Adding sound effects to a video will immediately enhance the video to the next level. Imagine a horror laughter sound to make your spooky video creepier, or a sizzling sound for a steak grilling video. Plus, many video editors also packed with an audio editor to apply sound FX to modify the sound, such as creating audio reverb, boosting bass, or changing the pitch.
You can use video editing software or online tools to add sound effects to a video on Windows, Mac, and mobile phones. The methods are more or less the same:
- For sound effects clips, you simply drag that sounds to the timeline, nudging it to the point you want it to occur with the video. The video editing tools recommended below come with stock sound effects to use for free.
- For morphing the sound of the video, you can select a section of the audio, and apply effects, equalizer or using other tools to adjust the audio. You can change pitch, boost bass, create audio panning, and so on.
We will use tools designed for different editing skill levels as examples. Once you get the hang of it, you can use any tool you are familiar with. Beginners or pro, you can resort to our recommendation of best video editors with sound effects and start to spice up your video.
How to Add Sound Effects to a Video with PowerDirector
PowerDirector is a timeline based video editing software, developed by Cyberlink. It is loaded with free stock sound effects for you to use instantly. Let's see how it works step by step.
Step 1. Create a new project from Menu > File > New Project. Select a folder to store your project, or creating a new folder on your disc. For instance, you can create a folder named CyberLink project 1. Then enter the name for the project video, such as Birthday party 2021.
Step 2. Import video clips and music you like to edit into the Media content bin.
Step 3. Click the first icon on the left panel, and go to sound clips.
Step 4. Browse sound effects by themes, such as weapons, instruments, animals, environment, etc. Double click to listen to the sound, and hit the download icon if you love that piece.
Step 5. Drag the downloaded sound clip and drag it to the timeline. Place it on the audio track under the video.
Step 6. Play the video and stops at the place you want the sound to enter. You can enlarge the timeline (Ctrl+Mouse scrolling), and add sounds at a more precise position, see tips below.
Step 7. Finish editing other aspects of the video, and click the Produce Tab on the top to export the video.
Tip 1: Precisely Add Sound Effects to Hit the Right Timing
Cover your mouse on the timeline, and when you see a clock icon, drag it to enlarge the timeline all the way to the extreme (or you can use Ctrl+mouse scrolling).
Now when you move the playhead, you can feel that it is moved frame by frame. With this degree of precision, you can stop at the exact frame when you want the sound effects to occur, such as a gunshot corresponding to the moment shortly after the man pulls the trigger (sound travels slower than light).
Tip 2: Split Sound Clips to Keep the Portion You Want
The sound clips we added might be longer than we want. In such a case, you can split the sound, and delete the portion you no longer need. Please also enlarge the timeline before splitting the audio for precision.
Tip 3: Press Alt+Mouse Scrolling to View Tracks Underneath.
For instance, if you are using video templates, there might already be background music added to the video. Sometimes, the music is placed on track 6, and you cannot see it in the first three or four rows of the tracks. The result is, you hear music playing, even louder than the sound effects you just added, yet you cannot find where the music is, let alone mute it or lower its volume.
Tip 4: Apply Sound Effects to Music and Voiceover
Besides using standalone voice changer software, you can also alter the voice into a robot's voice using the audio editor in Cyberlink PowerDirector.
- Right-click on the audio clip and select Edit Audio > Audio Editor.
- Go to Vocal Transformer, and use the preset Robot. You can also use Child, Duck, Man and Woman sounds, or dial the pitch for a custom sound.
For advanced users, there are other tools to add Sound FX on the left panel, including equalizer, reverb, compressor, and the function to remove noise.

Let's say you want gunshot sound effects to play when a person pulls the trigger in the video, with the bar connect the gunshot sound and the video, you only need to find the timing for once, and will never need to worry about syncing the A/V when you move the video.
Step 6. Click on an audio clip, and hit the wave-shaped icon above the monitor window. Select a sound effect (sound FX) from the drop-down menu of the equalizer.
For instance, you can boost or reduce the bass or treble of the sound clips.
