ZIRENE® CAR is a world-class digital signal processing solution capable of enhancing the audio in in-car entertainment systems. The solution is purely software based and can be integrated in embedded platforms like Android, Linux and Windows, and is also portable to dedicated hard-ware platforms like NXP chipsets. 

In-car entertainment has become an important differentiator in the automotive market. Devices like multimedia players and navigation systems are now fully integrated into the car by the manufacturer.

The physical nature of car loudspeakers systems makes playback conditions far from ideal. This is caused by several factors such as low mounting of main loudspeakers, absence of tweeters, asymmetrical position of loudspeakers relative to the listeners, obstruction of direct sound path by passengers and car seats, and high sound absorption of interior. The result is typically a sound field dominated by individual loudspeakers, sound coming from below, poor timbre, and lack of bass and treble.

To overcome these limitations, ZIRENE® CAR offers state-of-the-art audio enhancement technologies for loudspeaker playback optimization, spatial audio effects and sweet spot creation. ZIRENE® CAR offers maximum effect on small loudspeakers with profound surround sound effect. The natural sound image is enlarged beyond the physical loudspeakers and listener position is optimized relative to loudspeakers.

The main advantages of ZIRENE® CAR include

  • Powerful sound even with a few number of physical speakers, e.g. no tweeters
  • Optimum listener conditions with sweet spot auto calibration
  • Intense and deep bass without a physical sub-woofer

ZIRENE® CAR increases the volume and equalises the loudness level while protecting the loud-speakers from overdriving. The solution offers HD sound quality and creates multi-channel output regardless of the number of input channels.

The solution is fully customizable to specific car models with easy integration and tuning. For several years, AM3D has supplied Kia Motors with AM3D's patented Power Bass audio enhancement solution.
