[Audison]ACCORDO - Automated System Tuning

[RobôAutoforum 9]

ACCORDO is a highly intuitive and powerful automated system tuning technology featuring adjustment of time delays levels and channel equalization.

ACCORDO generates test tones to measure the impulse responses of each component in the audio system. Then with proprietary processing techniques it synthesizes digital filters to compensate for the non-idealities in the speaker responses itself or in the acoustic response of the car cabin with ACCORDO non-idealities are compensated both in amplitude and in phase. Moreover ACCORDO identifies the time of arrival of each speaker and sets delays to re-align all the speaker contributions to the measurement position. Finally ACCORDO sets the levels of each channel in order to satisfy a desired response specified by the user.

To accomplish the channel equalization task ACCORDO adopts a proprietary synthesis technique for IIR filters with the ability to control both amplitude and phase for the frequency response of each component and with minimal processing latency.
