Acoustic Measurement and Analysis

REW is a Java application for measuring room acoustics and analysing room and loudspeaker responses.
It includes tools for generating test signals:
  • measuring SPL and impedance
  • measuring frequency and impulse responses
  • generating phase, group delay and spectral decay plots, waterfalls, spectrograms and energy-time curves
  • generating real time analyser (RTA) plots
  • calculating reverberation times
  • calculating Thiele-Small parameters
  • determining the frequencies and decay times of modal resonances
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 curve.


Highly recommended Acoustic Measurement and Analysis Software!
Free registration is required.
