Smartphones continue to improve in the ‘smart’ areas: better screens, faster processors, more memory, etc., but there’s not been a lot of innovation in the phone aspect of those devices. HD voice technology can change that, but since its introduction in 2009 hi-fi calling was only available on GSM networks… until now. Ericsson has just made the first HD voice call via CDMA — made possible by a new Enhanced Variable Rate Codec Narrowband-Wideband (EVRC-NW for the awkward acronym-loving crowd). The codec delivers sound in the 50Hz – 7000Hz range, which makes traditional calls limited to the 300Hz – 3400Hz spectrum sound like they’re coming from a drive-thru attendant at your local Mickey D’s. So far, the tech’s limited to the lab, but here’s hoping Ericsson lets it roam free to deliver the dulcet tones of our friends and family sooner rather than later.
