How to improve vocals from Blurays ?

[Bsmooth]

Just started getting my blurays discs on a hardrive using MKV and Handbrake. I'm a bit on in years and I guess my hearing isn't what it used to be. I'm finding it a bit difficult hearing vocals from movies after I get the files onto my HD. I'm watching on a pretty old Samsung, but no night settings to play with.
In your experience is there a way to improve settings in Handbrake to improve the vocals a bit? I read you can set the audio Dynamic compression between 1 and 2.5, but not sure where might be the best place.
Its strange If I watch the same movie being broadcast the vocals seem fine, but from a bluray rip they are very quiet.
Also do the audio settings like mixing from say an AC3 to AAC make a difference in vocals as well, lots of options here. Right now I mix them down to stereo, but maybe lose vocals in the process somewhere?.
I also have subtitles on and usually have a few choices including SRT files as well.
Any help would be greatly appreciated.

The only way to to improve audio is with an audio editor such as Audacity.

So you have to run the entire film thru Audacity, minds as well make the movie myself.

Depending on your computer if its fast enough it would only take a few minutes,you don't need to run the movie.

You could try this open source software & set the volume manually by listening to the increased volume so as not to gain audio distortion as there is no clipping setting. It's just a quick solution which serves most peoples needs.

For the audio, specially if you downmix ac3/aac 6 channels to stereo there are special filters to improve the volume of the speech without clipping, in clever FFmpeg-GUI.
If you are interested, I will post a tutorial.

VidCoder can do this, I use it to boost audio by a couple of dB when converting and it will rip your blu-ray/dvd to x265 for better compression for smaller filesize and use your GPU to speed up encoding quite a lot


Its basically a front-end for Handbrake and its 100% free

So how do you do it with Audacity?

It's an audio editor, you can do a lot of things if you understand some basic concepts.

Probably best to get the audio into the program and see what the wavform looks like.

Perhaps you can post a sample or at least some screenshots
