Keyboard sound on calls: when to switch it off
Whether other people on a call hear your typing depends on your speakers, your microphone, the call app's noise suppression and whether you are sharing audio. Here is how to tell, and a routine that avoids the problem entirely.
You like the sound of a keyboard while you work. Then a call starts, you take notes, and you wonder whether everyone else can hear the clatter too.
There are two separate sources to think about — the physical keyboard, and any typing sound your Mac plays — and they reach the call in different ways.
The physical keyboard
A mechanical keyboard, or any keyboard close to a laptop's built-in microphone, is picked up directly. The microphone cannot tell typing from speech; it records whatever sound reaches it.
What decides whether others hear it:
Distance and microphone type. A laptop's microphone sits a few centimetres from its own keyboard, so laptop typing is always audible to some degree. A headset microphone near your mouth picks up far less. A directional microphone pointed away from the keyboard less again.
The call app's noise suppression. Zoom, Teams, Meet and FaceTime all include noise reduction, and typing is one of the sounds they are trained to remove. It works well on steady background noise and reasonably on typing, but loud mechanical switches often leak through, especially while you are also speaking.
macOS microphone modes. During a call on recent versions of macOS, Control Center offers a Mic Mode option. Voice Isolation filters out much of what is not speech. It applies at the system level, before the call app sees the audio.
A typing-sound app
A typing-sound app plays sound through your Mac's audio output. Whether the call hears it depends on where that sound goes next.
Through speakers: the sound fills the room, and the microphone can pick it up just like any other noise. Echo cancellation in call apps is designed to remove the call's own audio from what the microphone hears, but it does not know about sound from other apps, and may let it through.
Through headphones: the sound goes into your ears, not into the room. The microphone does not hear it. This is the simplest fix of all.
When sharing your screen with computer audio: most call apps offer an option to share your computer's sound along with your screen, for playing a video to the group. Turn that on and everything your Mac plays is sent — including typing sounds — directly and clearly, regardless of headphones.
When recording: screen-recording tools that capture system audio will record typing sounds too.
How to check
Use your call app's test feature before an important call. Zoom and Teams both have a microphone test that plays your recording back. Type while it records.
Better still, ask one colleague once. "Can you hear me typing?" is a fair question, and the answer applies to every future call on the same setup.
A routine that avoids the question
For the physical keyboard:
- Use a headset or external microphone rather than the laptop's built-in one.
- Turn on Voice Isolation or your call app's strongest noise suppression.
- Mute yourself while typing if you are not speaking. It is the most reliable filter there is.
For typing sounds:
- Wear headphones on calls. Problem solved for ordinary calls.
- Turn the sound down or off before you share your screen with audio, or before recording.
- If you present often, make turning it off a single action rather than a trip into settings.
Courtesy, not only acoustics
Even when the call cannot hear it, a loud keyboard sound in a shared room affects the people next to you. A good typing sound is one you can hear and your neighbour cannot — which usually means headphones or a low volume.
What ClackSmith does
ClackSmith plays keyboard sounds from the menu bar through the audio output you choose, so you can send them to headphones specifically while other sound goes elsewhere. Volume is adjustable in the menu, and also through Shortcuts — so turning ClackSmith down before a screen share can be one shortcut rather than a menu hunt.
It does not listen to your microphone and does not interact with call apps at all. It also requests neither Input Monitoring nor Accessibility: it reacts to count-only key-down and key-up values from macOS, without receiving which key you pressed, and keeps no keyboard activity history. Modifier-only presses and key autorepeat do not trigger sounds.
