Room EQ Wizard (REW) is a Java application for measuring room acoustics and countering room modal resonances. It includes tools for generating test signals, measuring frequency and impulse responses and automatically adjusting the settings of parametric equalisers to counter the effects of room modes. It also provides spectrum and Real Time Analyser displays for live monitoring of room response or live adjustment of EQ.
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.
