Bluetooth Low Energy (LE) Audio is a new standard for low-power audio transmission over Bluetooth. As of right now, most TWE operate in a master/slave configuration: one earbud receives a single Bluetooth audio stream, keeps one set of channel data for itself and then feeds the other channel to the other earbud. For example, they can provide a better stereo imaging experience, make the use of voice assistant services more seamless, and make switching between multiple audio source devices smoother.”, Nick Hunn, The … A codec compresses audio for transmission over the air. These enhancements will be rolled into Bluetooth as a set of features known as LE Audio. LE Audio is the next generation of lower power, higher quality Bluetooth audio that operates on the Bluetooth Low Energy (LE) radio. However, these devices transmit relatively small amounts of data, without the added complexity of dealing with latency and audio compression. Broadcast Audio opens significant new opportunities for innovation, including the enablement of a new Bluetooth use case, Audio Sharing. A codec is what's used to turn a file of data into sound and now your hearing … He's invested in the Apple ecosystem, with experience covering Macs, iPhones, and iPads for publications like Zapier and MakeUseOf.
