What's New in v1.2.0
Accurate loudness metering
Loudness and true peak metering has been overhauled for QC accuracy. The BS.1770-4 loudness formula has been corrected (fixing a ~3 dB error on multichannel content), proper 7.1.4 surround channel weighting has been added, and true peak detection now uses ITU-R BS.1770-4 compliant 4x oversampled interpolation. Meters now read pre-gain, so readings are independent of the monitoring volume.
Accuracy is validated against ffmpeg's ebur128 filter — all LUFS measurements agree within 0.05 dB across test signals.
A binaural rendering distortion has also been fixed.
PDF loudness report
The advanced PDF export now includes a Measured Loudness section with Orbit's own offline analysis: integrated LUFS, true peak (excl. and incl. LFE), loudness range (LRA), max momentary, and max short-term — plus a time-series graph showing momentary and short-term loudness over the full duration of the file.
True peak LFE toggle
You can now choose whether the LFE channel is included in the True Peak reading. A toggle below the True Peak meter lets you switch between excl. LFE (the BS.1770-4 standard default) and incl. LFE for a full-range measurement across all channels.
Faster file loading
File loading is significantly faster thanks to parallel I/O during waveform scanning. VBAP waveform rendering is now deferred until you actually switch to VBAP mode, cutting initial load time.
Enhanced loading screen
The loading screen now shows detailed progress: file metadata (channels, sample rate, duration, bit depth), a live waveform scan animation, and real-time throughput stats. A progress overlay also appears when generating VBAP waveforms on demand.
Output routing presets
The output routing window now tracks which preset is active with a label in the presets bar. Save overwrites the active preset (with a confirmation prompt), and Save As lets you create a new preset by name. Your active preset is remembered across app launches.
When loading a preset, Orbit checks whether the saved audio device is still available. If it isn't, a sheet shows which device is missing and lets you pick an alternative — with a warning if the replacement has fewer output channels than the original.
Activity grid in standard layout
The activity grid (showing beds and objects as animated hexagonal tiles) is now visible in both Standard and Split layout modes.
Improved head tracking responsiveness
Camera-based head tracking is now significantly more responsive. End-to-end camera tracking latency has been reduced by roughly half (~160 ms to ~80 ms). The UI visualiser also updates at 40 Hz (up from 20 Hz) so the 3D scene keeps pace with head movements. AirPods tracking smoothing has also been tightened for snappier response.
