What it does

MiRA Session is the 2-channel edition of FLUX::'s MiRA analysis software, combining spectrum analysis, loudness and stereo metering in one workspace. Its tagline is "Get your mix RIGHT."

Spectrum analysis: an RTA (spectrum magnitude) with manual, auto, compressed and compressed auto modes, plus a spectrogram, both with real-time statistics.
Level metering: RMS, Peak and True Peak meters.
Loudness: LUFS metering with EBU R128 and ITU-1770 modes and presets for streaming platforms.
Stereo field: a stereo vector scope and the Nebula spatial spectrogram, which shows where frequencies sit across the stereo field.
Wave scope: a waveform view alongside the other scopes.
Layouts: fully customisable workspaces, a Daylight Mode UI and an I/O setup page.
Sample Grabber: a plugin that pushes audio from DAW inserts into MiRA, which also talks to FLUX:: SPAT Revolution.

The current version is 26.04. Session is limited to 2 channels at up to 96 kHz; the subscription-only Studio, Live and Ultimate editions add up to 24 channels, immersive tools, 3D Nebula and system calibration. A trial is available on request.

When to use it

MiRA Session is for engineers who want one analysis window covering spectrum, loudness and stereo image. Compared with Insight 2, it covers similar ground in one window and adds the Nebula spatial spectrogram. It does far more than Youlean Loudness Meter 2, which is cheaper and enough if you only need LUFS readings. Against the free SPAN, it adds loudness, true peak and stereo scopes in customisable layouts.

Best for: checking spectrum, loudness and stereo image on stereo mixes and masters, and podcast loudness compliance.
Genres: any style.
Look elsewhere if: you only need a loudness meter (Youlean Loudness Meter 2), a free spectrum analyzer (SPAN), or surround and Atmos metering (a higher MiRA edition).

What producers say

Early press coverage is positive, though most of it covers the larger MiRA editions.

proaudio.tech (2025, testing mainly MiRA Studio) called it "very well-thought out and practical" at "quite acceptable prices", noting CPU use of at most 4% and praising the Nebula scope and flexible layouts.
Criticisms: the same review wanted easier channel format selection; its other complaints concerned multichannel features Session doesn't include.
