In short
- The sound in the room and the sound in the stream are two separate signals.
- Remote viewers only hear what is sent to the stream, not what the hall hears.
- Check the stream with headphones, away from the room, not by listening in the hall.
- Ask who owns the room's sound system and how the stream will connect to it.
The room and the stream do not share one soundtrack. The hall’s speakers serve people in the room. The stream gets its own audio feed. You need to check both, and the stream needs its own test.
Why is the stream’s sound a separate check?
Think of two lines running from the same microphone. One goes to the hall’s speakers. The other goes to the streaming equipment. They can differ in level, quality and which sources they include.
A hall can sound good because the speakers are tuned for that room and the speaker stands close to the audience. Online, the same event may sound thin, echoey or quiet because the stream is taking its sound from somewhere else.
Which sources might the stream take?
| Source | What it is | Watch out for |
|---|---|---|
| Feed from the venue’s sound desk | The mixer’s signal sent to the stream | Needs the venue’s agreement and a test; level may need adjusting for online |
| Own microphones for the stream | Lapel or hand-held microphones set up for the stream | Extra equipment and set-up time |
| Camera microphone | The built-in microphone on the camera | Picks up the room and the crowd, not just the voice |
| Separate recorder | A recorder near the speaker | Needs to be joined to the stream or used in editing later |
| Remote guest audio | A speaker joining online | Must be sent into the room and into the stream, in both directions |
Most events use a mix of these. The point is to know which ones the stream uses, speaker by speaker, before the day.
What can go wrong online but not in the room?
- A speaker’s microphone is on the hall system but not on the stream feed.
- Music from a laptop plays in the room but never reaches the stream.
- A remote guest can be heard online but not in the hall, or the other way round.
- The stream carries room echo because it is using a camera microphone.
- The stream’s level is much louder or quieter than the hall.
- The stream sound runs behind the picture or the room, a matter covered in communicating a stream delay to the event team.
How do you check the stream’s sound?
- Ask for a test stream before the event, ideally in the venue with the real equipment.
- Listen on headphones from a separate device, away from the hall.
- Test each source: every microphone, any playback and any remote guest.
- Speak in the voices you expect: soft, loud and far from the microphone.
- Listen again after any change, because a new microphone or a moved cable can alter what goes out.
This belongs with the broader rehearsal described in rehearsing a livestream with remote speakers. For overall audio planning, the sound planning hub and our event audio brief builder help you write down what you need.
Who is responsible for what?
The venue or its audio-visual supplier usually runs the hall’s sound. Our team runs the stream. The link between them is a shared job. Agree before the day who connects the cable, who adjusts levels, and who is on site if the venue changes the setup.
If the event mixes people in the room and people online, see recording online and in-room speakers in a hybrid event. If the video also goes to screens in the hall, the handoff is covered in delivering camera video to venue screens.
What we confirm for your event
- Where the stream takes its sound from, speaker by speaker.
- Whether we can connect to the venue’s sound desk, agreed with the venue beforehand.
- A test stream before the day, and who listens to it.
- How remote guests are heard in the room and in the stream.
- The backup if a microphone fails.
Our livestream planning checklist includes audio checks alongside connection and access. To scope the work, see the event livestreaming service.
Tell us who speaks, what microphones the venue provides and who will watch online. We will suggest how the stream should take its sound and confirm what is possible for your date.
