REW (Room EQ Wizard) is a Java application for measuring room responses and countering room modal resonances. It includes tools for generating test signals; measuring SPL; measuring frequency and impulse responses; generating phase, group delay and spectral decay plots, waterfalls and energy-time curves; generating real time analyser (RTA) plots; calculating reverberation times; displaying equaliser responses and automatically adjusting the settings of parametric equalisers to counter the effects of room modes and adjust responses to match a target.
REW uses a logarithmically swept sine signal for its measurements. This is much faster than manual measurements, more accurate, less likely to suffer from clipping at resonances, less sensitive to system non-linearity than MLS and allows the impulse response of the room to be determined, which in turn is the basis for many additional features. When using the Real Time Analyser displays REW can generate Pink Periodic Noise sequences for much better visibility of low frequency behaviour than obtained using random Pink Noise without the need for lengthy averaging.
