REW John Mulcahy

REW is a room acoustics measurement software designed for optimizing listening environments, loudspeaker performance, and audio device analysis. It provides tools for generating test signals, measuring SPL and impedance, analyzing frequency and impulse responses, and visualizing data through plots like waterfalls, spectrograms, and energy-time curves. The software also calculates reverberation times, Thiele-Small parameters, and modal resonances, enabling users to fine-tune speaker placement and acoustics.

Ideal for audiophiles, studio engineers, and home theater enthusiasts, REW helps users achieve optimal sound reproduction by identifying and correcting room mode effects. The Pro upgrade adds advanced features such as simultaneous multi-input measurements and rms averaging. It can be installed via winget for seamless integration into your workflow.
