Realtek Semiconductor Corp. has introduced a six-channel audio codec, the ALC650, that is designed to deliver high-performance sound to consumer-level PCs.

The AC-97 2.2-compatible codec provides playback functions at a 96kHz sample rate and can support DVD applications. It is said to be fully compatible with traditional two-channel interfaces.

Using the company's proprietary FlexJack technology, it can provide legacy interfacing with support for six-channel outputs at the back panel of a PC with a dedicated microphone input at the front panel, thereby eliminating the need for and the cost of an external bracket.

Davis Kung, Realtek's audio-product manager, said the codec provides an economical way to upgrade PC audio systems from basic two-channel to high-end six-channel performance, including a microphone function and surround sound.

The chip supports an advanced media player, sound-environment emulation, and karaoke mode.

The proprietary ALSRACK media player supports a variety of music file formats (CD, MP3, MIDI, WAV) and player skin changes. Emulation offers 26 sound environments, including concert halls, stadiums and pubs. The karaoke mode features voice cancellation, voice key adjustment and an equalizer function.

The ALC650 also supports Sony/ Philips Digital Interface input and output to facilitate digital connections with DVD systems or other A/V multimedia systems. It's priced at $20.
