AKM Launches AK7709VQ Multicore DSP for Automotive Applications

Asahi Kasei Microdevices (AKM) launched a new multicore digital signal processor (DSP) that is an integral part of the Velvet Sound for Cars brand announced in May 2023. A combined suite of high-quality audio ICs, software algorithms, and tuning intended to enable a new generation of in-vehicle sound design and luxury immersive audio experiences. AKM also unveiled an advanced concept, a car sound board integrated with the AK4499EX flagship Velvet Sound Verita DAC for the ultimate audio quality.

Asahi Kasei Microdevices (AKM) and Silentium have signed a license agreement to develop engine order cancellation (EOC) solutions that reduce the impact of engine noise in the car cabin. By incorporating Silentium's proven EOC software, combined with AKM semiconductor and sensor technologies, vehicle manufacturers will be able to quickly implement systems that improve fuel efficiency by reducing reliance on heavy noise dampening materials.

DSP Concepts announced a collaboration with the Automotive Systems Division of Bose Corporation to bring the company’s Active Sound Management (ASM) solutions into Audio Weaver. Engineers from DSP Concepts and Bose have completed work demonstrating the effectiveness of one of those ASM solutions – Bose QuietComfort Road Noise Control (RNC) – within the Audio Weaver environment, adding to the platform’s library of nearly 500 market-proven modules available to developers through a drag-and-drop graphical interface.

We probably listen to more music and podcasts in our cars than anywhere else. Which means this is where we’re pushing the boundaries of audio experience — less noise, personalized sound zones, and control. And we’re more aware of the safety implications, not distracting or tiring the driver. This article was published in audioXpress, June 2020.

The automotive industry continues to evolve. A new survey by Asahi Kasei Europe shows that changing mobility behavior and the growing autonomy of cars will profoundly impact the user’s driving experience. Automotive interior features are on their way to become the main differentiating element influencing buying decisions – and within the interior, the need towards premium, hygienic and sound-absorbing surfaces is on the rise.
