Our verdict on Room EQ Wizard
Room EQ Wizard is desktop software for measuring and analyzing room, speaker, subwoofer, and audio-device performance. It is aimed at home-theater users, studio operators, audio engineers, and professional acoustic practitioners who need more than a basic spectrum view. The free core covers room and audio measurement, real-time analysis, offline measurement from imported sweep recordings, and analysis and equalizer tools. It runs on Windows, macOS, and Linux, with an API for application control and measurement access.
Its main strength is breadth. REW can measure frequency response and distortion with logarithmic swept-sine signals, while also providing impulse-response, phase, group-delay, spectral-decay, waterfall, spectrogram, energy-time, reverberation-time, and distortion views. The real-time analyzer supports up to 1/48-octave resolution, and the software includes SPL, equivalent sound-level, and sound-exposure-level measurement. Acoustic workflows extend to EDT, T20, T30, and RT60 reverberation calculations, parametric equalizer optimization, predicted EQ waterfalls, and room simulation supporting up to eight subwoofers.
The Free plan is substantial for single-input measurement and analysis. The Pro upgrade adds simultaneous multi-input capture, multi-input RTA, Speech Transmission Index calculation by the indirect method, and future pro features. That makes the paid tier more relevant to practitioners working with multi-input setups or speech-intelligibility analysis than to users focused on conventional room-response work. Choose REW if you want a wide set of measurement views, offline analysis, EQ optimization, and room simulation across major desktop platforms. Choose another tool if you need only a narrow, simple analyzer or require the multi-input and STI functions without a paid upgrade.
