Quiet sound in videos on a smartphone is a common problem faced by users Android regardless of the device model. The reasons may be different: from unsuccessful recording at a low volume level to codec features when exporting videos. Fortunately, you can correct the situation both with standard system tools and with the help of specialized applications.

In this article we will examine 7 proven methods increasing the volume in a video - from basic player settings to advanced tools for processing audio tracks. You'll learn how to enhance sound without losing quality, which apps are suitable for beginners, and which offer professional features. We will pay special attention to hidden settings in popular players (for example, VLC or MX Player), which many users overlook.

Important: the methods differ in complexity and effectiveness. If you need to quickly raise the volume by 20-30%, the built-in tools will suffice. To radically improve the sound (for example, when recording from an external microphone), you will need desktop solutions or mobile audio editors. Let's start with the simplest!

1. Increasing the volume through the player settings

Many video players for Android have built-in tools for amplifying the sound, but they are often hidden in the depths of the menu. Let's look at the two most popular applications - MX Player and VLCthat support this function.

The MX Player algorithm works like this:

  1. Open the video in the player.
  2. Tap across the screen to display the control panel.
  3. Click on the icon ⚙️ Settings (gear) in the upper right corner.
  4. Select Audio → Sound amplification.
  5. Move the slider to 150-200% (the maximum is 200%, but distortion may appear).

In VLC the process is slightly different:

  • 🎵 In During playback, swipe up from the bottom panel to open additional settings.
  • 🔊 Find the speaker icon with a slider Audio gain (usually on the right).
  • 📈 Set the value from +10 dB up to +20 dB (higher is the risk of wheezing).

Both players support saving settings for a specific file, so you don’t have to adjust the gain again each time. However, remember: excessively increasing the volume can lead to sound distortion, especially if the source file is recorded with a low bitrate.

💡

If after amplification the sound becomes “raucous”, try reducing the value by 10-15% or enable the “Audio Normalization” option in the player settings (if yes).

2. Using the Android system equalizer

Some firmware Android (for example MIUI, ColorOS, One UI) have a built-in equalizer that can be applied to all played sounds, including video. This feature is often hidden, but it takes less than a minute to activate.

How to enable:

  1. Go to Settings → Sound and vibration → Sound quality (names may vary).
  2. Activate the switch Equalizer or Audio effects.
  3. Select preset Bass or Volume (increases midrange and treble).
  4. Manually raise the sliders by 100-300 Hz and 1-3 kHz to enhance voice and music.

If your firmware does not have a built-in equalizer, install a third-party application, for example:

  • 🎛️ Equalizer FX —a simple equalizer with presets for music and speech.
  • 🔊 Music Volume EQ —supports separate settings for each application.
  • 📱 Wavelet —an advanced tool with frequency correction and virtual surround.
⚠️ Attention: On some devices (for example, Google Pixel or Samsung s One UI 5+), the system equalizer may conflict with third-party players. In this case, use either the built-in player or disable system audio effects in the settings.

3. Applications for enhancing sound in video

If the built-in tools are not enough, specialized applications will come to the rescue. They allow you not only to increase the volume, but also to improve sound quality through noise reduction, normalization and other effects. Let's look at the top 5 solutions for Android.

Application Max. gain Additional functions Free version
InShot up to +30 dB Noise reduction, equalizer, music overlay Yes (with watermark)
KineMaster up to +20 dB Multi-track editing, reverb effects Yes (export restrictions)
VideoShow up to +25 dB Automatic normalization, deletion noise Yes
PowerDirector up to +18 dB Professional audio filters, 4K support Yes (with logo)
Lexis Audio Editor up to +40 dB Specialized audio editor with support for VST plugins No (paid)

For most tasks, InShot or VideoShowis enough. If you need professional editing (for example, for YouTube or TikTok), pay attention to KineMaster or PowerDirector. The last two support working with multiple audio tracks, which is useful when overlaying music on a video.

Instructions for enhancing sound in InShot:

Import video into the project|Tap on the track with audio|Select "Volume"|Move the slider to the right (max. +30 dB)|Export video with quality 1080p-->

⚠️ Attention: When the sound is amplified by more than +20 dB, background noise (for example, hissing or crackling) may appear in cheap microphones. To avoid this, use the noise reduction function in the same InShot or VideoShow.

