You shot an excellent video on your smartphone, but the sound turned out to be quiet, noisy, or completely inaudible? The problem is familiar to many: even flagship Androiddevices often record audio worse than the picture. The reasons are different - from a cheap microphone to incorrect camera settings. Fortunately, you can correct the sound both before shooting (prevention) and after (processing).

In this article we will look at 7 proven methods improving the sound on video directly on your phone - from basic tricks with settings to advanced applications for noise reduction and equalizer. It doesn’t matter whether you’re shooting for YouTube, TikTok or just want to save memories with clear sound - these methods will work on any Androidsmartphone (from budget Redmi to top-end Samsung Galaxy S23).

Spoiler: for most tasks you do not need a computer or expensive software. All tools are free (or with free versions) and are available in Google Play. And if you are willing to spend 5-10 minutes on setup, the result will exceed your expectations: the voice will become clearer, background noise will disappear, and the bass will add cinematic quality to the video.

1. before shooting: how to avoid sound problems

The best way to improve the sound is don't ruin it in the first place. Most problems (low voice, wind noise, echo) occur due to incorrect microphone settings or shooting conditions. Here's what you need to check to the way you pressed "Record":

  • 🎤 Turn off noise reduction in the camera. In most stock applications (for example, Google Camera or Samsung Camera) there is an option “Sound enhancement” or “Noise reduction”. c Camera Settings → Sound.
  • 🌬️ Use wind protection. Even a light wind on the street creates an unpleasant “gurgling” noise. If you don’t have a professional fluffy microphone case, put a thin sock on your smartphone (seriously, this is). works!) or shoot a video indoors.
  • 📱 Check which microphone is active. On many smartphones (for example, Xiaomi or OnePlus) when you connect headphones with a microphone, audio is recorded from them, and not from the built-in microphone. Make sure that nothing is connected to it. connector 3.5 mm or USB-C.
  • 🔇 Disable notifications. Sounds of messages or calls will ruin the recording. Switch your phone to Do Not Disturb mode or turn on Airplane Mode before shooting.

If you are filming an interview or monologue, keep your smartphone as close as possible to the sound source (but not closer than 20-30 cm, otherwise the “proximity” effect will occur - the voice will become too bassy). For the best result, use external microphone (even a budget one Lavalier for 500–1000 ₽ will increase the quality by 2–3 times).

⚠️ Attention: On some smartphones (for example, Pixel or Oppo) there is a “Stereo Sound” option in the camera settings. Enabling it may worsen voice intelligibility. in noisy conditions - turn it off if you are filming in crowded places.

For most users, the optimal choice will be Open Camera - it is free, easy and allows you to manually set audio bitrate (set 192–256 kbps to balance quality and file size). If you need advanced functions (for example, connection Rode VideoMic), pay attention to Filmic Pro.

How to set Open Camera for better sound:

  1. Open the application and go to Settings → Video format.
  2. In the "Audio" section, select Bitrate: 256 kbps i Format: AAC.
  3. Activate the option Use external microphone (if connected).
  4. Turn on Sound stabilization (reduces volume jumps).
💡

If you shoot on Samsung Galaxy, try the application Camera MX —it works better with the brand’s built-in microphones and supports the format Dolby Digital on some models.

3. Improving sound after shooting: top 5 applications for processing

If the video has already been shot and the sound leaves much to be desired, do not despair using mobile applications. you can:

  • 🔊 Increase the volume without distortion;
  • 🎛️ Remove noise (wind, background music, hum);
  • 🎤 Highlight voice against the background of other sounds;
  • 🎵 Add equalizer for bass/treble.

Here are the best tools for Android:

1. Lexis Audio Editor (for precise processing)

Professional audio editor with support multi-track processing. Allows you to cut pauses, normalize volume and apply effects (reverb, compression). noise (for example, clicks or creaks).

Key feature: tool Spectral Editing — visual removal of noise (for example, clicks or squeaks).

2. AudioLab (for quick improvement)

An application with presets for different scenarios:

  • «Clear voice" - removes echo and noise;
  • «Bass booster" - adds low frequencies;
  • «Normalization" - evens out the volume.

Minus: free version remains a watermark.

3. Dolby On (for automatic improvement)

Developed by Dolby especially for mobile devices. Automatically analyzes audio and applies:

  • Noise reduction;
  • Voice enhancement;
  • Spatial sound (effect Dolby Atmos).

