Introduction

In the realm of acoustics, understanding the behavior of sound within an enclosed space is crucial for various applications, including audio engineering, architecture, and research. Dirac, a sophisticated tool, has been designed to calculate a wide range of acoustical parameters from impulse response measurements of an enclosure. With its user-friendly interface and advanced features, Dirac has become an essential tool for both field measurements and laboratory research.

What is Dirac?

Dirac is a device assistant that plays a stimulus signal in an enclosed space, records it through a microphone, and then compares the two sounds to calculate acoustical parameters such as reverberation time, standard deviation, min-max, and more. This innovative tool has been developed over many years, with customer feedback playing a significant role in shaping its features and functionality.

How Does Dirac Work?

The process of capturing an impulse response using Dirac involves several steps:

Stimulus Signal Generation: Dirac generates a stimulus signal or uses an external source to create one. This signal is then played in the enclosure through a sound source.
Recording: The stimulus signal is recorded through a microphone, capturing the response of the enclosure.
Deconvolution: Dirac deconvolves the recorded response with the original stimulus signal to arrive at the impulse response.
