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.
USE SCENARIOS
The sub integration was included in the Room Perfect system from the beginning, it is a hardware and software solution. Big board, as large as some Class D amps, with circuitry. The Room Perfect system has evolved, was 96k/24. Has been 192K/24 for a while. Processing power on board has been increased. Klipsch, inventor, acoustics pioneer and maverick, founded Klipsch Audio with the sole purpose of bringing the power, detail and emotion of the live music experience into his living room. In equalization circles, Dirac Live has been making waves recently with their Dirac Live Room Correction software. It h as already been integrated into high-end processors such as Datasat and Theta Digital, as well as luxury automotive sound systems from Rolls Royce, Bentley, and BMW.

Dirac Room Acoustics Software
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.
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 Lp,A,S, Lp,A,S,4, D2,S, STI, rD and rP.
