The app analyses how long sound bounces around and gives you concrete recommendations for acoustic treatment. Measurement methods: – Clap measurement: clap your hands and the app analyses the room automatically – ESS measurement (exponential sweep sine): professional measurement with external speaker and microphone – Interrupted noise measurement (ISO 3382): for detailed T20/T30 values per octave band AR room measurement: Measure room dimensions using augmented reality directly in the app – no tape measure needed. Acoustic analysis: Get a clear report with reverberation values per frequency band (125–4000 Hz) and comparison against guidelines for your room type. Request a treatment proposal: Submit your measurement results and room dimensions to receive a cost estimate for acoustic products from Absoflex and ACQwool. The app is free to use.
