Two decades ago I was heavily involved in a music restoration project of live concert performances 
(with the approval of the band). I used compression extensively. Most commercial recordings are 
compressed, meaning: the peaks are made uniform without clipping, so volume is made uniform -- I'm 
trying hard to not use the word "equalize" here because the word "equalization" is so misused.

Try compression. It's what the professionals use.

That said, I don't know what FFmpeg means by "compression". Is it what audio engineers mean by 
"compression"? I don't know.
