If you want your microphone to stop sending low-level sound during pauses in XSplit Broadcaster, the closest built-in control is Noise Gate. XSplit does not document a feature called “silence detection”: its gate works by blocking audio below a threshold that you set yourself.
You can find the gate in Audio Effects and tune it while watching the microphone’s VU meter. Noise Suppression is a different effect that automatically detects and removes noise; it does not use the same manual threshold.
Does XSplit have silence detection?
Not under that name in XSplit’s official guidance. The relevant control is Noise Gate, which passes audio above a manually chosen level and blocks it below that level. That distinction matters: a gate responds to signal level, not to whether XSplit understands that you are speaking or whether a sound is unwanted.
A pause in speech is often quieter than ordinary speech, so a gate can reduce the microphone output during pauses. But a quiet word, a soft breath, or the beginning of a sentence may also fall below the threshold. If that happens, the gate can block part of something you meant to say. Conversely, a room sound above the threshold may still pass even when you are not speaking.
The practical goal is therefore not to find a universal “silence” setting. It is to find a threshold that separates the quiet background in your room from the softest speech you want listeners to hear. Your microphone, distance from it, room noise, and speaking style all affect that balance. XSplit does not publish a universal recommended threshold number, so do not treat a value from someone else’s setup as a reliable starting answer.
This is an audio effect for the microphone in your XSplit mix. It is not a control for ending or pausing the YouTube broadcast, and it does not decide what happens to silence in the video itself. If your channel uses a prepared video loop rather than a live microphone, first establish whether the mic is contributing audio at all; the gate only concerns the audio signal routed through that device.
Find the microphone and Audio Effects
Before changing an effect, confirm that XSplit is listening to the microphone you intend to use. Open Tools > Settings > Audio and check the capture device selection. This prevents a common source of confusion: adjusting a gate while monitoring one input, then broadcasting a different input or a duplicate device.
Next, open Tools > Audio Effects. XSplit also documents a route through the gear icon beside the microphone dropdown in Audio settings; that opens the Audio Effects properties. Labels and placement can shift between versions, so if one route does not look familiar, use the other and check XSplit’s current Audio Mixer and Effects guide.
It helps to keep the Audio Mixer open while you configure the effect. XSplit describes it as a way to monitor devices individually and check levels. Speak into the selected microphone and look for activity on its meter. If there is no movement, verify the device selection, connection, and operating-system input settings before trying to solve the problem with a gate.
A meter that moves for the wrong device is not a useful tuning reference. If you have a headset mic and a webcam mic connected, for example, make sure the movement you see belongs to the headset input you plan to use. You can also check XSplit’s Audio settings documentation for the capture-device context.
Enable Noise Gate
In Audio Effects, enable Noise Gate for the microphone. XSplit’s description is straightforward: audio above the threshold you set is allowed through, while audio below it is blocked. Think of the control as a level boundary, not an automatic speech recogniser. It does not decide that a sound is a voice and let it through because of its meaning.
Once enabled, leave the effect on while you test. If your controls include a threshold adjustment, make small changes and listen after each one. Moving the threshold upward blocks more low-level signal, but it also increases the chance that quiet speech will be cut off. Moving it downward preserves more quiet speech but may let more background sound through.
Do not start by raising the threshold until the meter appears quiet. A gate can make the meter look inactive in pauses while also hiding soft speech that matters. A devotional introduction spoken gently, a study-channel aside, or the first syllable of an announcement can be quieter than the voice you use when checking the mic. Test the way you will actually speak during the channel, not only with a loud “check one, two”.
If you do not see Noise Gate in the place expected, first confirm you opened the audio effects for the microphone rather than an unrelated source. Check the current XSplit help page rather than assuming another application’s menus or terminology apply. A feature with a similar name in another broadcaster may have a different behaviour or controls.
Set the threshold with the VU meter
Use the live VU meter as a reference while the microphone receives both quiet background sound and speech. The aim is to keep ordinary room noise below the gate while keeping the quietest speech you need above it. The meter helps you see the relative levels in your setup; it does not provide a universal setting that will work for every room.
A useful tuning pass has three parts. First, stay quiet for a moment and observe the meter’s normal background movement. Then speak at your usual level, including a deliberately softer phrase. Finally, pause again and listen to what the output does. Change the threshold gradually, repeating the same phrases, so you can tell whether a difference came from the setting rather than from speaking more loudly.
If background sound still passes during a pause, raise the threshold a little and repeat the speech test. If a quiet word or the start of a sentence disappears, lower it. Those adjustments follow from the gate’s documented threshold behaviour; they are practical tuning guidance, not a threshold value prescribed by XSplit. You may not be able to remove every room sound without affecting some quiet speech. In that case, reducing the noise at the source—moving the mic closer, lowering a fan, or choosing a quieter room—may be a better trade-off than pushing the gate harder.
Watch the meter for clipping as well as for the gate’s activity. XSplit advises keeping levels below the red range to avoid clipping or crackling. A gate does not repair a signal that is already distorted because the input level is too high. Set a sensible input level first, then tune the gate against that signal rather than using the threshold as a substitute for gain control.
Repeat the check after you change microphone distance, gain, or room arrangement. A threshold that worked when you sat close to a desk mic may no longer suit you if you move further away. Likewise, turning on a fan or moving to a noisier room can shift the background level. It is worth checking the meter and listening again before relying on the setup for a long session.
