Adding audio to a video in Reaper is a straightforward process. You can download Reaper from the official Reaper website. Once you have it installed, you can follow the steps to get you started ​💡

✅ 1. Install VLC Player

Reaper uses VLC for video playback, so make sure you have it installed on your computer. You can download VLC from the official VLC website.

✅ 2. Open Reaper

Launch Reaper and create a new project by going to

File > New Project

✅ 3. Import the Video

Drag and drop your video file into the Reaper timeline. Alternatively, you can go to

Insert > Media File

and select your video file. You should see the video track appear in the timeline.

✅ 4. Add Audio

Drag and drop your audio file into the timeline. You can place it on a separate track below the video track. If you need to import multiple audio files, repeat this step for each file.

✅ 5. Sync Audio and Video

Adjust the position of the audio track to sync it with the video. You can use the zoom function (by scrolling with your mouse wheel) to get a closer view of the timeline for precise alignment. The snap function (enabled by default) helps you align the audio with the video frames.

✅ 6. Edit as Needed

You can edit the audio and video tracks as needed. This includes cutting, trimming, and adding effects. To cut or trim, select the item and use the Split tool (press S on your keyboard) or drag the edges of the item. To add effects, click on the FX button on the track control panel and choose the desired effects from the list.

✅ 7. Render the Final Video

Once you're satisfied with the sync and edits, go to

File > Render

In the render dialog, choose the video format (e.g., MP4), size, and frame rate. Make sure to select the appropriate audio settings as well. You can also choose the output directory and file name.

✅ 8. Save the File

Click Render to save the final video with the new audio track. The rendering process may take some time depending on the length and complexity of your project.
