Ik kreeg zojuist bericht dat de final versie van Room EQ Wizard 5 uit is!
http://www.hometheatershack.com/roomeq/
Geweldig gratis programma om de akoestiek van je kamer te meten met eenvoudige middelen.
Vervolgens kan je met de resultaten aan de slag om de 'probleempunten' aan te pakken.
Zie ook eerdere threads over deze software!

Acoustic Measurement and Analysis
REW is a Java application for measuring 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.
New in REW V5
Phase & Group Delay (measured, minimum and excess)
Phase wrap/unwrap, minimum phase generation
Step Response and Spectrogram plots
Impedance measurement and Thiele-Small parameter calculation from impedance measurements
Impulse Response delay calculation and adjustment
Measurement arithmetic functions, add/subtract/multiply/divide/merge measurement
Separate windows for overlays, RTA and EQ functions
Sound level meter with full integrating functionality including equivalent sound level and sound exposure level; mic/meter and soundcard calibration corrections applied; A, C or Z weighting
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, Crown USM 810, Behringer DCX2496 and MiniDSP parametric filters
Resonance analysis to determine the frequencies and decay times of modal resonances with pole-zero plots of the response and any filters applied
"Modal" filter setting provided for parametric EQ filters to aid in correcting modal decay
Carried over from REW V4
Free!
Frequency response measured using logarithmically swept sine signals for fast, accurate measurements using either an SPL meter or measurement microphone
Real Time Analyser 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, impulse response can be displayed with octave or one-third octave filter applied
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 import from and export to text files
Impulse response import from WAV or AIFF files
Export impulse responses of measurement or filter settings to WAV files with 16, 24 or 32-bit resolution
Automatic identification of peaks in the response, automatic assignment of filters to peaks and optimisation of filter parameters to counter the peaks
