How to use the script / Steps

1. Click the 'Upload calibration' button below to browse to the Audyssey calibration file (.ady) generated by the MultEQ Editor app (iOS/Android)

2. When prompted, 'allow' multiple file download and 'save' the .zip (measurements) and .txt (target curve) files on your computer
3. Start REW, go to the 'EQ' / 'House Curve'. Set DropDown 'Target Type' to 'None', then navigate to and select the 'Evo3_TargetCurve.txt' file you've just saved.
4. Open the zip file and select ALL (keyboard shortcut: "CTRL+A" for Windows / "Command+A" for Mac) the files in that folder
5. Left click on the selection and drag & drop them onto REW. Wait until all measurements are imported and 'Optimize calibration' button is enabled

7. Start REW's local API (application programming interface) server - 'Preferences' / 'API' / 'Start server'
8. Keep REW at "SPL & Phase" tab and close all REW child windows during the optimization process for a robust experience
9. If you intend to run optimization multiple times with the same calibration: 'Save all', 'Remove all' and 'Open' saved measurements before each run
10. When all is set, click the 'Optimize calibration' button below and sit back and relax. Your home cinema will be 'transformed' within minutes!
