Bad acoustics ruin great performances. Reverb Room RT60 tells you exactly how live or dead your space is — before you hang a single panel. Using the industry-standard Sabine formula, Reverb Room RT60 computes reverberation time (RT60) instantly from your room's dimensions and dominant surface material. Architects, sound engineers, home studio builders, and musicians use RT60 to design spaces that sound right. — KEY FEATURES — • Instant RT60 calculation — enter length, width, and height in meters, select a surface material, and the Sabine result appears immediately in large color-coded text. • 15-material catalog with real absorption coefficients — Carpet, Hardwood, Concrete, Brick, Glass, Drywall, Acoustic Foam, Fabric Curtain, Tile, Plaster, Wood Paneling, Cork, Mineral Wool, Cinder Block, and Marble. • Color-coded acoustic quality — results shift from blue (very dry) through green (ideal studio) and orange (lively) to red (very reverberant), so you read the acoustic character at a glance. • Volume and surface area displayed — see the computed m³ and m² values that feed the Sabine equation, so you understand the math behind the result. • Built-in RT60 reference guide — five labeled ranges from anechoic booth (under 0.3 s) to cathedral (over 2.0 s) appear as a plain-language description under every result. • Named room presets — save any room configuration with a custom name, edit dimensions or material later, and delete rooms you no longer need. • Comes pre-loaded with example rooms — Living Room, Studio Booth, Concert Hall, Home Theater, and Hardwood Study give you instant reference points. • Fully offline — no network connection, no account, no ads, no tracking. Your room data stays on your device. Whether you are treating a podcast booth, designing a rehearsal space, or simply curious about why your bathroom sounds like a cathedral, Reverb Room RT60 gives you the number you need in seconds. — Reverb Room RT60 PREMIUM — A Premium subscription unlocks unlimited saved room presets and the full 15-material absorption catalog, supporting continued offline, ad-free development of the app. Premium is offered as an auto-renewable subscription.
