By Staff, October 3, 2003
NVIDIA Corporation and Dolby Laboratories have unveiled details of a comprehensive validation program for motherboards and PC systems that offers a higher level of audio functionality, fidelity and performance. The new SoundStorm Program ensures NVIDIA nForce2-based motherboards and turnkey PC systems are designed and produced to the high-quality standards defined by NVIDIA, and must pass a rigorous testing process conducted by Dolby Laboratories before they will be validated as being Dolby Digital 5.1 and NVIDIA SoundStorm-compliant.
Motherboard companies and PC OEMs that introduce approved products will be afforded full marketing support and materials, and be allowed to use NVIDIA and the Dolby Digital logos and case badges for their product packaging, advertising and other promotional items. The following products have already passed the validation process, with more product approvals pending: Abit NF7-S motherboard; MSI K7N2G-ILSR motherboard; Shuttle SN41G2 small form-factor PC.
The NVIDIA nForce2 platform is the only core-logic solution available to include the realtime Dolby Digital 5.1 encoder technology in silicon
. This feature enables any audio source to be encoded as a true Dolby Digital 5.1 signal and output to high-quality PC speakers or traditional home theater systems over a single digital cable.
Motherboards and PCs will only be approved if they offer the following features and specifications:
NVIDIA nForce2-based motherboards must use the NVIDIA nForce2 MCP-T platform processor and include support for realtime Dolby Digital 5.1 encoding; discrete (non-shared) front left and right analog outputs; discrete (non-shared) rear left and right analog outputs; discrete (non-shared) center and subwoofer analog outputs; discrete (non-shared) S/PDIF digital output (coaxial recommended, but optical acceptable); discrete (non-shared) line-in analog inputs; discrete (non-shared) microphone analog input; minimum 85 dB signal-to-noise ratio on all analog outputs; minimum 80 dB signal-to-noise ratio on all analog inputs; and Dolby Digital testing and approval from Dolby and NVIDIA.
