Hi,

Let us troubleshoot this echo issue in CapCut on your new laptop. Since it worked on your old one and you have already checked the main CapCut settings (Echo Reduction, Mute Project, Enhance Voice), the problem likely lies in the interaction between CapCut, your new laptop's hardware, or its system audio settings.

Here is a breakdown of things to check, moving from the most common/easiest fixes to more involved ones:

1. The Most Common Culprit: Audio Feedback Loop

   • Are you using headphones? This is the #1 cause of echo during recording. If you are not using headphones, the microphone might be picking up the sound coming out of your laptop speakers, creating a feedback loop (echo).
   • Test: Plug in a pair of headphones (even basic earbuds will do) and try recording the voiceover again. Make sure the headphones are set as your output device in your system's sound settings. If the echo disappears, this was the problem.
   • If headphones are the fix: Always use headphones when recording voiceovers to prevent the mic from hearing the speaker output.

2. Check System Sound Settings - Outside of CapCut

   • Sometimes, system-level audio settings can interfere.
   • Windows:
     • Right-click the speaker icon in your system tray (bottom right) -> Open Sound settings.
     • Go to Input -> Select your primary microphone. Click Device properties.
     • Look for a "Listen" tab. Make sure the box "Listen to this device" is UNCHECKED. If checked, it routes your mic input directly back to your output, causing an echo.
     • Look for an "Enhancements" or "Advanced" tab. Temporarily disable any system-level enhancements like "Noise Suppression," "Acoustic Echo Cancellation," or spatial sound effects. Sometimes these can conflict with CapCut's own processing.
     • Check Input Volume/Levels. Is it too high or boosted excessively?
     • Go back to Sound settings -> Output. Ensure your headphones (if using) or main speakers are selected correctly. Check their properties for any strange enhancements too.
     • Go back to Sound settings -> Manage sound devices. Look for any recording devices like "Stereo Mix" or "What U Hear". If you see them and aren't actively using them, try disabling them, as they can sometimes capture system audio and cause loops.
     • Check your laptop's sound settings to ensure the microphone levels are appropriately set and that no enhancements (like reverb or echo) are applied at the system level.
   • macOS:
     • Go to System Settings/Preferences -> Sound.
     • Click the Input tab. Select your microphone. Ensure the input volume isn't excessively high.
     • Check if "Use ambient noise reduction" is available and try toggling it off/on to see if it affects the echo.
     • Click the Output tab. Ensure the correct output device (headphones/speakers) is selected.

3. Microphone Selection & Type

   • Are you using the laptop's built-in microphone or an external USB/headset mic?
   • If built-in: New laptops sometimes have multiple microphones or beamforming arrays. Ensure the correct one is selected as default in system settings. Built-in mics can also be more prone to picking up internal laptop noise or vibrations that might sound like reverb/echo. Try recording slightly further away or changing the laptop's angle.
   • If external:
     • Ensure it's properly plugged in (try a different USB port).
     • Make sure it's selected as the default recording device in both your operating system's sound settings and potentially within CapCut if it offers microphone selection.
     • Check if the external microphone itself has any monitoring features enabled (sometimes called "sidetone" or direct monitoring) that could be causing the echo.

4. Update Audio Drivers

   • Since it's a new laptop, the default drivers installed by Windows/macOS might not be optimal.
   • Go to your laptop manufacturer's website (e.g., Dell, HP, Lenovo, Apple), find the support/drivers section for your specific model, and download/install the latest official audio drivers. Don't just rely on Windows Update. Restart your laptop after installation.

5. CapCut Specific Checks (Revisit)

   • Mute Project: Double-check that "Mute project" is definitely active while you are recording. Sometimes clicking elsewhere might deselect it.
   • Toggle Settings: Try recording without Enhance Voice and Echo Reduction enabled at all. Does the raw recording still have echo? If not, try enabling them one by one to see which one might be malfunctioning.
   • New Project: Create a completely fresh, empty project in CapCut and try recording. This rules out any weird project-specific setting corruption.

6. Physical Environment:

   • Room Acoustics: Recording in a room with hard surfaces can cause natural echo. If possible, try recording in a different room or add soft materials (like curtains or carpets) to absorb sound reflections.

7. External Microphone:

   • If you're using an external microphone, ensure it's compatible with your new laptop and functioning correctly. Sometimes, issues arise due to driver incompatibilities or hardware malfunctions.

8. Reinstall CapCut

   • As a last resort, if nothing else works, there might be a glitch with the CapCut installation itself on the new system.
   • Uninstall CapCut completely.
   • Restart your laptop.
   • Download the latest version directly from the official CapCut website or app store and reinstall it.

9. Alternative Recording Methods:

   • As a workaround, you can record your voice using a different application (like your laptop's built-in voice recorder or another audio recording software) and then import the audio file into CapCut. This method can help determine if the issue is specific to CapCut or a broader system problem.

Start with step 1 (headphones) and systematically work through the list. Pay close attention to step 2 (system sound settings), especially the "Listen to this device" option on Windows, as it's a very common cause of echo.
