This white paper explores how DSPs provide the real-time performance necessary to provide high-quality voice services for VoIP devices and infrastructure equipment. The author explains how programmable devices like DSPs provide a certain level of “future-proofing”, such as the ability to upgrade to new algorithms and codecs in the field—a major benefit for equipment vendors, service providers and end users. Finally, as the market continues its progression with next-generation capabilities such as wideband audio and high definition video, the white paper considers how DSP technology, with its unique combination of real-time processing, scalability and low power consumption, will play an even greater role in the future growth of IP communications.
