IRIS 1.4 Docs

IRIS is a room acoustics measurement system developed by Marshall Day Acoustics in New Zealand. It was released at the beginning of 2014 as a fully integrated hardware and software system for making 3D impulse response measurements. It is now also available in a software-only form.


If this is your first time making measurements with IRIS, please start with Conduct a Measurement, followed by the IRIS Plot section.


We’ve prepared a helpful Measurement Checklist to run through before and during conducting measurements on site.
