16bit float to 32bit float in exr decoder with tables is not lossy, its lossless - no data is lost.

Treating floats as integers when compressing? I doubt one can get any big compression gain that way, at least for audio case it is bad...

Are these real 32bit float EXR files - with natural (camera footage) content and one with synthetic (blender rendered ones) non trivial content? EXR have just bad lossless 32-bit float...

I have better tool that 100% recovers files, contact me for code.

The only normalization I see in code of smplayer is volnorm, very fragile and abandoned filter from mpv side. The only other filter used in smplayer is acompressor without any...

Are you sure your smplayer installation is still using volnorm? What smplayer version you use? I really doubt you actually use volnorm, unless you still use old mpv with old...

Never use loudnorm in single-pass, it is very bad.

dynaudnorm is dynamic normalization, and that may not be always wanted, but with big frame sizes and/or gausssize you will get behavior that is very similar but never same to...

It not common, jack use fixed number of samples anyway.
