The record

Purpose: REW helps optimize listening-room, studio and home-theater acoustics, speaker and subwoofer placement, audio-chain performance and EQ.
Measurement: It measures frequency response and distortion using logarithmically swept sine signals and supports USB or analog measurement microphones and SPL meters.
Analysis tools: The software provides impulse and step responses, energy-time curves, spectral-decay plots, waterfalls, spectrograms, reverberation times, distortion, phase, group-delay and RTA views.
Signal generator: Its signal generator produces sine, square, sawtooth, dual-tone, triple-tone, multitone, tone-burst, CEA-2010, sweep, pink-noise and white-noise signals, with WAV export.
Equalization: REW automatically identifies response peaks, assigns EQ filters, optimizes filter parameters and can show predicted EQ waterfalls live.
Room simulator: The Room Simulator supports up to eight subwoofers.
Integrations: Equalizer entries include miniDSP, CamillaDSP, Hypex Input EQ, StormAudio, Dutch&Dutch 8c, Behringer, QSC, Crown, Xilica, Anti-Mode and other listed devices and processors.
Pro capture: The Pro upgrade captures multiple inputs simultaneously, supports per-input calibration, configurable weighting and SPL alignment, and averages captured channels.
STI: The Pro upgrade calculates Speech Transmission Index from impulse responses by the indirect method specified in IEC 60268-16:2020.
Platforms: Downloads are provided for Windows 7/8/10/11 and Vista/XP Pro x64, macOS 10.15–14, and Linux AMD64 or Java-runtime-based Linux.
Support: The maker provides comprehensive in-app and online help and directs users to the AV NIRVANA REW forum for assistance.
Privacy: The REW application and website do not collect user information, and downloads are free and anonymous; Pro-purchase email addresses are used only to deliver the upgrade code.
License: John Mulcahy licenses REW without charge for personal, educational and commercial use under a limited, non-exclusive, non-transferable license.
Notable limitation: The Pro upgrade is not required for multichannel outputs, which can be accessed through WASAPI exclusive or ASIO on Windows and Java drivers on macOS or Linux.
