Audio is where recordings most often fail. Here’s how to set it up so you don’t end up with a perfect video and zero sound.

CaptureGem saves recordings as .mp4, which makes quick “test clip → playback → adjust” loops painless. If you’re not using CaptureGem yet, start here: https://www.capturegem.com/

Decide what you need

Most people want one of these:

• Mic only (commentary)
• System audio only (platform audio)
• Mic + system audio (most common)

If you don’t need both, turn one off. Simpler = fewer failure modes.

Avoid echo and doubled audio

Echo usually happens when:

• Your mic picks up speakers (use headphones), or
• You capture system audio and the same audio re-enters via mic

Fix:

• Use headphones
• Lower mic gain
• Confirm you don’t have “listen to this device” enabled at the OS level

Quick test workflow (do this every time)

1. Start a 10-second test recording
2. Speak for 3 seconds
3. Play audio from the platform
4. Stop and review

You’re checking:

• Is mic present?
• Is platform audio present?
• Are they balanced?

Desync troubleshooting

If audio drifts:

• Reduce system load (lower fps/quality)
• Prefer hardware encoding
• Close extra tabs/apps

If you tell me your OS and your audio setup (USB mic? headset? virtual audio cable?), I’ll recommend a clean routing strategy.
