What good room audio sounds like

Three things you can hear in the first ten seconds

Good room audio is not a quality you either notice or do not. It is three specific properties, and each one is obvious once it has a name. Every well-set-up room has all three, and almost no badly set-up room has any of them, which is why the judgement takes seconds rather than minutes.

1. Close

   The voice has weight to it. Consonants land rather than dissolving, and a whisper is still a whisper instead of vanishing. This is distance, and nothing else produces it.

2. Dry

   When a word stops, it stops. Nothing trails after it and nothing comes back off a wall a fraction late. A dry room sounds smaller and much closer than it actually is.

3. Separated

   You can tell the voice, the fan, the bed and the chair apart instead of hearing one mixed blur. Separation is what lets you follow speech without concentrating on it.

Those three come almost entirely from where the microphone is, which is why a headset beats a laptop lid so completely. A headset microphone sits a few centimetres from the mouth and travels with the head, so the voice is permanently the loudest thing in its world and everything else is a distant background. A lid microphone is a metre away, aimed past the person at the ceiling, and screwed to the same piece of plastic as the fan and the keyboard — so it hears the case it is mounted in, then the room, then the person. Open two rooms and guess which is which ; you will be right nearly every time, without looking at either setup.

There is a second, quieter benefit. A close microphone lets a performer speak at normal volume rather than projecting across the room, and a normal speaking voice sounds like a person talking to you. A raised one sounds like an announcement. Rooms where the audio is close tend to be gentler and more conversational for that reason alone, and it has nothing to do with the personality of the person in them.

Echo is the room, and soft things eat it

Echo in a bedroom is not a cathedral effect. It is short, and it sits so close behind the voice that most people hear it as "hollow" or "boxy" rather than as an echo at all. What is happening is that a hard floor, bare walls and a hard desk are sending copies of every word back at the microphone slightly late, and those copies pile up underneath the next word.

The tell is what happens at the end of a sentence. In a dry room the last word simply stops. In a hard room there is a short tail after it, and the more the performer raises their voice, the longer the tail gets. That tail is what makes you turn the volume up and then find it is no clearer than it was.

None of that costs anything, which is the useful part of knowing it. A plain bedroom with a rug and a duvet beats a much more elaborate-looking room with a hard desk and a bare wall, every time. Listen to the ends of sentences across a few rooms and you will start placing people's furniture without being shown it.

Music beds are usually the wrong fix

A music bed almost always arrives as a solution to a different problem. The room sounded empty, or hummed, or the performer was nervous about silence, and music covered all three at once. It works, briefly, and then it costs more than it saved — because the thing it covers best is the voice.

A track is continuous and a voice is not. The voice appears in gaps, pauses, changes direction and drops to a murmur; the music does none of those things and does not get out of the way for any of them. So the parts of speech that carry the most — the quiet aside, the end of a sentence, the answer to something you typed — are exactly the parts the bed swallows. You end up catching roughly one word in three and deciding the room is not for you, when in fact the room is fine and the track is winning.

There is a second cost that is easy to miss. Music flattens the specific noises that prove a room is live: a chair moving, a breath, a laugh cut short, the small silence before an answer. Take those away and a live room starts to feel like something playing at you. The rooms with no bed at all sound noticeably nearer , and that is the whole reason, even though almost nobody names it.

Watch what happens when someone speaks. A performer who pulls the music down for a reply and pushes it back afterwards has understood the problem and solved it. One who lets the track run unchanged through every answer has not thought about it, and the room will stay that way for the whole visit.

When the sound drifts away from the picture

Sooner or later you open a room where the voice arrives slightly after the mouth does. It is disorienting out of proportion to how small the gap is, because you read faces without deciding to and the mismatch keeps interrupting that.

Most of the time it is not permanent and not anybody's fault. Sound and picture travel as separate streams and are put back together at your end; anything that briefly interrupts one of them can leave the two slightly apart afterwards. It often corrects itself, and a reload fixes most of what is left. The thing worth knowing is how to tell whose problem it is:

• Reload first. It is one click and it resolves the majority of cases outright.
• Then open a different room. If that one is clean, the first room was having a moment and there is nothing at your end to fix.
• If several rooms drift the same way, it is your connection or your machine, and no amount of room-hopping will help.
• If it returns in the same room after every reload, it is their setup. That is a room to come back to another night rather than a room to fight with.

Thirty seconds of that saves you blaming the wrong end for an hour. Test it against whatever is live now — it costs nothing to open a second room, and the comparison is the entire diagnosis.

What good sound tells you about everything else

Here is the part that makes all of this worth more than it first appears. Nobody compliments audio. Viewers say a room looks good; they never say it sounds good, even when the sound is the reason they stayed. So a performer who has moved the microphone, put a rug down and turned the music off did it without any prospect of being thanked for it. They did it because they thought about what the room is like from your side.

That is an unusually reliable signal, and it rarely travels alone. The rooms that sound considered tend to be the ones where chat gets answered, where questions are heard the first time, and where the person seems aware that there are people on the other end rather than a counter. None of that is guaranteed by good audio. It just keeps turning up alongside it.

The reverse holds too, and more strongly. A microphone still in a laptop lid two metres away usually means nobody has stood on your side of the screen and asked what this is like. Often that is the only thing wrong, and it is worth saying once in chat rather than leaving. You need a free account to type , and it is the only part of this page that requires registering.

If you do decide to spend, sound is the fairest thing to judge it on. Tokens land around $0.08–0.12 each depending on bundle size; a public tip of 15–100 tokens buys you an answer out loud, which is worth very little in a room where you cannot make the answer out. A private show at 6–90 tokens per minute is the same voice with nobody talking over it — excellent value in a room that already sounds close and dry, and a waste in one that does not. A room with roughly 20–200 viewers is where you can still hear an answer land.

Judge the audio first, in public, for free, and the spending decision more or less makes itself.

Frequently asked questions

What is the single biggest difference between a good-sounding room and a bad one?

How far the microphone is from the mouth. Everything else — echo, hum, keyboard noise, music — gets quieter the moment the microphone moves closer to the person, because the voice arrives louder and the room has less room to compete.

Why does a headset beat the microphone in a laptop lid?

Distance and mounting. A headset microphone sits a few centimetres from the mouth and moves when the head moves, so the voice is always the loudest thing it hears. A lid microphone is a metre away, aimed past the person, and bolted to the same case as the fan and the keyboard.

Can a performer fix echo without spending anything?

Usually yes. Echo is a hard-surface problem, not an equipment problem. A rug, a duvet, curtains, an open wardrobe and a room that is not empty will each take a bite out of it. Moving away from a bare wall does more than most purchases.

Sound and picture keep drifting apart. Whose end is that?

Test it on another room. If the next one is fine, it was theirs and it will often settle by itself. If several rooms in a row drift the same way, it is your end, and a reload is the first thing to try.

Does good audio actually mean a better room?

It correlates more than you would expect. Sound is the part nobody compliments, so a performer who has fixed it did it for the viewer rather than for praise. That attention usually shows up in the rest of the room too.

Is listening to all this free?

Yes. Public rooms open with sound on, with no account and no card. Registering is free as well and adds chat, follows, notifications and a block of starter tokens.
