Orange UK recently launched HD voice, which will give users much better audio quality during voice calls, I must admit I didn’t really think this was necesary at first, however the improvements are great.
If you scroll down you can see a video showing standard voice vs HD voice, it is a similar jump in quality as CD vs cassettes. I beleive that all carriers will soon begin offering a HD voice service.
At the moment there are only a handful of Orange handsets that support HD Voice, these are the Nokia E5, X6, 5230 and the Samsung Omnia Pro, however I am sure future devices will support HD voice as standard.
To give you a rough idea of how vast the improvement really is a standard phone call transmits audio at 6.6 kbps with frequency range of 300 to 3400 Hz, whereas a HD voice call transits audio at up to 23.85 kbps and a frequency range of 50 to 7000 Hz.
It is thought that this improvement will cause a lot more stress on Orange’s 3G network, let’s just hope Orange’s network is ready.
Do you feel the HD voice will become the standard in the future?
