Reverberation Time API
Room-acoustics reverberation-time maths as an API, computed locally and deterministically. The sabine endpoint computes the reverberation time of a room — the RT60, the time for the sound to decay by 60 dB — from the Sabine formula RT60 = 0.161·V/A, where V is the room volume and A the total absorption in metric sabins; you can give the absorption directly, or as a surface area times an average absorption coefficient, and it also solves the absorption you would need to hit a target reverberation time. The eyring endpoint uses the Eyring-Norris formula RT60 = 0.161·V/(−S·ln(1−ᾱ)), which is more accurate than Sabine for absorbent rooms with a high average coefficient, and reports both for comparison. The absorption endpoint builds the absorption budget from a list of surfaces, each with its area and absorption coefficient, returning the total and average absorption and the resulting Sabine RT60, plus the extra absorption needed to reach a target. Everything is computed locally and deterministically, so it is instant and private. Ideal for acoustic-design, studio, classroom and home-theatre tools, room-treatment planning and building-acoustics apps, and audio-engineering education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is room reverberation time; for decibel conversion and combining sound levels use a sound-level API.
