Suggestion: Audio Amplification about webmconverter HOT 4 CLOSED

Tested filter shared and not a big difference without.

from webmconverter.

Using a source video with very low volume, I tried adding -filter:a "volume=40dB" as a test in the Arguments section at the Advanced tab after the -c:a parameter. It worked, but the 40dB volume increase was just a guess without prior volume detection - a bad guess can make the audio too loud.

To solve this, I ran the command ffmpeg -i input.mp4 -lavfi "volumedetect" -f null /dev/null, and got a max_volume: -42.2 dB value in the log results. I then used that same value for the amplification filter as a positive value (while reducing it by -3dB to keep the volume reasonable) and got -filter:a "volume=39.2dB" to use with the Webm Converter. This is the function I'm hoping you consider adding to the Processing section.

This is the final result for the .webm:
