Fix Microphone Echo In A Screen Recording

Check The Signal Path

1. Use headphones when monitoring sound, so the microphone does not pick up your speakers.
2. Check Audio source and choose only the input you need. A microphone records the room as well as your voice.
3. Check whether Windows or another app is monitoring the same input back to speakers. Disable unwanted duplicate monitoring using that app’s own controls.
4. If a meeting app is already playing your voice back, test the recorder outside that meeting to isolate the source.
5. Save and play a short MP4 test with headphones, adjusting the input level if the voice clips or distorts.

Know The Current Audio Controls

The simple recorder selects one DirectShow audio source at a time and defaults to No audio. System sound needs an appropriate Stereo Mix, loopback or virtual capture device that is already available on your PC. An ordinary microphone records microphone sound. This package does not install an audio helper driver or mix microphone and system audio together.

A loopback or virtual source can itself contain a mix created elsewhere. Avoid selecting or configuring the same sound path twice. Animated GIF never contains sound.
