How do i increase the audio level on a quiet video track.

[TinderboxUK]

One of my Anime series, The Japaneses audio is loud but the English is a lot quiet, Is there any way to boost or normalize the audio level.

I have tried looking for an gain in the audio tab but cannot find anything, I did a search and a couple of fixes were mentioned but i cannot find them in the latest version, something to do with adding normalize to FFmpeg

If you try to help me can you make sure it works in the latest version

I use the HEVC VCEEnc codec for my AMD gpu.

Thanks.
