The SHARC Melody Platform with Auto Room Tuner (ART) Technology is a product that offers optimized surround sound for the mass market. It utilizes digital signal processors (DSPs) to deliver high-quality multichannel audio experiences. With the increasing popularity of DVDs and the introduction of new multichannel audio formats, sales of home audio systems are expected to continue growing, and manufacturers are seeking ways to differentiate their products.
The SHARC Melody Platform integrates Auto Room Tuner (ART) technology to simplify the setup of complex audio systems and enable a better listening experience. This technology automatically measures and corrects the acoustics of a multichannel sound system for the specific room where it is set up, compensating for non-ideal room acoustics and speaker response. It is designed to bring high-end surround sound to mass-market buyers by reducing system and development costs.
