A common question for new station owners is how many people can tune in at the same time. The answer depends on two things: your listener slot limit and your available bandwidth, both of which relate to your streaming plan and your chosen bitrate. Understanding how these fit together helps you plan for growth and avoid turning listeners away. This guide breaks it down.
The two limits that matter #
Your maximum simultaneous audience is shaped by two separate limits, and the lower of the two is what you actually hit first:
- Listener slots: the maximum number of simultaneous connections your plan allows.
- Bandwidth: the total data your stream can send, which the bitrate and audience together consume.
How bitrate affects your capacity #
Every listener consumes roughly the stream’s bitrate for as long as they listen. That means a higher bitrate uses more bandwidth per person and reduces how many listeners you can serve within a given allowance. For example, at a lower bitrate you can support more simultaneous listeners than at a high bitrate, because each connection is lighter. This is why choosing a sensible bitrate is not just about audio quality, but also about audience size.
Estimating your capacity #
A simple way to think about it: your bandwidth use at any moment is approximately the bitrate multiplied by the number of listeners. To plan:
- Check your plan’s listener slot limit in your control panel.
- Note your streaming bitrate.
- Consider both together, since you are limited by whichever you reach first.
What happens when you reach the limit #
If you hit your listener slot limit, additional people trying to connect may be unable to join until a slot frees up. Reaching bandwidth limits can similarly affect playback. Neither is harmful, but both mean some listeners miss out, so it is worth planning ahead if you expect your audience to grow.
How to support more listeners #
- Lower the bitrate slightly to fit more listeners within your bandwidth.
- Upgrade your plan for more listener slots and bandwidth.
- Offer a lower-bitrate mount (Icecast) so more people can connect comfortably.
Troubleshooting #
- New listeners cannot connect: you may have reached your slot limit; consider upgrading.
- Playback issues during peaks: check bandwidth use against your plan.
- Unsure of your limits: they are shown in your radio control panel.
