Room EQ Wizard is a Java application for measuring room responses and correcting 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, spectrograms and energy-time curves; generating real time analyzer (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.
New in V5
Phase & Group Delay (measured, minimum, excess), Step Response and Spectrogram plots
Phase wrap/unwrap, minimum phase generation, IR delay calculation and adjustment
Separate windows for overlays, RTA and EQ functions
New algorithms for EQ adjustment offering exceptional tracking of target responses,
can be used over any frequency range
Waterfalls of predicted results of EQ can be viewed in the EQ panel and can update live as filter settings are adjusted
Support for QSC DSP-30 and Crown USM 810 parametric filters
"Modal" filter setting provided for parametric EQ filters to aid in correcting modal decay
V4 Features carried over
Still free!
Support for the Behringer Feedback Destroyer Pro models DSP1124P and FBQ2496 and the TMREQ
equaliser in the TAG McLaren AV32R DP and AV192R AV processors
Signal Generator offering sine waves, square waves, linear and logarithmic sine
sweeps, random pink noise (full range, speaker calibration, sub calibration and custom
filtered) and periodic pink and white noise
Measurement and impulse response import from text or WAV files
Frequency response measured using logarithmically swept sine signals for
fast, accurate measurements with approx 0.36Hz resolution across the measured range or
via real time analyzer with up to 1/48th octave resolution
Spectral decay plots, waterfalls and energy-time curves
Reverberation times derived in accordance with ISO 3382 in octave or one-third octave bands
with results for Early Decay time (EDT), T20, T30 and an optimal fit RT60 figure
The new Overlays window
The new RTA window
The new Spectrogram plot
Examples of the new EQ features in action
The original response
The effect of the automatic target match applied to the range 20 .. 100Hz
Before and after EQ with smoothing
The filters generated - note broad boost centred on 48Hz to balance the combined effect of the cuts