4. Sound normalization via PC (maximum quality)

If you are working with important videos (for example, for a blog or presentation), processing on a computer will give the best result. apps like Audacity (free) or Adobe Audition (paid) are suitable for this. Let's look at the process using an example Audacity:

Steps to enhance sound:

  1. Export the audio track from the video (you can use VLC: Media → Convert → Select video → Audio - MP3).
  2. Open the file in Audacity.
  3. Select the entire track (Ctrl+A) and apply the effect Normalize (value -3 dB for safety).
  4. Add Compressor (settings: threshold -20 dB, ratio 3:1) to equalize the volume.
  5. Export the processed audio and replace it with the original track in the video (for example, through Shotcut or OpenShot).

Advantages of this method:

  • 🎧 Without loss of quality —processing is carried out in high resolution (up to 32-bit float).
  • 🔧 Fine tuning - you can remove noise, highlight the voice, add effects.
  • 📁 Support batch processing - enhance the sound in dozens of files at a time.

If you do not have access to a PC, similar functions are available in the mobile version Audacity (application Audio Evolution Mobile), but the interface is less convenient.

What to do if, after normalization, the sound becomes “flat”?

This is due to excessive compression. Try reducing the compressor threshold to -25 dB or use a dynamic equalizer to restore high frequencies. In Audacity an effect is suitable for this Graphic EQ with a rise of 10-12 kHz 3-5 dB.

5. Amplifying sound when recording video (problem prevention)

It is better to prevent quiet sound than to amplify it later. If you often shoot video on your phone, pay attention to the recording settings and external accessories.

Tips for improving sound to filming:

  • 🎤 Use an external microphone - even budget models (for example, Boya BY-M1 or Rode VideoMicro) give an increase of 2-3 times compared to the built-in microphone.
  • 📱 Activate "Microphone Boost" in the camera (there is c Google Camera or Open Camera).
  • 🔇 Remove the cover —it can muffle the microphone (especially important for Samsung Galaxy i Xiaomi).
  • 📍 Move your phone closer to the sound source —the volume drops quadratically with distance.

The app Open Camera (free, open source) has hidden settings to improve audio:

  1. Open Settings → Other camera settings.
  2. Find the option Audio recording and select High quality (AAC 192 kbps).
  3. Activate Noise reduction (if available).
  4. In the section Video set the audio bitrate to maximum (320 kbps).

To check the sound level during recording, use the application Decibel X —it shows the current volume in decibels. Optimal range for speech: 60-70 dB.

6. Online services for sound amplification (without installing apps)

If you do not want to install applications, you can use online tools. They work directly in. browser, but have file size restrictions (usually up to 500 MB) and require a stable Internet connection.

Top 3 services:

  • 🌐 MP3Louder - amplifies sound up to +20 dB, supports MP4, MOV, AVI.
  • 🎵 AudioAlter — normalizes volume and removes noise.
  • 📹 Clideo —simple interface, export to Full HD.

Instructions for MP3Louder:

  1. Upload video from your phone or Google Drive.
  2. Select gain level (+10 dB to begin with).
  3. Click Boost Volume and wait for processing.
  4. Download the result or save to the cloud.
⚠️ Attention: Online services can save downloaded files on their servers (even if they promise to delete them). Do not download confidential videos. For sensitive data, use offline solutions.

The advantage of online tools is cross-platform: you can amplify the sound even on iPhone or Windowsif you don’t have a device at hand. Android-devices.

7. Manual editing via ADB (for advanced users)

This method is suitable for those who are ready to work with the console and have root access or an unlocked bootloader. It allows you to change system audio settings. but risky - incorrect commands can lead to failures.

How to enhance sound through ADB:

  1. Connect your phone to the PC and activate USB debugging (Settings → About phone → Build number (7 taps) → For developers → USB debugging).
  2. Open the command line and enter: 
    adb shell settings put system media_volume_steps 30

    This increases the number of volume control steps.

  3. To increase the maximum volume control, use: 
    adb shell settings put global volume_steps 15
  4. Restart the device.

For devices with root you can edit the file /system/etc/audio_policy_configuration.xml, but this requires knowledge XML and backup.

⚠️ Attention: Changing system audio settings can lead to distortion of the sound in headphones or speakers. Before experiments, create a backup via TWRP or Titanium Backup.
💡

Methods via ADB or root are only suitable for experienced users. online services.
