How to Dub an ASMR Video – Add a Perfect Sound to Your ASMR Video

Not all video creators have professional equipment or recording environment to make an ASMR video, accidents usually happen whether you want it or not. For example, a car passing over the street, you cat knocking over your furnishings, microphone not working for no reason, or you are just not very satisfied with a part of recorded sound. As we all know, a sudden rising voice or noise can totally ruin the experience of your audience. So how to fix it?

Of course, you can choose to re-make those parts, or just delete them, but there is an alternative. You can add a post-recording sound to replace the original seamlessly, which will make your ASMR video more professional, and it’s time-saving. And in this guide, I will show you how to dub your ASMR video with just a simple video editor.

How to Dub an ASMR Video – Step by Step Tutorial

Many video editors in the market can do this job, like Windows Movie Maker, iMovie, VitualDub, etc., since I use Filmora, I will show you how to add/replace audio in this video editing tool, but you can apply these skills in other video editing programs. Let’s begin:

Step 1: Import the video file into the program

First of all, open the video editor, and choose Full Feature Mode. Import the video footage you want to edit into the program. Go Import > Import Media File, locate the video footage, hit Open, and the video file will be immediately imported.

Now, drag and drop the video file into the timeline for advanced editing.

Step 2: Detach the unwanted audio

Now, preview the video file by hitting the Space key, don’t forget to put on out headphone to better recognize the voices (you can also use the playhead to jump to a certain point in the video). Hitting the Space key again to give it a pause when you find the section which needs to be corrected. Now, place the playhead in the exact position where the part begins and click the Split icon (the little scissor icon), and perform the same action at the other end:

This step is to separate the “bad” parts from good parts, and the audio editing won’t affect on good parts.

Right click on the split part, and choose Audio Detach (Ctrl + Alt + D):

Then, there will be audio file added to the audio track, this is the very file detached from this part of video. Right click on it and choose Delete, or you can hit the little trash bin icon the delete it.

Now, when you play the video again, you will find that only this part is soundless.

Step 3: Add/Record new audio file

You can keep it inaudible, but it will can be odd. So, it’s better to dub it with great sound.

Hit the Record a Voiceover at the bottom of the preview window:

Check you input and output settings, hit OK, and the recording will be started in 3 seconds:

Now, it’s time to make your dubbing, like whispering, microphone brushing, scratching, or stroking. An audio file will be generated to go with the video in the timeline.

Hit Space bar to stop the recording. You can trim the audio file if it is too long by dragging the end of the video clip from right to left.

Here I suggest you to try several times, because it takes some time to match the original tone.

If you find that the volume is too high or too low, you can adjust it by double clicking the audio file to open the basic audio editing panel. It also offers a Denoise feature which allows you to remove background noise, but I don’t think it has much effects.

Step 4: Preview and export

Preview the video from beginning to end to see if the dubbed audio files match the orginal video well. Then, hit Export and choose an output format you want. For videos, we usually choose MP4, and you can save it as an audio file by choosing MP3 format.

Bingo! The raw video becomes adorable. Just enjoy it or share it to YouTube to help people have a good sleep!