Noise Gate versus Noise Suppression
Noise Gate and Noise Suppression address unwanted microphone audio differently. XSplit describes Noise Suppression as automatically detecting and removing noise. A gate instead relies on the threshold you choose: it blocks signal below that level and passes signal above it. They are separate effects, not two names for the same automatic silence feature.
| Control | What triggers or shapes it | When it may help |
|---|---|---|
| Noise Gate | A manually set audio-level threshold; signal below it is blocked. | Reducing low-level microphone output during pauses. |
| Noise Suppression | Automatic detection and removal of noise. | Treating background noise without manually setting a level boundary. |
| Push to Talk | A hotkey controls whether the mic is muted or available. | Keeping the mic muted until you choose to speak. |
The trade-off follows from the trigger. A gate can make pauses quieter, but any wanted sound below its threshold can be cut off and unwanted sound above it can pass. Suppression is intended to remove noise automatically, but it is not the same as a hard level boundary. Do not raise the gate threshold expecting it to behave like suppression, or assume suppression will mute every pause.
Push to Talk is different again. XSplit says that assigning a Push to Talk hotkey automatically mutes the mic until the hotkey is pressed. That is a deliberate, user-controlled mute, not a threshold-based response to quiet audio. It may suit a channel where you only need occasional spoken announcements, though it requires you to remember the hotkey each time.
Choose the control based on what you want to happen. If low-level room sound during pauses is the main issue, try the gate and test quiet speech carefully. If you want automatic background-noise treatment, assess Noise Suppression separately. If you want to decide manually when the mic is open, consider Push to Talk. For a continuous music or ambience broadcast, also consider whether a live microphone should be in the mix at all; our guide to running a 24/7 Gujarati instrumental radio stream discusses the channel context rather than treating a microphone effect as a substitute for a clean source.
Test quiet and loud passages
Do not judge the gate from the meter alone. Record a short local test or use a private rehearsal method that lets you listen back, then check the result at normal listening volume. Listen for the beginning and ending of words, not just the loud middle of a sentence. The meter can show that a signal crossed a level boundary; only listening tells you whether the result sounds natural.
Use phrases that match the real job. If you host a devotional channel, test a softly spoken welcome and a normal-volume announcement. If you explain a lesson, test a quiet aside and a louder emphasis. Include a pause long enough to hear what happens to room noise, then resume speech without deliberately shouting. The test should reveal whether the gate opens in time for your normal voice and closes when the room is otherwise quiet.
Also test other sounds you want listeners to hear. A soft musical cue or another person speaking near the microphone may sit below your voice’s usual level. The gate cannot know whether such a sound is intentional. If it is routed through the gated microphone, it will be treated according to its level just like any other input.
Make one adjustment at a time. If the first syllable is clipped, lower the threshold and repeat the same phrase. If a steady background sound remains audible in pauses, raise it slightly and repeat. If you cannot find a comfortable balance, consider changing mic placement or reducing the background at its source instead of forcing a threshold that damages speech.
Finally, check that the Audio Mixer level stays below the red range while you speak at your loudest expected level. XSplit’s mixer guidance warns about clipping and crackling when levels enter that range. A clean gate setting cannot compensate for clipping earlier in the audio chain. Once the setup sounds acceptable, check it again at the start of a real session, especially after changing devices or settings.
For a 24/7 channel, the microphone test is only one part of preparation. If your plan is to leave a computer running all night, account for power and the possibility that a local setup needs attention; our desktop electricity cost guide covers that separate operating question. If your priority is having a prepared video continue while your own computer is off, StreamNeo removes the specific burden of keeping that computer running, but it does not replace deciding what audio belongs in the source or checking YouTube’s current requirements.
Keep the audio setup in context
A microphone gate is a small part of a live channel’s sound path. It changes what reaches the mix from one input; it does not make the underlying recording cleaner, prevent every interruption, or ensure that all sounds in a broadcast are appropriate. Keep the effect’s purpose narrow, and test the full mix when other audio sources are present.
If your channel is built around prerecorded audio or video, verify which source supplies the sound and whether the microphone is needed. A silent microphone channel with the wrong input selected can lead you to tune an effect that has no bearing on the audio viewers hear. Check the mixer during a representative test and confirm the intended source is active.
If the gate clips words, there are several sensible responses: lower the threshold, improve the signal-to-background ratio by moving closer to the microphone, or use a different control if deliberate muting better suits the format. There is no requirement to use Noise Gate just because it is available. A clean, continuously audible voice can be preferable to aggressive gating that makes a channel sound as if it is switching on and off.
XSplit’s official advanced tips and support pages are the best place to check if your interface differs from the directions here. The available research did not establish a universal threshold or a hands-on tested setting, so the important step is to tune against your own meter and listen to the result.

FAQ
Is Noise Gate the same as silence detection in XSplit?
No. XSplit’s documentation calls the effect Noise Gate, not silence detection. It blocks audio below a threshold you set manually, so it responds to signal level rather than identifying silence or speech.
Where do I find Noise Gate in XSplit Broadcaster?
Open Tools > Audio Effects, or use the gear icon beside the microphone dropdown in Audio settings to open Audio Effects properties. Confirm that the selected microphone is the one you intend to adjust before tuning the effect.
What should I set the Noise Gate threshold to?
XSplit does not publish a universal recommended threshold number. Watch your microphone’s VU meter and test background noise alongside your quietest normal speech, lowering the threshold if speech is blocked and raising it cautiously if low-level background sound passes.
Should I use Noise Gate or Noise Suppression?
Use Noise Gate when you want a manually chosen level boundary to block quiet signal. Noise Suppression is a separate automatic noise-removal effect; test it on its own rather than treating it as an automatically controlled gate.
