How to Fix CapCut Audio Delay [Easy Guide]

If you’re a TikTok or Reels creator, you’re no stranger to CapCut. It’s a popular video-editing app that lets you unleash your inner creativity, allowing you to create and share stunning clips for your socials. However, it isn’t without its faults, with audio delay being one of the most common problems users often have with CapCut.

When the audio isn’t properly synced with the video, we call it an audio delay or “lip-sync error”. Usually, the primary cause behind it in CapCut is the mismatch between the video’s frame rate and the audio track’s sample rate.

For those uninitiated on the technical terms, the “frame rate” is the number of frames (or images) displayed per second in a video. The “sample rate” is the number of samples (or units) recorded per second in an audio file. If these two rates don’t match, you’ll notice the audio is ahead or behind the video, sometimes by a slight or substantial margin.

Fortunately, we have a few possible solutions to offer. This troubleshooting guide to fixing CapCut audio delay will highlight them in detail.

How to Fix CapCut Audio Delay [Solved]

CapCut Audio Delay

Use Wired Headphones When Editing

You’d be surprised how often this audio delay in finished exports stems from user errors. Chances you’ve been using your AirPods or some other wireless pair of in-ears or headphones during the editing phase – but why would that be an issue?

The answer is latency. You see, wireless headphones and speakers use Bluetooth to connect to your mobile or desktop, and this exchange contributes to some amount of latency. It’s just the inherent flaw of the technology, which necessitates encoding and decoding the audio stream during transmission and reception.

When editing in CapCut, this latency can cause a noticeable delay between the visuals and the audio, making precise edits difficult. Actions such as cutting, trimming, or synchronising audio with specific video frames become inaccurate because of the delayed audio feedback.

That’s why we recommend using wired headphones, which connect directly to your devices over a 3.5mm auxiliary jack, USB-C, or Lightning port, to eliminate this audio delay. In this case, the audio response is instantaneous, and it allows for more accurate and precise editing in CapCut.

Convert Your Videos

If it isn’t your headphones, the next step to resolving the audio delay is to run your source video and audio files through a conversion tool with the same export settings applied before importing them into CapCut. It’s to ensure the video frame rate and audio sample rate across all your files remain consistent and in sync during the editing and after the exporting process.

Free open-source software, such as HandBrake and fre:ac (, get our top recommendations for transcoding your video and audio files. Similarly, mobile users should find several free-to-use media conversion apps and websites.

Using these tools is relatively straightforward. All you have to do is add your video and audio files to the app (or upload them to the website). You can usually drag and drop them or use the “Browse” button to choose from your device’s storage. Pick an output format CapCut natively supports (e.g., MP4, MOV for video and MP3, AAC for audio).

You can also customise other settings, such as resolution, frame rate, bit rate, sample rate, codec, quality, etc., usually under the “Video” or “Audio” tab in the config window. It’s better you set a fixed frame rate and sample rate for your files to match each other. You can either enter a specific value or choose from a list of presets.

The conversion may take a while, depending on the complexity, file size and length, and your hardware. Be patient until it finishes, after which you can start importing the media to your CapCut project.

Adjust the Video/Audio Speed

When editing in CapCut, you can try adjusting the speed of your video and audio clips to minimise the audio delay. It’s a quick and convenient way to fine-tune your edits without using any external conversion tools. Below are some steps to follow:

  • Open CapCut on your device and import your video and audio clips to a project if you haven’t already.
  • Tap the Edit icon at the bottom and select the video/audio tracks in the timeline you wish to adjust. You can select multiple at once by tapping on them.

Adjust the Video/Audio Speed

  • Next, tap the Speed icon at the bottom, followed by Normal, and use the slider to increase or decrease the speed. Or tap on the preset values, e.g., 1x, 1x, 2x, etc.
    • On the desktop app, hold and drag the imported track onto the timeline. Then go to the Speed tab in the right-hand panel and use the “Times” slider to adjust the video/audio playback speed to your preference.
  • Preview your changes and tap Apply to save them.

The trick here is to speed up or slow down the audio speed to match the video or vice-versa. You can also use CapCut’s “Extract Audio” feature (or “Separate Audio” on desktop), export it, and then import the audio to a third-party audio-editing software like Audacity ( for making more granular, subtle changes.

Adjust the Audio Track in the Timeline

Another workaround to the audio delay in CapCut is to move the audio track slightly forward or backwards relative to the video. Spread out your edit by zooming into the timeline to make the tracks longer, then bring the audio track by a small increment (around four to ten frames ahead of the video). It’s okay if it doesn’t match the video perfectly.

Once you do this, proceed to export your project and check whether the audio syncs up better with the video now. Remember, it might take a few tries to get the timing just right.

Disable “Proxy” in CapCut (Desktop)

On select hardware configuration, especially if on the lower-end side, CapCut on Windows or macOS automatically enables a feature called “Proxy”, which allows the editor to load an inferior version of the imported content. It improves performance by consuming less system memory (RAM) and processing power (CPU) during the editing.

Some users in the r/CapCut subreddit have found that turning the feature off in the CapCut desktop app solves the audio delay issue. Here’s how:

  • Click the Menu box at the top-left corner of the CapCut window, followed by Settings in the drop-down menu.
  • Navigate to the Performance tab, untick the box for the “Proxy mode…” option, and hit Save.

  • Save any changes you’ve made to your project, close CapCut, and relaunch it.

Now, try exporting your video again via CapCut and see whether it fixes the audio delay.

Update CapCut

Even just a few months earlier, CapCut users (both mobile and PC) had issues getting the audio synced with the video in their exports, which turned out to be a bug CapCut released a patch for in a subsequent version.

You’re likely still using an older app version that exhibits this particular issue. Ensure CapCut is up to date using these steps:

  • iPhone/iPad: Open the App Store, tap your Profile picture on the top-right side and scroll down to the “Updates Available” section. If CapCut is listed there, tap Update next to it.
  • Android: Go to the Play Store, tap your Profile icon next to the search bar, select Manage apps & device, then “Updates available”. Assuming a new version of the CapCut is available, tap the Update button next to it.
  • Windows/Mac: Click the Settings (gear) icon in the upper-right corner of CapCut’s Home page, followed by “Version…” in the context menu. Next, click the “Check for updates” button, and if it returns with a new version, select Install now.

If you face the CapCut audio delay issue even on the most recent version, contact CapCut Support via the app or create a new project to give it one more try before switching to some other editing app (e.g., Premier Rush, Wondershare Filmora, KineMaster, InShot). Also, keep an eye out for future CapCut versions acknowledging the problem and addressing it with a patch.
