Why does my mic keep cutting out?
If the beginnings or ends of words disappear, or your voice breaks up during a call, first find out where it happens. A silent gap in a recording is not enough to prove packet loss, a faulty microphone or a network problem.
Compare a local recording with the calling app
Choose the same microphone in both places. Record a short phrase at your normal speaking volume, including a pause and a softer sentence. Listen to the saved file, then use the calling app's own microphone check if it has one.
- Words are missing in the local file: check the selected device, connection, input level and any processing used during that recording.
- The local file is clear, but the app's check loses words: start with that app's microphone settings.
- Both checks are clear, but people hear gaps in calls: investigate the live call and ask whether one listener or everyone hears the problem.
These comparisons narrow the next check; they do not prove a single cause. A microphone check inside an app may not follow the same route as an actual call.
If soft words or the first word disappear
Check whether your voice is consistently audible before increasing noise reduction or changing other controls. Use the low microphone volume guide if the recording is quiet throughout.
In Discord, check Voice & Video, the chosen input and whether you are using Voice Activity or Push to Talk. With Push to Talk, make sure the key remains pressed while you speak. Consult Discord's current troubleshooting steps for the controls on your device.
If your app offers noise or voice-detection controls, keep the original values and compare one change at a time. Processing that helps with room noise can behave differently with soft speech. Do not turn off every setting together.
If whole stretches of speech break up
Check for a loose connection or an input that changes when another device connects. If the issue happens only in live calls, use the real app's connection diagnostics or support guidance. Where practical, compare another network connection while keeping the microphone setup the same.
If only one person reports the interruptions, their connection and playback are also possible places to check. See why a clear recording can still sound bad in a call.
What MicProbe can and cannot establish
MicProbe lets you hear a local recording made with an approximation of the selected app's microphone settings. An interruption heard in that file is evidence about that recording, not a measurement of a real Discord, Zoom or Teams call.
A missing or unavailable interruption check does not mean that no interruption occurred. The call test's separate connection check uses a sample voice and reaches a nearby Cloudflare server; it does not follow the real app's network route or measure what another person hears.
Read the test's scope and limits. For continuous crackling rather than missing speech, use the microphone noise guide.
