How many Auracast receivers can co-exist

With the rise of Bluetooth LE Audio, one of the most exciting innovations is Auracast — a new feature that enables broadcast audio to an unlimited number of nearby receivers. Whether you’re tuning in with wireless earbuds at an airport gate or listening to a shared stream in a museum, Auracast is redefining what wireless audio can do.

But a common question arises:
How many Auracast receivers can co-exist in the same environment?

Unlimited Receivers, Just Like FM Radio

Unlike traditional Bluetooth pairing (which is one-to-one or limited multi-point), Auracast is based on broadcast audio. This means there is no technical limit to the number of devices that can receive the same broadcast. If 10, 100, or even 1,000 users want to listen to the same audio stream — they can, as long as they’re within range.

Auracast is ideal for:

• Airports and public announcements
• Silent conferences and guided tours
• Gyms, TVs in public spaces, or classrooms

What About Performance?

The performance and experience will depend on several factors:

• Signal strength and range
• Interference from other wireless signals
• The receiving device’s ability to handle LE Audio and Auracast

But fundamentally, the broadcaster doesn’t “know” how many receivers are connected — because receivers are passive listeners. This is similar to how FM radio or Wi-Fi beacons work.

Can Multiple Auracast Streams Run at Once?

Yes. Multiple Auracast transmitters can coexist in the same area, each broadcasting a different stream. Think of it like having multiple radio stations in a city. Users can scan for available streams and choose the one they want to listen to — for example, different TVs in a gym or languages in a museum.

To avoid confusion or interference:

• Each stream has a unique ID and metadata
• The UI on receiving devices helps users identify and join streams
• Optional encryption or access control can restrict private streams

Summary: No Limits on Listeners

So, how many Auracast receivers can coexist?
As many as you need. There is no hard limit.

This scalability makes Auracast a game-changer for public audio and accessibility use cases — from shared entertainment to assistive listening and beyond.
