How to use the script / Steps
Click the 'Upload calibration' button below to browse to the Audyssey calibration file (.ady)
generated by the MultEQ Editor (IOS/Android) app
When prompted, 'allow' multiple file download and 'save' the .zip (measurements) and .txt (target
curve) files on your computer
Start REW, go to the 'EQ' / 'House Curve'. Set DropDown 'Target Type' to 'None', than navigate to and select the 'Evo3_TargetCurve.txt' file
you've just saved.
Open the zip file and select ALL (keyboard shortcut: "CTRL+A" for Windows / "Command+A" for Mac) the
files in that folder
Left click on the selection and drag & drop them onto REW. Wait until all measurements are imported
and 'Optimize calibration' button is enabled
In REW left column you should be seeing your Audyssey speaker measurements with increasing index
numbers sorted in alphabetical order
Start REW's local API (application programming interface) server - 'Preferences' / 'API' / 'Start
server'
Keep REW at "SPL & Phase" tab and close all REW child windows during the optimization process for a
robust experience
If you intend to run optimization multiple times with the same calibration: 'Save all', 'Remove all'
and 'Open' saved measurements before each run
When all is set, click the 'Optimize calibration' button below and sit back and relax. Your home
cinema will be 'transformed' within minutes!
