Includes support and license for Dirac Live LE acoustic room correction technology including adjustments in the most difficult frequency region from 20Hz to 500Hz. Utilizing the included calibration microphone the Dirac software measures and calculates the DSP coefficients for a totally unique, pristine listening experience. As a software-based solution, Dirac Live for Studio is an interesting option for studios looking to improve their room acoustics with minimal costs and effort. Dirac Live for Studio The idea is to identify and solve problems with your room acoustics without the requirement for expensive absorbers or other room modifications. Dirac is a software tool for field or laboratory acoustics engineers. It measures impulse responses and calculates various room acoustical parameters, according to the ISO 3382 and IEC 60268-16 standards.

DIRAC is a valuable acoustics measurement tool for field and laboratory acoustics engineers, researchers and educational institutions. Users can compare the acoustics of one room with another, validate sound systems and perform scale model measurements. Based on the measurement and analysis of impulse responses, the tool supports a variety of measurement configurations.

Speech intelligibility measurements can be carried out in compliance with the IEC 60268-16 standard, for male and female voices, through an artificial mouth-directional loudspeaker sound source or through direct injection into a sound system, taking into account the impact of background noise.

Dirac Room Acoustics Software

In combination with Echo Speech Source Type 4720, speech intelligibility measurements can be performed quickly and easily. The Echo delivers a calibrated signal that is used by DIRAC to calculate different speech intelligibility parameters. The Echo/DIRAC combination also takes into account background noise levels.

Using OmniPower Sound Source Type 4292-L or OmniSource Loudspeaker Type 4295, the speech signal levels, impulse response and the background noise levels can all be acquired in a single pass. Plots of the STI vs. source-receiver distance can be created with a few mouse clicks.

With the minimum amount of measurements, DIRAC gives you L_p,A,S, L_p,A,S,4, D_2,S, STI, r_D and r_P.

Room Acoustics Software

REW is free software for room acoustic measurement, loudspeaker measurement and audio device measurement. The audio measurement and analysis features of REW help you optimise the acoustics of your listening room, studio or home theater and find the best locations for your speakers, subwoofers and listening position. It includes tools for generating audio test signals; measuring SPL and impedance; measuring frequency and impulse responses; measuring distortion; 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.
