Spirit's NetJet Tackles VOIP QOS

LONDON -- SPIRIT (www.spiritdsp.com/voip), the leading supplier of embedded software products for telecom and VoIP, announces enhanced version of its NetJet software targeted for VoIP communication.

SPIRIT NetJet is a set of state-of-the-art algorithms designed to improve voice-over-IP sound quality: Jitter Buffer, Packet Loss Concealment (PLC), and Forward Error Correction (FEC). The software successfully overcomes the problems of incoming network jitter and packet losses delivering toll speech quality even in multipoint conversations.

The solution is easily integrated in both wideband and narrowband systems. In narrowband mode, SPIRIT NetJet guarantees quality of PSTN telephony or better (8 kHz sampling rate). Moreover, it brings IP communication to the higher level by supporting 16kHz sampling rate in wideband mode.

The advanced version of the product has a dynamic jitter buffer adapting to network conditions and smoothing variations. Focused on speech quality SPIRIT developed NetJet to minimize speech distortions and provide PSTN quality or better in wireless communication.

"Delivering PSTN or better speech quality at wireless communication is the point SPIRIT is focused at." - says Andrew Sviridenko, founding CEO of SPIRIT. "In complex collaboration systems with a lot of users involved it's extremely important not to miss even a single sound. It was impossible with usual VoIP systems due to packet losses. SPIRIT NetJet handles the problem and makes life-like multipoint conferencing possible."
