3.4.1 Listening environment
The Measurements tab presents three different listening environments as a visual guide to positioning the
microphone for each of the nine measurements: Chair, for a single listening seat; Sofa, for multiple listening
seats; and Auditorium, for a large dedicated home theater or larger venue with staggered seating. Use the icons
at the left of the screen to select the listening environment.
The center of the screen contains a pictorial representation of the selected listening environment, with dots
marking the recommended microphone locations. Completed measurements are shown in green, while the next
measurement to be done is highlighted in yellow and has a red arrow marker pointing to it. A drop -down menu
underneath selects three different views, which should be used to help you place the microphone in a suitable
location.
While the visual guide indicates a suitable set of microphone locations, these locations can be varied to suit
individual circumstances. It is, however, imperative that the first measurement is taken in the center of the
listening area, as this measurement is used to set the levels and delays of each channel. The subsequent eight
measurements should be well spread out over the entire listening area so that Dirac Live can acquire a good set
of measurements that capture the acoustic behavior of the room. Placing all microphone locations too close to
each other may result in “over-correction” that will sound dry and dull.
