DATASHEET

10-CHANNEL HIGH DEFINITION AUDIO CODEC

Description

The 92HD700 is a Theater Quality 10-channel audio

CODEC that enables systems with 7.1 audio playing

simultaneously with VoIP or another stereo audio stream.

IDT's proprietary SD technology provides high fidelity with a

DAC SNR of 95dB.

92HD700

Software Support

•

SKPI (Kernel Processing Interface)

•

Enables plug-ins that can operate globally on all audio

streams of the system

Constant, system-level effects tuned to optimize a

particular platform can be combined with user-mode

“presets” tailored for specific acoustical environments

and applications

System-level effects automatically disabled when

external connections made

Enables improved voice articulation

Compressor/limiter allows higher average noise level

without resonances
