Which one do you actually need?
Both check a room. The honest difference is what kind of question they answer — a whole-room average, or exactly what's happening seat by seat. Most people need Studio. A specific kind of room needs Pro.
The same room, through both lenses
A short illustration of the two kinds of answer: one figure for the whole room, or a figure for every seat. Scroll to watch one lens turn into the other.
- 1
One room, one number
The whole-room lens gives a single result for the room, shown as one calm wash of colour. It answers: does the room as a whole meet its target?
- 2
Split it into seats
- 3
Most seats are fine. One row is not
- 4
Follow the ray
- 5
Treat that surface, compare the seats
- 6
Take the controls
Whole room, one figure: 77 (illustrative score out of 100)
- On target, direct sound
- Below target, late reflection
| Echo Studio | Echo Pro | |
|---|---|---|
| Method | Statistical — one prediction for the whole room | Geometric ray-tracing — the room's real 3D shape, traced surface by surface |
| Result | One reverberation time and one speech-clarity figure per room | A figure per seat — the back row and the front row can genuinely differ |
| Finds | Whether the model predicts the room as a whole will reach its target | The specific reflection off the specific surface ruining one row's clarity |
| Ceiling shapes | Flat, sloped and vaulted ceilings are supported | The same shapes, traced as real geometry rather than a statistical approximation |
| Rooms & projects | Every project, every room, saved schemes and side-by-side comparisons | The same workflow layer as Studio — projects, saved rooms, a portfolio view, shared projects and revision history — built on Pro's ray-traced engine |
| Planning the fix | The main ways to reach target with the area needed — plus a two-material blend, a typical cost band for each route, and a live finish-swap to test changes before you commit | Reasons seat by seat rather than in treatment areas — compare two versions of a room seat by seat to see what a change actually does where people sit |
| What you hand over | A branded report with a plain-English write-up, a whole-building roll-up across a project, and a read-only link for your client | A design-submission dossier with method and uncertainty set out, an annotated seat map, and seat positions as a CAD (DXF) file |
| Hearing the room | — | Listen from any seat on headphones: that seat's own reflections, each arriving from its real direction |
| Noise that isn't echo | A noise-complaint check that tells you whether you're dealing with echo in the room or sound coming through a wall, plus a background-noise rating on the NC and NR curves from a measured spectrum | The same noise-complaint check and NC and NR rating as Studio |
| Best for | Classrooms, offices, restaurants, waiting rooms — most everyday rooms, checked fast | Any of those same rooms, plus auditoria, lecture halls and performance spaces — a more detailed, seat-by-seat view wherever it's worth having, not just where geometry forces it |
| Who tends to buy it | Designers, fit-out companies and venues checking rooms as they go | Architects and consultants who want a figure for every seat, from a single office through to a full auditorium |
| Price | £149/mo, per licence (initial three-month minimum £447, equivalent to £149 a month, then £149 a month until cancelled, GBP, tax included) | £299/mo, per licence (initial three-month minimum £897, equivalent to £299 a month, then £299 a month until cancelled, GBP, tax included) — or try one room first for £119, once |
you're checking classrooms, offices, restaurants, waiting rooms or similar everyday spaces; you want every project and every room on one plan with saved schemes to compare; or you're not sure yet and want the recommended option. Ordering opens soon, once our professional indemnity insurance is in place.
you design auditoria, lecture theatres or performance spaces where one row can sound noticeably worse than another; you need to show exactly which surface is causing a specific problem, not just that the room average misses target; or you're an architect who needs seat-level evidence, not a room-level estimate.
