Open Solution Co. (OSC) Ltd has released the DWM3000 digital audio processor which features the "apt-X" audio compress/decompress algorithm that enables the wireless transmission of CD-quality audio.

Designed for use in cellphones and wireless audio transmission devices, the device samples analog audio signals at 48kHz and converts them to 1.536Mbps digital data through an external 16-bit audio codec. The data then undergoes 4:1 compression for efficient transmission.

The chip features a robust FEC function and supports FHSS, AFS, fixed channel, and TDD modes. It consumes <20mA current.
