Multimedia technology company DnC Tech has developed what it claims is the world?s first codec using Microsoft?s next-generation digital audio format, Window Media Audio (WMA). The WMA?s 1/24 compression rate doubles that of existing MP3s, resulting in twice the data transfer speed and twice the memory. ?WMA has a higher compression rate and better sound quality compared to other digital audio formats. We are expecting it to become the next-generation audio format in the near future,? says Han-seo Park, CEO of DnC Tech.
The WMA codec can control various bit rates for encoding and uses a fixed-point DSP for low power consumption, enabling longer operation time with only one AAA battery. With these merits, it is well-suited not only for portable audio players like MP3 but also for voice recorders, VoIP, sound cards, CD R/W recorders, mobile handsets, PDAs, and Internet broadcasting systems. The WMA real-time decoder provides a play function at 5 to 192 kbps, and the encoder allows recording without a PC. The WMA codec algorithm is embedded on a fixed-point DSP, and a download upgrade is available through the Internet. The device supports a USB interface, line-in, a MIC and an LCD for portable players. The WMA chip features CD-level sound quality at 64 kbps.
Early this year, DnC Tech contracted with Microsoft to develop a Windows Media Video (WMV) encoding and video chip, targeting video streaming for portable devices such as video cell phones. The company hopes to establish a preeminent position as developer of all audio and video Windows Media Technology.
