can access Transfer Function readings, Magnitude, Phase, and Coherence traces, as well as live impulse response. For delay computation, a real-time finder function helps identify timing issues quickly. The Adaptative Resolution Transform (ART) mode mitigates phase computation inaccuracies compared to standard FFT methods, ensuring more reliable measurements.
The application supports capture, analysis, and offline recomputation of measurements, allowing engineers to revisit and refine their analysis after a session. Users can analyze with multiple microphones, capturing live or averaging trace snapshots, and can also import impulse response (IR) files for further examination. This flexibility supports both real-time tuning and post-event forensic analysis.
Workflow and Show Management
MiRA Live features advanced session management for system measure captures, with offline recompute support. This allows engineers to efficiently organize and process multiple measurements during a tuning session. The application supports up to 23 measurement microphones, each with real-time delay finder and averaging capabilities, making it suitable for complex multi-microphone setups.
A new microphone pairing mode increases capture coherence between floor and ear level microphones, which is particularly useful for accurately capturing the sound field as experienced by the audience. For live shows, a dedicated layout lets you choose your SPL/Leq microphone and define up to three independent SPL/Leq measurement settings, ensuring that level monitoring is tailored to different zones or requirements during a performance.
Practical Applications and Offline Analysis
In practical use, MiRA Live streamlines system tuning and calibration. Engineers can use the transfer function and impulse response tools to align speakers, verify phase coherence, and set delay times for distributed systems. The spatial spectrogram is ideal for immersive installations where localization accuracy is paramount, such as in theater, live events, or installations using SPAT Revolution.
The offline recompute feature is beneficial for post-event analysis, allowing engineers to review captured data and adjust their conclusions without needing to be on site. The ability to import IR files extends its utility for analyzing third-party measurements. This combination of real-time and offline capabilities makes MiRA Live a comprehensive tool for both live mixing and detailed system analysis.
