MAPX is a product of Qualcomm Technologies International, Ltd.

MAPX audio processor

The MAPX audio processor is an integrated, high-performance audio system-on-chip (SoC) for soundbars, speakers, entry level AV receivers, home theater systems and integrated audio systems. MAPX is extremely versatile and allows developers to design a wide variety of end products with minimal incremental PCB design effort because of the commonality of device variants across the range.  All MAPX solutions are designed to be software compatible with each other and pin-to-pin compatible for the same package. This makes it easy for developers to switch between different devices to create unique products with varying feature sets quickly and easily.
