Hello, FFmpeg developers.

I am making my first steps in developing FFmpeg filters. I don't know if 
this filter was invented by copilot based on my prompts or if it 
exists/used to exist in other versions/forks. There is one reference to 
a ffmpeg wavefilt.c on search engines. I am really sorry I am not 
proficient with git and not sending this piece of code using the 
recommended procedure.

Is an enhanced waves video filter of any interest ? Used FFmpeg 6.0.

Best regards,

Jim
