Software Support
•
•
Intuitive IDT HD Sound graphical user interface that allows configurability and preference set-
tings
12 band fully parametric equalizer
• 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
Dynamics Processing
• Enables improved voice articulation
• Compressor/limiter allows higher average volume level without resonances or damage to
speakers.
IDT Vista APO wrapper
• Enables multiple APOs to be used with the IDT Driver
Microphone Beam Forming, Acoustic Echo Cancellation, and Noise Suppression
Dynamic Stream Switching
• Improved multi-streaming user experience with less support calls
Broad 3
rd
party branded software including Creative, Dolby, DTS, and SRS
Smart Configuration Suite (SCS) improves time to market and software quality
• Online pin and feature configuration tool generates BIOS verb table for Windows and Linux.
• Downloadable WHQL compliant, self configurable driver for XP, Vista and Win7 based on
verb table and test files generated.
• BIOS verb tables can be tested with the self configurable driver prior to flashing into BIOS.
