What Is Cellular Wideband Audio?

Cellular wideband audio is the newest way to talk on your phone. It's like having an entire symphony in your pocket! With cellular wideband audio, you'll get better sound quality and clarity than ever before, so you can tell if someone's lying to you from across the room. Plus, it looks great on any device there's no need to worry about compatibility or whether your headphones will work with the new technology. It works with wired and wireless/mobile networks, so whether you're at home or on the go, you can enjoy high-quality voice communication anywhere with cellular coverage. If you've ever been stuck in traffic and wished you could hear the other person on the other end of a phone call, then you'll be glad to know that Apple's new iPhone 5 offers Cellular Wideband Audio or HD Voice. This feature allows for crystal-clear voice quality, even when driving down the freeway at high speeds or talking on your phone from inside an airplane. Cellular wideband audio is the move toward high-definition audio. It extends the audio frequency of telephone line transmissions to a range of 50 Hz to 7 kHz and beyond. It aims to provide more transparent sound quality, easy classification of closely related sounds, and a better experience for both the talker and listener. The 3GPP has launched an advanced multi-rate wideband (AWB) codec to implement cellular wideband audio. The AWB codec is designed to provide higher-quality sound than traditional narrowband telephony services, which have been around since the 1980s. It also supports other advanced technologies like video conferencing, speech recognition and other applications that require high-quality audio. The AWB codec has emerged from extensive research into how humans perceive sounds in different environments and situations. The researchers found that humans can distinguish between different sounds even if they are at very similar frequencies or loudness levels; this helps us understand speech more clearly and also allows us to recognize familiar sounds easily, even when masked by other noises such as background music or crowd noise.
