Infineon integrated high-definition (HD) sound telephony into its VoIP products.

Infineon incoroprated HD sound telephony features into its VoIP chip sets, promising flawless audio quality.

Compared to traditional "narrowband" telephony, which works with a reduced acoustic bandwidth and represents a compromise between voice clarity and data rates, HD sound broadband technology uses a much wider transmission spectrum. "The result is greatly improved, more natural sound, not just for voice calls but also for other audio applications like MP3 and internet radio," said Infineon.
