Bagas31: Room EQ Wizard is a free program for measuring the acoustics of rooms, speaker systems and audio devices. With this program you can optimize the acoustics of your room, studio or home theater and find the best places to place your speakers, subwoofers and listening position. The program has the following features:
Measure frequency response and distortion using log-shifted sine waves for fast, accurate analysis of room acoustics and audio performance.
Measurement using an audio level meter, USB microphone or analogue measurement microphone.

Ability to use feedback or another speaker as a timing reference.
Offline measurement mode that allows you to generate responses from imported waveform records.
Frequency response and distortion measurements using step sine at 96 points per octave.
Real-time analyzer with resolution up to 1/48 octave.
Signal generator offering: sine waves (with the ability to add harmonics with level and phase control), square waves, two-tone signals, three-tone signals, multi-tone signals, pulse waves, CEA-2010 pulse waves, linear and logarithmic sine sweeps, random pink noise ( full range, speaker calibration, subwoofer calibration, CEA-2034, fractional octave and custom filtering), random white noise, periodic pink and white noise (full range, speaker calibration, subwoofer calibration, fractional octave and custom filtering).
Export signals to WAV files.
Sound level meter with full integration functions including equivalent sound level and sound exposure level; corrections are applied to the calibration of the microphone/level meter and sound card; A, C or Z curve weighing.
Two-channel oscilloscope with a math channel.
Spectral decay plots, waterfalls (Fourier and Burst Decay) and spectrograms (Fourier, Burst Decay and wavelet).
Impulse response, transient response and energy-time curves.
Reverberation times determined according to ISO 3382 in octave or one-third octave bands with results for early decay time (EDT), T20, T30 and optimal RT60.
RT60 Decay plot using frequency analysis to produce higher resolution decay data and narrower fractional octaves than is possible with classic RT60 analysis.
Parameters of clarity and certainty C50, C80 and D50 plus central time Ts.
The impulse response can be displayed using octave or one-third octave filters.
Measures harmonic and intermodulation distortion, including harmonic phase.
Phase and group delay (measured, minimum and excess).
Wrapping/unfolding phase.
Generation of the minimum phase response.
Impedance measurement including equivalent peak dissipation resistance (EPDR) plot, component model for inductance and capacitance measurements.
Calculation of Thiele-Small parameters from impedance measurements in a closed volume, with added mass or double added mass.
Calculation and correction of impulse response delay.
Detects and corrects clock frequency differences between input and output to different devices.
Arithmetic measurement functions, addition/subtraction/multiplication/division/combination of RMS average, vector average and dB average measurements for measurement sets.
