Room EQ Wizard
Room EQ Wizard (REW) is measurement and analysis software for working on listening-room, studio, and home-theater acoustics, speaker and subwoofer placement, audio-chain performance, and EQ. It measures frequency response and distortion with logarithmic swept sine signals and supports USB or analog measurement microphones and SPL meters. Its views include impulse and step responses, energy-time curves, spectral decay, waterfalls, spectrograms, reverberation times, distortion, phase, group delay, and real-time analysis. REW's signal generator produces tones, sweeps, bursts, and noise, among other signal types, with WAV export. Its EQ tools identify response peaks, assign filters, optimize filter parameters, and display predicted EQ waterfalls live. The Room Simulator supports up to eight subwoofers. The free plan includes single-channel capture, measurement, real-time analysis, and EQ tools. REW runs on Linux, macOS, and Windows.
