In November 2011, Texas Instruments (TI) introduced an integrated circuit (IC) that simplifies the design and programming of spatially enhanced audio systems for multi-speaker portable products.

Features and USP: The National LM48901 quad Class D spatial array is the first in a family of innovative audio ICs that employ distributed sound processing coupled with loudspeaker array technology to produce an immersive audio experience for space constrained applications. It offers a complete audio solution by integrating a spatial processing DSP, four Class D amplifiers, an 18-bit stereo analogue-to-digital converter (ADC), phase locked loop (PLL), and I2S and I2C interfaces. This easy to use software tool speeds development by eliminating the need for algorithm tuning and inhouse DSP experts.
