Using VLC Media Player: Open VLC, load MP4, go to Tools > Effects > Audio tab, adjust settings
Adjusting the sound on an MP4 file can be easily accomplished using VLC Media Player, a versatile and widely-used media player. To begin, open VLC Media Player on your computer. If you don’t have it installed, you can download it for free from the official VLC website. Once VLC is open, load your MP4 file by clicking on Media in the top-left corner, then selecting Open File. Navigate to the location of your MP4 file, select it, and click Open to start playback.
With your MP4 file playing in VLC, the next step is to access the audio adjustment settings. Go to the top menu and click on Tools, then hover over Effects and select Audio Effects from the dropdown menu. This will open a new window titled Adjustments and Effects, where you can fine-tune the audio settings for your MP4 file. The Audio Effects window is divided into several tabs, but for sound adjustments, focus on the Audio tab.
In the Audio tab, you’ll find a range of options to modify the sound of your MP4 file. The Gain slider allows you to increase or decrease the overall volume. If the audio is too quiet, slide it to the right to amplify the sound; if it’s too loud, slide it to the left. Below the Gain slider, you’ll see an Equalizer section, which lets you adjust specific frequency bands to enhance or reduce certain aspects of the audio, such as bass or treble. Click on the Enable checkbox to activate the equalizer and then adjust the sliders to your preference.
Additionally, the Audio tab includes a Compressor option, which can help normalize the audio levels, making soft sounds louder and loud sounds quieter. Enable the compressor by checking the box and adjust the ratio and threshold settings to achieve the desired effect. Experiment with these settings while the MP4 is playing to hear the changes in real-time. Once you’re satisfied with the adjustments, click Close to save your changes and continue playing the file with the updated audio settings.
For more advanced users, VLC also offers a Spatializer and Stereo Width options in the Audio tab, which can alter the spatial characteristics of the sound. The Spatializer adds a 3D effect to the audio, while the Stereo Width adjusts the separation between the left and right channels. These features can be particularly useful for enhancing the listening experience, especially when using headphones or external speakers. By following these steps in VLC Media Player, you can effectively adjust the sound on your MP4 files to suit your preferences.

Adobe Premiere Pro: Import MP4, drag to timeline, use Audio Effects panel to modify volume, EQ, etc
Adobe Premiere Pro is a powerful video editing software that allows you to import and manipulate MP4 files with ease, including adjusting audio to enhance your project. To begin, launch Premiere Pro and create a new project or open an existing one. Navigate to the 'File' menu and select 'Import' to browse for your MP4 file. Once located, click on the file and it will appear in the Project panel. From here, you can simply drag and drop the MP4 file onto the timeline, which is the central area where you arrange and edit your video and audio clips. This process is straightforward and ensures your media is ready for editing.
With your MP4 file on the timeline, you can now focus on audio adjustments. Premiere Pro offers a comprehensive set of tools for this in the Audio Effects panel. To access this, go to the 'Window' menu and ensure 'Audio Effects' is selected. The panel will open, revealing various effects and controls. Here, you can modify the audio in multiple ways.

The Audio Effects panel also provides more advanced options for fine-tuning your audio. For instance, you can improve the overall sound quality by applying equalization (EQ) effects. Drag the 'Parametric Equalizer' effect onto your clip and adjust the frequency bands to enhance or reduce specific tones. This is particularly useful for removing background noise or emphasizing certain audio elements. Additionally, effects like 'Compressor' and 'Limiter' can help control dynamic range, ensuring consistent audio levels throughout your MP4.
Premiere Pro's audio editing capabilities extend further with various other effects. You can add reverb to create a sense of space, use noise reduction tools for cleaner audio, or apply special effects like echo and flanger for creative purposes. Each effect offers customizable parameters, giving you precise control over the sound. Experimenting with these tools can significantly enhance the audio quality and overall impact of your MP4 video.
After applying the desired audio effects, it's essential to review your work. Play the clip on the timeline to ensure the adjustments meet your expectations. You can always go back and tweak the settings or add more effects. Once satisfied, remember to save your project. Adobe Premiere Pro's intuitive interface and robust audio tools make it an excellent choice for anyone looking to adjust and refine sounds in their MP4 videos.

