Sprint sends invitations to April 29 event, hints at HD Voice launch

Sprint event asks for attendees to 'hear it for yourself'

Sprint has sent out invitations to an event in New York, asking members of the press to "hear it for yourself." Though the invitation does not specifically mention what exactly will be demonstrated, the April 29th event is likely to be a formal unveiling of Sprint's delayed HD Voice service, and an announcement about the high-quality audio call's national launch.

CEO Dan Hesse, said to also be in attendance at the event, previously revealed that the carrier will be rolling out HD Voice to the majority of US markets this summer, "around the first of July." The service has already launched in a few select markets, Hesse advised, adding that he believed "Voice is still the killer app" for selling smartphones and mobile devices, and attracting new subscribers to its network.



HD Voice uses the Adapted Multi-Rate Wide Band (AMR-WB) codec for encoding calls, requiring double the bandwidth used for a 3G call. Claimed to improve the voice quality of a call by up to 40 percent compared to the 3G and 2G equivalents, the codec does so by enlarging the range of sound the call carries, from 3G's 300Hz to 2,400Hz range to a wider 50Hz to 7,000Hz spread. For it to be effective at all, both participants in the phone call need to use a compatible device, such as the iPhone 5s or the Samsung Galaxy S 4.

    Well. That only took 138 years. (Or 34 years, if we're only counting cell phones.)

    I suppose increased call quality is better late than never, although it's a little embarrassing how long the technology for this has existed without being in widespread use (apart from, you know, all of us who completely bypass the phone network by using streaming audio).
