Dirac Dimensions – More technical information
Tailored for automotive OEMs
Packaged in software together with a purpose-made microphone array, Dirac Dimensions uses a powerful work process tailored specially for automotive OEMs, and offers experienced audio engineers more flexibility and control to achieve the best possible result in a limited time.
- A large number of measurements for each speaker are carried out in a special-purpose measurement array.
- A reference room and reference speaker layout is designed in the Dirac Dimensions software. Speaker placements, wall characteristics, and other parameters can be adjusted.
- Based on the reference design, the software simulates impulse responses corresponding to the various measurement positions in the reference room.
- A filter matrix is then optimized based on the measured response and the desired responses derived in step 3 in order to create the best possible fit to the reference sound field.
