XMedia Recode is a powerful, free video editing tool and converter that allows users to easily adjust video volume. Whether you have a video file whose volume is too quiet or you want to reduce loud audio without distortion, XMedia Recode provides professional-grade volume correction tools.
With support for almost all common video and audio formats (MP4, MKV, AVI, MP3, AAC, etc.), you can perform precise decibel changes or automatic peak normalization while maintaining optimal sound quality.
How to Change Video or Audio Volume
Using the volume correction filter, you can permanently modify the sound level of your media files or balance sound across multiple videos.
If you only want to adjust the audio volume of a video, set the Mode to "Copy" under the Video tab. This keeps the video stream bit-for-bit unchanged without losing video quality and finishes the conversion in just a few seconds!
Step-by-Step Guide: How to Adjust Video Volume
In this tutorial, we will show you step-by-step how to permanently fix quiet video sound, boost audio gain, or normalize volume across your files.
Step 1: Select the "Filter/Preview" tab and click the "Audio Track" tab
After opening your video file, navigate to the Filter/Preview tab and select the Audio Track sub-tab. Click the "Add filter" button.
Step 2: Select "Volume correction" filter and click "Add"
From the dropdown menu of audio filters, choose Volume correction and click the Add button to apply it to your current audio track.

Step 3: Choose Volume Correction Method and Adjust Settings
Configure how you want to alter the audio signal: Percentage adjustment, Decibel gain, or Peak Normalization.
Step 4: Activate the Volume Correction Filter
Ensure the filter is active. Clicking the eye icon toggles the Volume correction filter between enabled and disabled status.

Detailed Explanation of Volume Correction Methods
XMedia Recode provides three flexible methods to modify audio volume depending on your specific audio file requirements:
- Volume change (%) – Quick relative percent gain/reduction
- Volume change (dB) – Precise logarithmic decibel amplification
- Volume normalization (dB) – Automated target loudness analysis

1. Volume Change (%)
Adjusting volume in percentages is ideal for quick changes without needing decibel math.
For instance, setting the slider to 200% doubles the volume for quiet clips, while setting it to 50% cuts loud audio in half.

2. Volume Change in Decibels (dB)
Decibel adjustment provides exact logarithmic control over your sound signal.
Adding +3 dB noticeably boosts quiet audio, while +6 dB effectively doubles the signal level. Use this setting when you know precisely how much louder or quieter the audio needs to be.

3. Volume Normalization (dB)
Audio Normalization automatically analyzes the peak and average audio levels of your file and calculates the necessary gain boost or attenuation to match a target volume level in decibels (dB).
This is extremely useful when converting multiple video files from different sources to ensure consistent audio levels across your entire media library.
- Normalize (dB): Defines the target average or peak volume level in decibels.
- Track Volume: Displays the measured audio level of the original file.
- Track gain: Displays the calculated decibel difference required for normalization.

Using the "Analyze" Button:
Clicking "Analyze" scans the entire audio track and determines its exact current peak/average volume, allowing XMedia Recode to calculate precise gain without causing sound distortion or clipping.
