When your recorded video volume is too low or too loud, this tool allows you to losslessly adjust the loudness of the audio track. Utilizing FFmpeg stream-level processing technology, it achieves volume adjustments within a ±24dB range through the PCM sample linear scaling formula (Output Sample = Input Sample × 10^(dB/20)), preserving the original video quality and audio-video synchronization.
Q: How can I avoid distortion after adjusting the volume?
Keep the gain within +18dB and utilize the built-in anti-overflow feature.
Q: Will adjusting the volume affect the video quality?
No. This tool only processes the audio track; the video encoding parameters remain completely unchanged.
We recommend previewing the effect first if the gain exceeds +12dB. The input file must contain a valid audio stream. Please ensure a stable internet connection when processing large files.
For professional users, we recommend normalizing multiple video clips to a standard loudness of -23 LUFS. Typical use case: Boosting a quiet conference recording from -30dB to -12dB can increase vocal clarity by 4 times without introducing distortion.
