Pick Up Where Treatment Left Off.
Speaker calibration picks up where treatment leaves off: taming the low-frequency room problems your panels couldn’t, and time-aligning your speakers so they stop fighting each other and cancelling out.
Omnissiah measures your speakers with a microphone at the seat, then its optimiser tries thousands of corrections and keeps the best one. Toggle before and after, then send it to your Tantrum hardware or run it live through the audio interface you already own.

Sonarworks SoundID and IK Multimedia ARC measure from a captured sweep and skip phase alignment entirely. Omnissiah adds realtime measurement, phase and time alignment, and native DSP control: features that otherwise cost four figures in hardware like Trinnov.

Updates Log
V0.1.2
- Backup & restore: save every connected device's settings plus calibrations, target curve and loopback correction to a single file, and restore them later
- Linked outputs: choose per control (Mute, Gain, Delay, Polarity, EQ, Crossover) whether a link shares it or keeps each independent
- Custom target curves and a redesigned target picker with preset cards; new 'Tantrum Flat' house curve is now the default
- Crossover-aware room correction detects your crossover and rolls each speaker off there, fixing bass doubling
- Added 'Align Only' mode to align time, level and polarity without running a full room correction
- Measurement latency is now stable across runs (~19 ms drift reduced to well under 1 ms) by timing off the audio hardware clock
- Improved room correction: corrects treble roll-off, addresses room modes down to 20 Hz, and caps combined boost across stacked filters
- Reworked results page with per-channel diagnostics, a setup-assumptions summary, target reference line and a Before/After toggle
- Quick Measurement Settings let you set mic positions per speaker without leaving the calibration setup page
- Added room-correction bypass to A/B corrected vs uncorrected signal, plus Boost/Cut Trust confidence controls
- Added mono speaker support, and many fixes to alignment determinism, linked-output calibration and measurement stability
V0.1.1
- Added a guided Quick Measurement flow with on-screen mic movement diagram
- Calibrations are now saved and persist between sessions
- Reworked calibration results page with improved before/after rendering and measurement position info
- Added loopback room correction from quick align and from a manual measurement
- Added audio engine settings with selectable default sample rate
- Improved room correction quality and optimisation speed
- Fixed audio configuration crash on config load and sample rate bugs in sliding windows
- Firmware updates and Really Mean Sub v0.0.7
BETA v0.0.9
- Improved measurement stability
- Improved calibration workflow and results
- Fixed bug where calibration could fail to complete
- Added 5.1 calibration support
- Added device control crossover support
- Added measurement snapshot exporting
- Added ±24dB normalised measurement view
- Really Mean Sub firmware update to v0.0.5
BETA v0.0.8
- You can now apply the results of Quick Align calibration directly to DSP
- Improved calibration results page with before and after graphs
- Calibration measurements now use signal to noise ratio in spectra to determine the optimal measurement level threshold, instead of taking a noise reading pre-measurement
- Improved Quick Align workflow
BETA v0.0.7
- Improved measurement responsiveness
- Improved fast averaging and measurement stability
- You can now reset measurement gain and delay offsets
- You can now edit measurement snapshot names and colours
- Added Quick Align to side bar
v0.0.6
- Improved measurement stability
- Mouse Over tooltips for measurement values
- Added jitter detection and excess jitter warnings
