NeuStar™ 4.0 - Improving Codec Performance and Audio Quality for Radio Broadcast
 We're proud to report NeuStar4.0 won the Radio World "Cool Stuff" award at the spring 2006 NAB convention |
NeuStar™ 4.0 is the newest generation of Neural Codec Pre-Conditioning™ hardware. You can run it as a stand-alone Codec Pre-Conditioner / Processor or in conjunction with traditional broadcast processing to add the benefits of Codec Pre-Conditioning™ to any signal path. Version 4.0 also features Neural Coding Load Analysis System (N-CLAS™) to dramatically decrease codec artifacts. This breakthrough in codec pre-conditioning actually predicts and visually displays when and where the coding artifacts will occur. Then it subtly modifies the content ahead of actual encoding.
NeuStar 4.0's patent-pending audio processing solution is not found in ANY other product. Coupled with Codec-Friendly™ audio processing, N-CLAS creates the perfect processing solution for low-bit rate audio applications. It allows broadcasters to maximize their codec performance while maintaining a "signature sound", making it the ideal tool for HD-Radio Multicast, Internet Streams, ISDN / POTS remotes, Satellite Syndication, STL protection, DAB, DRM, Podcasts, etc.
Key Features of NeuStar 4.0
- State of the art Neural Codec Pre-Conditioning algorithms featuring N-CLAS (Codec performance improvements are immediately audible)
- Codec-Friendly™ volume & spectral management tools not found in any other audio processor
- HD Radio™ codec specific feature set
- More DSP power than the original NeuStar
- Analog and Digital inputs from 32kHz to 96kHz
- Easier user interfaces including both front panel and TCP/IP web control
- Updates to legacy features found in NeuStar 1.0 and UltraLink
- User presets defined by both public and commercial radio broadcasters for extremely fast setup
- Fully upgradeable architecture for future software and hardware additions
NeuStar™ SW4.0
Neural Audio's NeuStar Codec Pre-Conditioning solution is also available in a software version running on Windows® operating system. See the NeuStar SW4.0 page for more information.
