Plays a stimulus signal in an enclosed space, records it through a microphone, then compares the two sounds to calculate acoustical parameters such as reverberation time, standard deviation, min-max, etc.

Dirac is a sophisticated tool to calculate a very wide range of acoustical parameters from impulse response measurements of an enclosure. Through many years of development and customer feedback, Dirac has grown to support many different applications. Due to its user friendly interface it is suitable for field measurements, but it also contains many advanced features that make it useful in a laboratory or research setting.

To capture an impulse response, a stimulus signal is generated by Dirac or an external source. This stimulus signal is played in the enclosure through a sound source, and recorded through a microphone. Dirac then deconvolves the recorded response with the original stimulus to arrive at the impulse response.
