Case Studies
The rest of the guide is organised by idea — a psychoacoustic principle, a spatialisation technique, a room behaviour, a workflow. This part is organised by job. Each chapter takes one concrete situation someone actually walks into — an album to mix, a tour to spatialise, a play to sound-design, a keynote to stage, a fixed-media concert to diffuse, a gallery piece to install — and reads it the same way every time:
- The brief. The situation in one paragraph: what is being made, for whom, in what space, under what constraints.
- Creative problematics and reflections. The decisions that belong to the author — composer, mixer, sound designer, director. What is space doing here, and why? These are taken first, before any equipment is chosen (see Artistic Practice).
- Technical problematics and reflections. The decisions that belong to the engineer. Layout, sweet spot, latency, calibration, deliverables, reliability — the constraints that will make or break the creative intent.
- Solutions — the general approach. What the field does about it, tool-agnostic: which technique fits, which workflow it draws on, what a sane signal chain looks like.
- Solutions — with RIPL. How the same problem is solved concretely in RIPL, DAM Audio's object-based spatial engine — and, just as important, where RIPL's design choices change which decisions you have to make.
- Pitfalls and a checklist. The failure modes specific to that job.
These chapters deliberately repeat and cross-link the conceptual parts rather than re-explaining them. When a case says "author as objects and let the renderer decode to the room," the why lives in object-based audio; the case only shows the when and the how.
A recurring architecture
One idea recurs across almost every case and is worth stating once. The durable way to build a spatial piece is to separate authoring from rendering: describe the work abstractly — sources at positions, trajectories, fields — and let a renderer map that description to whatever loudspeaker system is actually present. Author once, render to the stereo pair in the edit suite, the 32-speaker dome on opening night, the binaural stream for the archive. This is the object-based paradigm, and it is the single decision that lets a piece survive contact with a real, unpredictable venue. RIPL is built around exactly this separation, which is why it turns up in every chapter below.
The cases
- Capturing for Immersive — the recording side, and the claim that you do not need an "immersive" rig to work immersively: any microphone becomes a spatial object.
- Immersive Music Production & Post — an album, native immersive and re-rendered catalogue, delivered to Atmos and binaural; with a dedicated page per genre.
- Live Concert Spatialisation — a touring amplified show over an immersive PA, for a standing, moving crowd.
- Theatre & Live Performance — sound following actors on a stage, cue-driven, robust to a whole auditorium.
- Conference, Keynote & Corporate — intelligible speech first, immersive reveal second, hybrid stream third.
- Acousmatic & Fixed-Media Concert — diffusing a fixed work over a loudspeaker orchestra as live performance.
- Sound-Art Installation — a permanent or long-running gallery piece for a wandering public.