Important: works only with video up to 1080p.

4. WaveEditor (for equalizer)

If you need to fine-tune the frequencies (for example, remove hiss or add bass), this editor offers 10-band equalizer and effects (reverb, delaySupports formats MP3, WAV, AAC.

5. CapCut (for editing + sound)

Popular video editor with built-in tools for audio:

  • Automatic noise removal;
  • Synchronizing sound with video;
  • Library of free sound effects.

Ideal if you need not only to improve the sound, but also to edit video.

Make sure that the source file is not compressed (it is better to work with .MP4 or .MOV)

Make a backup copy of the original

Disable other applications (so as not to interrupt processing)

Check the free space (processing requires up to 2x file size)-->

4. How to remove noise from video on Android: step-by-step guide

One of the most common defects is background noise (wind, air conditioner hum, street thunder). You can remove it using the application Lexis Audio Editor or AudioLab. Let's look at the process using an example Lexis:

  1. Import video

    Open the application, click Open file and select the video. The application will automatically extract the audio track.

  2. Select the noise

    Find the area where only noise is heard (without the voice). Select it and click Effects → Noise Reduction → Noise Sample.

  3. Apply filter

    Go back to the beginning of the track, select Effects → Noise Reduction → Apply. Adjust the intensity (we recommend 70–85% -more may distort the voice).

  4. Normalize the volume

    Go to Effects → Normalize and set the target volume to -3 dB (this will prevent clipping).

  5. Export the result

    Click Save and select format MP3 (for compatibility) or WAV (for better quality).

Critical nuance: if the video contains music or important background sounds (for example, birdsong), aggressive noise reduction will distort them. In this case, use the tool Spectral Editing to do targeted noise removal. Lexis for targeted noise removal.

For a quick result will do Dolby On:

  1. Import the video into the application.
  2. Select the style “Voice" or "Music».
  3. Activate the option "Remove noise».
  4. Export with quality "High».
⚠️ Attention: When processing long videos (from 30 minutes), close all background applications On weak smartphones. (for example, Redmi 9A) processing may be interrupted due to lack of memory.

5. Voice enhancement: how to make speech clearer

If the voice in the video is too quiet or “muffled” by background sounds, this will help compression and equalization. These tools highlight human speech, making it louder and more intelligible. Let's consider two methods:

Method 1: Compressor c WaveEditor

The compressor reduces the difference between loud and quiet sounds, “pulling” the voice to the overall level.

  1. Import the audio track into WaveEditor.
  2. Go to Effects → Compressor.
  3. Set parameters:
    • Threshold: -20 dB
    • Ratio: 4:1
    • Attack: 10 ms
    • Recovery (Release): 100 ms
  • Apply the effect and listen to the result.

    • Method 2: Equalizer in AudioLab

    The human voice is in the range 80 Hz - 4 kHzAmplifying these frequencies, you can make speech clearer:

    1. Open the track in AudioLab.
    2. Select Equalizer → 10-band.
    3. Raise sliders to:
      • 200 Hz (for the “body” of the voice);
      • 1–2 kHz (for intelligibility);
      • 10 kHz (for “air”).
  • Reduce 60–80 Hz (to remove hum).

    • To automate the process, use the preset "Clean voice" in AudioLab or "Speech Enhancement" in Lexis Audio Editor.

    What to do if the voice sounds like it is coming from a barrel?

    This effect occurs due to reverberation (echo) in the room. To remove. it:

    1. In Lexis Audio Editor apply the effect De-reverb (in the section Effects → Recovery).

    2. Set the parameter Intensity to 60–70%.

    3. If the echo is strong, additionally use Noise reduction with a sample of silence (record 2-3 seconds of silence in the same room).

    6. Add effects: reverberation, bass, spatial sound

    Sometimes the sound needs to be not just “fixed”, but made more expressive. For example, add dimensionality for music videos or bass for dynamic videos. Here's how to do it:

    Reverb (Reverb)

    Creates a “room” effect - the voice sounds as if it was recorded in a studio or hall. Suitable for music videos or voiceovers.

    How to add to WaveEditor:

    1. Select track and go to Effects → Reverb.
    2. Select a preset:
      • Small Room — for natural sound;
      • Concert Hall — for volume;
      • Plate — for bright “metallic” effect.
  • Adjust Decay Time (decay time) - enough for voice 1.5–2.5 sec.

