Ditech Networks (NASDAQ:DITC), announced today that it has released a new high definition voice solution for cable, mobile and VoIP network operators. Carriers using Ditech’s Virtual HD Voice solution can now offer virtual HD voice services to their entire customer base, even those who have not yet upgraded to HD enabled handsets.

“Cable, mobile and VoIP carriers are all looking to deliver HD Voice services to their customers,” said Todd Simpson, President and CEO of Ditech Networks. “There is a major challenge faced by carriers wanting to deliver HD voice; they need to both upgrade their networks to support Wide Band HD codecs and they need the handsets used on their networks to be upgraded to support HD voice. Ditech’s HD Virtual Voice solution enables carriers to offer a near HD voice experience today, even while their end-users are still using non-HD voice supported handsets.”

HD Voice delivers a higher quality voice transmission by extending the frequency of range of traditional or narrowband voice calls (300 Hz to 3400 Hz) out to wideband audio ranges (50 Hz to 7000 Hz). This expansion results in increased clarity and an overall better audio experience. Even when networks are upgraded to support HD voice, a call between an HD enabled handset and a regular handset would still sound like a non-HD call. Ditech’s HD Virtual Voice solution addresses this, delivering near HD voice quality even when the call involves a non-HD handset(s).

Ditech’s new HD Virtual Voice solution utilizes bandwidth expansion and warping to enhance transcoding between a Wide Band (WB) codec and a Narrow Band (NB) codec, while preserving the audio quality of Wide Band stream in the Narrow Band stream. A network upgrade with Ditech’s HD Virtual Voice solution takes about an hour. Carriers are invited to email sales@ditechnetworks.com to request a demonstration.
