DATASHEET
FOUR CHANNEL HD AUDIO CODEC
OPTIMIZED FOR LOW POWER/LOW COST
DESCRIPTION
The 92HD95 is a low power optimized, high fidelity,
4-channel audio codec compatible with Intel’s High Defini-
tion (HD) Audio Interface. The 92HD95 provides high qual-
ity, HD Audio capability to notebook and desktop PC
applications.
FEATURES

92HD95
SOFTWARE SUPPORT
• Intuitive IDT HD Sound graphical user interface
that allows configurability and preference settings
• Output Path Processing
• 12 band fully parametric equalizer
• Compressor/limiter allows higher average volume level
without resonances or damage to speakers.
• Enables improved voice articulation
• 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 audio connections made
• Input Path Processing
• 2 band fully parametric equalizer to allow for shaping of
microphone response
• Compressor/limiter allows higher average volume level
• Available near-field and far-field voice capture
algorithms to support conference room/lecture hall
applications
• Microphone Beam Forming, Acoustic Echo
Cancellation, and Noise Suppression
• IDT APO wrapper
• Enables multiple APOs to be used with the IDT Driver
• Dynamic Stream Switching
• Improved multi-streaming (Real Time Communication)
user experience with less support calls
• Broad 3rd party branded software including
Creative, Dolby, DTS, Waves, Sonic Focus & SRS
