REW is a free tool for room acoustics. The application will be perfect for people who intend to open a recording studio. However, this does not mean that REW is aimed exclusively at professionals, as the program can also be used in situations where we want to ensure the best possible sound quality in our home theater to find out where to place speakers or subwoofers.

REW allows you to generate test audio signals, offers the possibility of measuring SPL and more. The tool can also generate various charts (especially waterfall charts), as well as calculate reverberation time and Thiele-Small parameters. Remember to set the USB microphone (UMIK-1 miniDSP is recommended) before starting the tests, and while using the REW application, set the measurement length to the longest possible length.