Windows 10 Tools: Use Movie Maker or Photos app to import MP4, adjust audio volume or mute
Windows 10 offers built-in tools that allow you to import MP4 files and adjust their audio settings, such as volume or muting, without the need for third-party software. Two primary tools for this purpose are Windows Movie Maker (available through the Windows Essentials 2012 suite) and the Photos app, which includes basic video editing features. Below is a step-by-step guide on how to use these tools to adjust sounds on MP4 files.
Using Windows Movie Maker to Adjust Audio in MP4 Files:
First, ensure you have Windows Movie Maker installed. Since it’s no longer available for download from Microsoft, you may need to install it from a trusted source or use the Windows Essentials 2012 suite. Once installed, open the application and click on “Add videos and photos” to import your MP4 file. Drag the file to the timeline at the bottom of the screen. To adjust the audio volume, click on the “Edit” tab and select “Video volume”. A volume slider will appear, allowing you to increase or decrease the audio level. If you want to mute the audio entirely, drag the slider all the way to the left or use the “Mute” option. Once done, save your project by clicking “File” > “Save movie” and choose the desired quality and format.
Using the Photos App to Adjust Audio in MP4 Files:
The Photos app in Windows 10 is a simpler alternative for quick audio adjustments. Open the app and click on “Import” to add your MP4 file. Once imported, select the video and click on the “Edit & Create” button in the top menu, then choose “Trim”. Although primarily for trimming, this feature also allows you to adjust audio. Play the video and use the volume slider at the bottom of the screen to increase or decrease the audio level. To mute the audio, simply drag the volume slider to zero. After making adjustments, click “Save a copy” to export the modified video without overwriting the original file.
Additional Tips for Both Tools:
When using Windows Movie Maker, you can also apply fade-in or fade-out effects to the audio for smoother transitions. In the Photos app, while the audio adjustment options are limited, it’s ideal for quick fixes without the need for additional software. Both tools are user-friendly and require no technical expertise, making them suitable for beginners.
Exporting and Saving Your Adjusted MP4 File:
After adjusting the audio in either tool, ensure you save the file in the desired format and quality. In Windows Movie Maker, you can choose from various resolutions and file types under the “Save movie” options. In the Photos app, the “Save a copy” feature automatically saves the file in MP4 format, preserving compatibility with most devices and platforms. Always review the final output to ensure the audio adjustments meet your expectations before finalizing the export.
By leveraging these Windows 10 tools, you can easily import MP4 files, adjust audio volume, or mute sounds without the need for complex software. Whether you prefer the versatility of Windows Movie Maker or the simplicity of the Photos app, both options provide straightforward solutions for managing audio in your video files.

Mobile Apps: Download InShot or VN Editor, import MP4, use audio tools to tweak sound
If you're looking to adjust the sound on an MP4 file directly from your mobile device, two highly recommended apps are InShot and VN Editor. Both apps are user-friendly and offer robust audio editing tools that allow you to tweak sound levels, add effects, and more. Start by downloading either InShot or VN Editor from the App Store (iOS) or Google Play Store (Android). Once installed, open the app and navigate to the import or create project option. Select the MP4 file you want to edit from your device’s gallery or file manager. The app will load the video, and you’ll be able to access the audio editing features.
After importing your MP4 file, locate the audio editing tools within the app. In InShot, you can find these tools by tapping the "Volume" or "Sound" icon, usually represented by a speaker symbol. In VN Editor, the audio controls are often available in the timeline or a dedicated audio settings menu. Both apps allow you to adjust the overall volume of the audio track by dragging a slider or inputting a specific value. This is the simplest way to make the sound louder or quieter, depending on your needs.
Beyond basic volume adjustments, both InShot and VN Editor offer advanced audio tools to fine-tune your MP4’s sound. You can trim the audio to remove unwanted sections, fade the sound in or out for smoother transitions, or even extract the audio entirely for separate editing. InShot often includes features like background music addition, voiceovers, and sound effects, while VN Editor may provide more precise control over audio timing and synchronization with video elements. Experiment with these tools to achieve the desired sound quality.
To further enhance your MP4’s audio, explore the apps’ built-in effects and filters. InShot frequently offers options like equalizer settings, where you can adjust bass, treble, or apply presets for different audio styles. VN Editor might include noise reduction tools to minimize background interference or audio enhancers to improve clarity. These features are particularly useful if the original audio quality is poor or if you’re aiming for a specific sound aesthetic.
Once you’ve finished adjusting the sound, preview your changes within the app to ensure everything sounds as intended. If you’re satisfied, export the edited MP4 file by selecting the export or save option. Both InShot and VN Editor typically allow you to choose the output resolution and format before saving the file to your device. With these mobile apps, adjusting sounds on an MP4 becomes a straightforward and accessible task, even for beginners.
