 "TI Adds Wideband Codec To VoIP Portfolio")
Texas Instruments (TI) has announced technology enhancements to its Voice over IP (VoIP) solutions portfolio that claim to drive voice applications even closer to a high-definition (HD) experience.
TI is licensing the Low Delay AAC super wideband codec. Powered by TI’s digital signal processors (DSPs), the MPEG-4 AAC-LD super-wideband codec claims to offer substantial benefits compared to earlier wideband audio technology, with the ability to make ubiquitous HD voice a reality in global IP networks.
Able to transmit voice at a sample rate of up to 48 KHz, super-wideband codec technology provides near-CD quality audio at data-rates of 48 – 64 kbps for better clarity with applications like IP-based voice and video, as well as transmission of music over the telephone.
With this new super-wideband technology, TI’s VoIP solutions can deliver CD-quality sound on both ends of a VoIP-enabled phone call, while supporting a full range of voice and music capabilities. Leveraging DaVinci technology processing performance and TI’s VoIP platforms, the AAC LD super-wideband codec claims to support real-time IP applications including multimedia integration, HD audio and rich, robust sound quality.