    • Bass boost

    For dynamic videos (sports videos, tiktoks) you can add low frequencies. Use the equalizer in AudioLab:

    • Raise the sliders to 60–100 Hz (bass) and 200–300 Hz (lower mid).
    • Reduce 500–800 Hzto avoid muddy sound.

    Spatial sound (Dolby Atmos)

    If your smartphone supports Dolby Atmos (for example, Samsung Galaxy or Xiaomi 13), turn it on in the sound settings (Settings → Sound → Quality and Effects → Dolby Atmos). For video, use the "Cinema" or "Music».

    To apply the effect to an already shot video, use Dolby On:

    1. Import file.
    2. Select the style "Cinema».
    3. Activate the option "Spatial sound».
    💡

    Do not overdo it with effects Too much reverb or bass will make the sound! unnatural. Always check the result on different devices (headphones, speaker, phone).

    7. Saving and exporting: formats and settings for better quality

    After processing the audio, it is important to save the file correctly so as not to lose quality:

    Audio formats

    For video on Android two formats are optimal:

    • AAC - balanced quality and size (bitrate 192–320 kbit/s).
    • WAV - lossless, but large size (suitable for further processing on PC).

    Avoid MP3 with a lower bitrate 128 kbps - the sound will be “flat”.

    Export settings

    When saving in applications, pay attention to:

    • Bitrate: minimum 192 kbps for AAC.
    • Volume: target level - -3 dB (avoid clipping).
    • Channels: Stereo (if the source is stereo) or Mono (for voice).

    How to combine processed audio with video

    If you processed the audio separately, use CapCut or KineMaster:

    1. Import the video and audio file.
    2. Delete the original audio track from the video (in CapCut: click on the clip → "Separate audio" → delete the track).
    3. Add processed audio to the timeline and sync.
    4. Export to MP4 with settings:
      • Resolution: original;
      • Bitrate video: 10–20 Mbit/s;
      • Audio bitrate: 320 kbit/s.
    ⚠️ Attention: When exporting to CapCut free version adds a watermark. To remove it, use KineMaster (the watermark appears only when exporting to 4K) or OpenShot (completely free).

    FAQ: Frequently asked questions about improving sound on video

    Is it possible to improve the sound on a video shot on an old Android (for example, on Samsung Galaxy J5 2016)?

    Yes, but with reservations. On weak smartphones:

    • Use light applications (Open Camera for shooting, AudioLab for processing).
    • Process the video in short fragments (5-10 minutes each) to avoid glitches.
    • Export to MP3 128 kbit/s —higher bitrates may cause lags.

    If the phone is very slow, transfer the video to a PC and process it there (for example, in Audacity).

    How to remove echo in a video shot in a large room?

    Echo (reverberation) is removed using:

    1. Noise reduction (in Lexis Audio Editor select effect De-reverb).
    2. Equalizer: reduce frequencies 200–500 Hz (where hum accumulates).
    3. Compressor low Release (10-30 ms).

    If the echo is strong, try re-recording the voice separately in a quiet room and overlaying it on the video in editor.

    Which application is better for improving your voice in TikTok?

    For TikTok the following are suitable:

    • CapCut — built-in tools "Improve voice" and "Remove noise»;
    • Dolby On — preset "Social networks" is optimized for short videos;
    • AudioLab — preset "TikTok voice» (boosts high frequencies for intelligibility).

    Tip: TikTok has a built-in tool "Improve sound" (in the video editor it automatically normalizes the volume, but often cuts). bass - use it only for quick edits.

    Why did the sound become robot-like after processing?

    This is due to:

    • Too aggressive noise reduction (reduce intensity to 50–60%);
    • Excessive compression (install Ratio: 2:1 instead of 4:1);
    • Incorrect bitrate when exporting (use 192–320 kbit/s).

    To fix, return to the original file and repeat processing with softer settings.

    Is it possible improve the sound in a video where the voice is barely audible?

    Yes, but the result depends on the noise level:

    1. Use normalization (target level: 0 dB).
    2. Apply compressor low Threshold (-30 dB).
    3. Amplify the frequencies 1–3 kHz (where is voice).
    4. If the noise is strong, try iZotope RX (there is a mobile version) - it restores barely audible speech.

    If the voice is still unintelligible, consider dubbing it (record the voice separately and overlay it on video).
