Auracast Broadcast Audio is a new capability introduced by Bluetooth SIG that enables an audio source device – such as a smartphone, laptop, TV, or even a public address or sound system – to transmit Bluetooth audio to any number of in-range Bluetooth audio receivers – such as headphones, earbuds, or even hearing aids. Auracast™ broadcast audio will deliver life-changing audio experiences that will enhance the way we engage with others and the world around us. The Bluetooth Auracast™ broadcast audio solution developed by Realtek includes a Transmitter, Receiver, and Assistant. Realtek's Assistant solution also enables the control of Auracast™ Receiver to play audio from the Transmitter using existing smartphones. Additionally, it can be applied to assistive hearing systems, breaking limitations and offering a new auditory experience.
