Echo Studio Versus Pro Technical Differences

What actually separates Echo Studio from Echo Pro -- whole-room statistical prediction versus seat-by-seat geometric ray-tracing. Studio runs a single Sabine/Eyring whole-room average and handles flat, sloped or vaulted ceilings -- aimed at designers, fit-out companies and venues. Pro runs full geometric ray-tracing, surface by surface and seat by seat -- aimed at architects and consultants working on auditoria, lecture halls and performance spaces. States the real live pricing: Studio at £149/month (or £447 for the first 3 months) with a 3-month minimum term; Pro, still in development and waitlist-only, at £299/month (or £897 for the first 3 months).
