Video Volume Booster

Recorded a video that's too quiet? Give its sound a lift before you share it. Video Volume Booster helps you increase video volume, listen to the difference and save a louder MP4 copy, while your original stays untouched. Bring up the sound in an interview, a recorded lesson or a personal clip with audio that's hard to hear. Choose your video and adjust the audio gain until the sound suits your clip. Pick a preset for a quick starting point or enter a precise value from -24 dB to +40 dB. You can also lower the volume or mute the audio. Peak protection helps keep strong peaks under control, though it can reduce the effective boost when a recording is already loud. Hear your changes before exporting. Switch between Original and Processed at the same position, move to the part you want to check or loop a listening interval to compare it again. The loop is just for listening; your exported video still includes the full clip. If you're unsure where to start, analyze the audio and review the gain suggested by peak normalization before applying it. When you're happy with the sound, export a separate video with the adjusted audio. Save the completed copy to Files, play it back or share it through your chosen app. Exports have no fixed 30-second cutoff and no added watermark. The time and space needed depend on your video and device. Working through several recordings? Add multiple videos and prepare them with shared settings or adjust each clip individually. The export queue processes them one at a time, and you can cancel the current export or the remaining jobs separately. Your projects remember your adjustments, so you can return to them later. Save your favorite sound settings as custom presets and transfer them in a JSON file for reuse. Video Volume Booster supports SDR H.264 video with AAC mono or stereo audio at 44.1 or 48 kHz. It copies compatible video streams and processes the selected audio track into the saved MP4. If your video has multiple audio tracks, choose which one to include. Unsupported codecs, HDR and multichannel sources may be refused with an explanation. Amplifying a recording can also make background noise louder. The app adjusts existing audio; it doesn't remove noise, restore missing dialogue, repair distortion or change the volume of other apps. Peak protection is not a guaranteed true-peak ceiling after AAC encoding. Choose a quiet clip, compare your adjustments and give the copy you share a sound level that works for you.

Give quiet clips a lift, compare the sound and save a louder copy to share. Try it with your next video.
