Surround and Immersive

Turn a stereo master into surround: 5.1, 7.1, quad, height beds up to 9.1.6, or ambisonics. All of them still fold back down.

Turn a stereo master into surround, and fold it back down safely.

Take a finished stereo mix and place it into a surround or immersive layout: 5.1, 7.1, quad, height beds up to 9.1.6, or ambisonics for VR and 360 video.

Every layout still folds back down to stereo cleanly, so you are never trading your stereo master away for the surround one.

Key points

  • Layouts from quad and 5.1 through 7.1.4 and 9.1.6, plus ambisonics.
  • Centre level, surround level and LFE crossover are all under your control.
  • A headphone check lets you audition the result binaurally.
  • 2 tokens per run.

What it is good for

  • Film and television. Deliver a 5.1 or 7.1 music bed against picture.
  • Immersive releases. Produce a height-bed version for platforms that support it.
  • VR and 360 video. Ambisonics is the format these platforms expect.
  • Installations and live. Multi-speaker playback in a venue or exhibition.

Fold-down matters more than width

A surround mix that sounds spectacular in a treated room and collapses when it is folded to stereo is not finished. Most listeners will hear the fold-down, not the full layout.

Every layout here is built to sum back to a coherent stereo image, and the headphone check lets you hear the binaural rendering before you commit.

What it costs

Surround and Immersive costs 2 tokens per run. Tokens work across every tool, so one balance covers everything here. A Studio subscription at $19.99 a month includes a monthly allowance and the full engine alongside it.

Common questions

Is this Dolby Atmos?

No. This produces channel-based surround and ambisonic formats. For a true Atmos deliverable with audio objects and ADM metadata, use the AI Dolby Atmos Mixer.

Which layout should I pick?

5.1 remains the most widely supported for film and television. 7.1.4 and 9.1.6 add height for immersive delivery. Ambisonics is the answer for VR and 360 video.

Will it damage my stereo master?

No. Your original is untouched; the surround version is a new deliverable alongside it.

  • AI Dolby Atmos Mixer (12 tokens) — Turn a stereo mix into an immersive master: a 7.1.2 bed, placed audio objects and ADM metadata, ready for the Dolby Atmos Renderer.
  • Stereo Widener (1 token) — Width that survives a mono fold-down.
  • Loudness Meter (free) — Integrated LUFS, loudness range, true peak and RMS, with a plain verdict on headroom and streaming loudness.
