Ultra-wideband voice technology will make your voice clearer and more real in Android Bluetooth calls, which are about to undergo a qualitative shift.
Even with the best wireless headphones, your voice doesn’t reach the other person’s ear right now, and it gets even worse if you talk on the phone while driving. While Bluetooth innovation has progressed significantly for paying attention to music, it hasn’t made an advancement with regards to call quality. Notwithstanding, Android might bring a superior calling experience to in-vehicle gadgets.
Mishaal Rahman, an expert in Android, discovered that a patch for Bluetooth Hands-Free Profile v1.9 was recently added to the Android Open Source Project repository. This configuration file, it is still in the draft stage. It will implement the more recent LC3 codec and shift the frequency range of voice transmitted by hands-free equipment from wideband voice (50Hz-7kHz) to ultra-wideband voice (50Hz-14kHz).
However, not at full bandwidth reproduction (20Hz-20kHz), which is what the majority of Bluetooth audio devices designed for consumer use are capable of.
This represents a significant improvement in Bluetooth call quality. Hardware manufacturers must, of course, continue their efforts, but at least the initial step has been taken.
