I wish it worked even better to reduce sounds and increase the volume of dialogue. Background sounds and special effects sounds are still so much louder than barely audible dialogue.
I totally agree. I use ffmpeg's dynaudnorm[0] filter in mpv/IINA when watching media to better normalize sound volume. It's the best audio normalizer I’ve used. No loss of dynamic range within the target window duration. (~15 seconds by default, but I tweak it to around ~8 seconds)
If you increase volume on the center channel while reducing overall volume the dialogue usually gets much clearer.
Is there a tool that lets me analyze video and make this change, or does it generally require an audio interface?
I find I have this problem with Chromecast and YouTube. I think I would be pretty happy if I could set up yt-dlp to grab video, assist the audio of needed and then play the video.
Bless you. I appreciate this, and my mother who has some neurological issues related to auditory processing definitely appreciates it.
