What's Inside

25 features — Pro adds 11

Every Orbit edition shares the audio engine and the spatial QC suite. Pro layers on the finishing tools — sessions, video, IAMF / AXML export, multi-track playback, and the bigger workflow surfaces.

Pro Sessions

Save Your Place,
In One File

Save the full state of your work as an .orbsession file — loaded ADM or IAMF (Eclipsa), video clips, markers, loop regions, layout, the lot. Open it tomorrow, on another Mac, in another studio, and pick up exactly where you left off.

A .orbsession file as it appears in Finder — single document, 2.04 GB, kind 'Orbit Session'
Show package contents
The .orbsession bundle expanded — .orbit-lock, AudioFiles folder, session.json, session.json.bak, VideoSources, Waveforms

Self-contained

Audio, video, markers, layout, settings — packaged into a single portable file.

Sharable

Hand a session to a colleague, open it on the studio iMac, archive for next year — the state goes with it.

Resumable

Loop region, scrub position, marker selections — every UI state restored when you reopen.

Pro Video

Picture & Sound,
In One Timeline

Sync video to your ADM masters, then cut, trim, and arrange clips on a multi-clip video timeline with scrub, loop, and snap. Export an IAMF + MP4 bundle ready for delivery to platforms that accept the format — ideal for creators working across sound and picture.

Orbit Pro 1.5 video editor — clip bin, video preview, scene view and timeline
Pro Export

Quite possibly the world's most
advanced IAMF export.

Take your ADM BWF masters straight to IAMF / Eclipsa — the immersive standard powering YouTube's Eclipsa Audio. Shape every signal path through a full routing graph, choose your codec, profile and render targets in one window, and hear exactly how it'll sound before you commit. Nothing else works quite like it.

Orbit Pro 1.5 IAMF export — auto-route presets, encoding settings, the routing graph and live render stats

Codecs

Opus, AAC-LC, FLAC, LPCM — pick the trade-off that fits your delivery target.

Profiles

Simple, Base, or Base Enhanced — spec-compliant IAMF for every platform tier.

Render Targets

Stereo, 7.1.4, binaural — render the targets each platform needs, auditioned before you commit.

Pro Export · ADM

AXML, Standalone
For Round-Trips

Extract the structural metadata of any ADM master as a standalone AXML file — the same XML that lives inside a BWF, pulled out so you can read it. Brilliant for confirming the file actually got encoded the way you expected, and a fantastic teaching tool for showing people exactly what makes an ADM tick.

Exported AXML opened in VS Code showing the typeLabel, organisationDetails, audioFormatExtended, and audioObject elements

Shown opened in VS Code · A built-in AXML viewer is coming soon

Spec-compliant XML

Pure ITU-R BS.2076 AXML — exactly the structure that lives inside the BWF, nothing added, nothing lost.

Verify encodes

Confirm a deliverable actually got the channel layout, object count, and metadata it was supposed to carry — before it ships.

Teaching tool

Show students, clients, or new engineers exactly what makes an ADM tick — every audioObject, every block, every reference, plain XML.

Pro Workflow

Tight Loops,
Deep Zoom

Drop a loop region around any section and let it cycle while you tweak parameters or check a difficult passage in context. Zoom deep into the waveform to isolate transients, debug crossovers, or scrub fades sample-accurately.

Loop region with start/end timecodes highlighted on the timeline
Pro Review

Notes That Travel
With The Mix

Drop markers anywhere on the session, link them to specific objects, and add comments. Each marker carries the time, the linked objects, and your note. Export the full marker map as a shareable PDF for stakeholders or as CSV for issue trackers and spreadsheets — review without ever opening Orbit.

Pro Playback

One Mix Down,
One Click

Queue multiple ADM and IAMF tracks and let Orbit roll through back-to-back. Auto-advance moves to the next track when one finishes — perfect for album reviews, batch QC, or letting clients hear the whole shortlist without you driving the transport.

Track playlist sidebar showing queued ADM and IAMF files, each with a format badge and waveform preview

Queueable

Drop ADM and IAMF tracks into the playlist, drag to reorder, save the queue with the session.

Auto-advance

Track ends, the next one starts. Or pause between for client check-ins. Toggle per session.

Mix-down friendly

Album QC in one sitting — loudness check the whole record, then the singles, without re-loading.

Pro View

Every Track,
Side By Side

Show every track's waveform at once — beds and objects stacked vertically — so you can scan an entire session in a single view. Find the one track with a level issue, the one object with a silent gap, without drilling through each one individually.

The Timeline view in Orbit Pro showing every bed and object as a stacked waveform timeline

Stacked

Every bed and object on its own row, time-aligned, time-locked to the master scrubber.

Scannable

Spot anomalies — silent gaps, level mismatches, dropped objects — in seconds, not minutes.

Pro Inspection

One Track,
Every Trajectory

Drill into any track to see its waveform alongside the X / Y / Z position trajectories — the spatial movement of an object visualised against the audio that drives it. Catch trajectories that don't match the audio energy, find dropped automation points, sanity-check spatial design before render.

Object inspection in the timeline — a track's waveform above its X, Y, Z, gain and width automation lanes

Pro Calibration

Match Your Room,
Not The Spec

Set Orbit to the physical positions of your monitors — wherever the speakers actually sit, the binaural and stereo fold-down compensate so what you hear matches what would play back on a perfect rig. Test each output with the built-in pink-noise generator, from 9.1.6 right down to Quad.

Physical speaker configuration — output layouts from 9.1.6 to Quad with a top-down view and per-speaker test

Saveable presets arrive in Orbit 1.5.1.

Pro Speaker Layout · New in 1.5.2

Solo, Mute & Group,
Right On The Speakers

A speaker layout view across the whole multichannel output system. Click any speaker in the top-down, side or 3D view to solo it — or build custom groups of solos and mutes that follow you across every view. A simple idea with a lot of power for testing, and it works with any layout up to 64 channels via OSLS.

The shared baseline.

Every Pro licence inherits these — and Standard ships with them at the lower tier. Same audio engine, same fidelity, same QC suite.

01 — Visualization

02 — Ambisonics

Scene-Based Audio,
Fully Supported

Orbit 1.4 ships with first, second, and third order Ambisonics — in both ADM BWF and IAMF (Eclipsa). Sound fields decode alongside your beds and objects, rendered through the same 7.1.4 speaker bus and binaural pipeline as everything else.

09 — Headphone EQ

Mix On Anything,
Hear It Honestly

Most of us don't mix on flat headphones — we mix on the cans we own. Orbit ships with a Headphone EQ panel that flattens your headphones against a known target so what you hear is closer to what's actually in the file. Curated AutoEq-derived presets for the usual suspects (HD 650, HD 800 S, DT 770 Pro, LCD-X, AirPods Max, MDR-7506, and plenty more), a five-band tone tilt for taste, and a live response graph that draws the lot.

Orbit Headphone EQ panel showing compensation preset, five-band tone controls, and the live response graph

Compensation

Parametric correction curves derived from AutoEq, plus an automatic preamp so the total stays below unity gain. Reference (Harman 2018) for monitoring, or Music for a warmer tilt.

Tone

Five knobs — Bass, Lo-Mid, Mid, Hi-Mid, Treble — sit on top of compensation. Nudge for taste without touching the underlying curve. Double-click to reset.

Live Response

The graph at the bottom of the panel draws preset, tone, and combined curves in real time as you adjust — you see exactly what's being applied.
