AKM launches a new multi-core DSP for next-generation in-vehicle sound design: an immersive luxury audio experience



Asahi Kasei Microdevices Corporation (AKM) has released the AK7709VQ, a new multi-core DSP conceived for next generation in-vehicle sound design.  This powerful low-latency, 7000 MIPS/32-bit DSP enables real-time, large-scale computational processing, allowing for features such as advanced noise cancellation and engine sound generation.  With its support for the highest-resolution audio formats, the AK7709VQ delivers an extremely immersive listening experience.

In addition, AKM has developed a sound design demonstration board by combining the AK7709VQ with the flagship 135 dB SNR DAC, the AK4499EXEQ.  In addition to these devices, which boast our highest performance in both the digital and analog realms, the sound design board is built upon PCB design expertise unique to AKM, which has been highly regarded by the audio industry for decades.

Listeners (and passengers) will be able to experience a world of authentic, immersive sound “as if you were there" via the VELVET SOUND for Cars in-cabin experience.  This unique demo is made possible not only by AKM’s advanced technology, but also by the tuning performed by AKM audio engineers who continue to exceed the rigorous demands of the high-end audio industry.

The VELVET SOUND for Cars in-cabin experience is available at AKM’s Garage Laboratories in Tokyo, Shanghai, and Shenzhen. In the fourth quarter of 2023, this experience will also be available at our Garage Laboratories in North America and Europe. Please contact us with inquiries regarding this demonstration (this is intended for auto makers and Tier 1 suppliers).
