Video editing is as much about editing sounds as it is editing video clips. There's a wide range of sounds you may be looking to add to a video, a list that includes music, sound effects, voiceovers, podcasts, and interviews. Luckily, this is a task that doesn't require heavy-duty video editors like Adobe Premiere or iMovie – you can do it online with Kapwing.

The Kapwing editor enables you to add as many audio tracks as your video needs and specify when exactly each sound appears in the video. You can even grab audio from the internet just by pasting URLs into your Kapwing project.

Here's how to add multiple audio tracks to a video:

1. Upload your video to Kapwing Studio

2. Add your audio tracks

3. Add other elements to your video

3. Export & download

Watch our tutorial for a full walkthrough

1. Upload your video to Kapwing Studio

Head to Kapwing Studio and click "Get Started". Upload your video by searching your files or dragging and dropping it onto the screen. If the video is already on the internet, simply copy and paste its link into Kapwing – this works for URLs from YouTube, SoundCloud, Twitter, TikTok, Vimeo, and other platforms.

2. Add your audio tracks

To add audio tracks to your video, click the "Timeline" button in the top toolbar. Click "Upload" in the left corner and select the audio files you want to bring in (Kapwing currently supports MP3 audio files). If you have a video you only want to use the audio from, head to the Kapwing Converter tool to create an MP3 file from the video before uploading it in the Timeline.

Each added audio file will appear as a layer on the bottom half of the screen in the timeline, which plays the video from left to right. To adjust when in the video an individual audio track is played, drag the ends of the layer to the points where you want it to start and end relative to other elements in the video. If you need more help with navigating the timeline, check out this tutorial.

Take note that audio added in this way through the Timeline stays within the scene where it's uploaded. That is to say, if your project has more than one scene (as displayed on the left side of the main editor screen), audio uploaded to scene one will stop playing as soon as scene two begins.

Each scene has its own Timeline where audio can be uploaded

If you want to add an audio track that will play through the whole video, click the "Audio" tab in the main editor's top toolbar. You can upload an MP3 file, record a voiceover, or paste a link to a video – only the audio will be included in your project! Sounds added here will play through every scene of the video.

Go to the global audio tab to upload audio that will play through the whole video

3. Add other elements to your video

In addition to audio, there are a variety of other edits you can make to your video in the Kapwing editor.

  • Create an audio waveform – Make your audio visual by turning it into an audio waveform. Click "Elements" in the toolbar and selecting "Add a waveform" on the right side.
  • Animate the video – Add some movement to your video with video animations. Click the video layer and explore the options in the "Animate" tab on the right side to include effects like fade, drop in, or hue rotate.
  • Add text  – Click "Text" in the toolbar and use options on the right side to adjust how it looks – you can change the font, color, or even add a drop shadow or animations.
  • Add images and GIFs – Bring images and GIFs into the project using the "Upload" button or by searching for them in the "Images" tab.

To adjust when elements like text, images, and GIFs appear on the screen, click the "Timeline" and drag the ends of the layers to specify their start and end points as you did with audio tracks in the previous step.

3. Export & download

When you're happy with how your video looks, click the red "Export Video" button in the top right corner. After a few moments, your video will be ready for downloading and sharing. To save the video to your computer, click "Download". Share your creation with others by sending them the page's URL or by using the social icons to post to social media.
